Keep the paper away from high humidity. (It must be less than 70%) 3. Put the paper on a flat place 4. If you will keep the paper in the custody, which you have already unpacked, put it into the polyethylene bag to avoid the humidity.
CAUTION Do not use the paper with staple, or do not use such conductive paper as aluminium foil and carbon paper. The above may result in a danger of fire NOTE (1) Print image may become light if printed on a rough surface of the paper. (2) Print image may become defective if the print paper has an excess curl. (3) It will become a cause for paper mis-feed, defective print image or paper creasing if you use a paper that does not satisfy the specification. (4) Do not use a paper of which surface is very special, such as thermal paper, art paper, aluminium foil, carbon paper and conductive paper. (5) Do not use papers with unpacked (exposed in high / low temperature & humidity) in a long period. Such papers may result in mis-feed, defective image or paper creasing. (6) Tracing paper exposed to air over a long period tends to cause a defective printing. Removing one round on the surface of the tracing roll paper from the beginning is recommended. Refer to [2.3 Replacing Roll Media].

NOTE (cont) (2) It is unnecessary to raise the machine this time. Just taking a level is enough. (The machine will be raised after the next procedure.) (3) The most important thing for achieving correct machine level (= correct color registration) with minimum effort is to place the water level always at the same position by the same orientation. Such high accuracy water level may show different measurement result if only its location on the base plate is changed from one to another even if the machine angle is the same. Just changing its orientation (left-right) will result in the same problem. Please make sure to do the following a), b) and c) at each measurement points to avoid such incorrect measurement. a) Clean the surface of bottom plate where the water level is to be placed. Clean the bottom of water level as well. b) Once you decide where to place the water level on the bottom plate, mark this position by drawing lines with pen. And make sure to place the water level within marking lines whenever you take measurement again in later occasion.
Mark the position with pen.

3. 1 General Outline of the Print Process
3. 1. 1 Characteristic of toner The toner of KIP product has a characteristic to be charged “negative”, which tends to stick to a more “positive” object. Suppose that there are objects A and B, and the situation is as follows. 1. Electric potential of the object B is higher than that of object A. 2. Toner exists on the object A. Comparing the potential of both objects, it can be said that the object B is relatively “positive” and the object A is “negative”. (In another word, object B is more “positive” than the object A.) As the toner is “negative”, it sticks to the object B that is more “positive”. If you move the object B close to the object A, therefore, the toner moves onto the object B. Object A with low potential (Relatively negative) Toner moves from A to B. Object B with high potential (Relatively positive) On the contrary, suppose that the toner exists on the object B of which electric potential is higher than the object A. Even if you move the object A close to the object B, the toner continues to stay on the object B because negative toner and relatively negative object A repel each other. Object A with low potential (Relatively negative) Toner stays on B. Object B with high potential (Relatively positive) Thus, the toner has a characteristic to move from one place with a lower potential to another place with a higher potential. And the bigger difference of voltage between objects A and B allows more toner to move between them. If we control the electric potentials, it is possible to move the toner from one place to another as we intend, or it is also possible to remove the toner from an unwanted place. KIP C7800 controls the electric potentials properly operating each part as Drum, Corona Units and Developer Unit. The movement of toner is controlled correctly and several processes as Development, Toner Transfer, Drum Cleaning and etc. are performed.

3. 2 Description of Each Step of Print Process
3. 2. 1 Cutting the media Each of 3 Roll Decks is equipped with slider cutter. Media feeding has to be stopped temporarily when the slider cutter is going to cut the media, which is accomplished by 2 different ways according to the length of print. - If the print image is long so the leading edge of media is beyond Registration Sensor when the
slider cutter is going to cut, a loop of media is created in the bottom transportation unit before cutting so that cutting action should not affect print image. This allows the printer to continue to transport the media at toner transfer points while it stops media feeding temporarily in the cutter unit to cut the media straight.
Registration Sensor Loop of media

- If the print image is short so the leading edge of media does not arrive at Registration Sensor when the slider cutter is going to cut, the media feeding mechanism directly stops media feeding and the cutter cuts the media

3. 2. 2 Tightening the media (long print only) Better print quality can be achieved if the long media is tightened during transportation at around Registration Roller section. The running speed of media feeding system is automatically controlled most appropriately to achieve this. The system takes it as long print if the length of media is longer than the double size of each standard size. When a long print starts and the media firmly sticks to the Feeding Belt, the running speed of media feeding system (before Registration Roller section) gets slower, which as a result tightens the media. When the media is tightened, it moves up the Tension Roller which is located at the exit of Bottom Transportation Unit. As the white reflection plate moves down accordingly to the movement of Tension Roller at this time, the Tension Sensor surely detects how much the Tension Roller is moved up by detecting the distance from white reflection plate. When the media is too much tightened and the distance between Tension Sensor and white reflection plate becomes wide enough, the running speed of media feeding system gets a little faster to decrease the media tension. And when the distance becomes narrow enough, the running speed gets faster to tighten the media again. Thus, the tension of media is controlled most appropriately.

3. 2. 3 Media Charging The Media Charge Roller is moved up and contacted to the Belt immediately when printing starts. The Media Charge Roller is applied with a high tension voltage of +1200V, while the driving roller of Belt is directly connected to the ground. When the media comes between Belt and Media Charge Roller, it is charged positive by the Media Charge Roller. On the other hand, the driving roller of Belt collects negative charges from the ground due to the effect of electric induction, which as a result charges the Belt negative. As positive media and negative belt firmly pull toward each other, belt transports the media upward. Driving roller Media Charge Roller +1200V

3. 2. 4 Erasing Some negative electric charges are still remaining on the Drum after completing previous image process. These negative charges must be removed before starting the next image process. As the Drum has a characteristic to lose the negative electric charges when exposed to the light, it is rotated and evenly exposed to the infrared light from the Eraser Lamp. All electric potential are removed so the Drum surface becomes 0V. Eraser Lamp Negative charges
K125sm3e1 3-10
3. 2. 5 Drum charging The Image Corona takes negative discharging, and the Drum surface is charged negatively with -XV evenly by this process. The Drum area charged with -XV corresponds to the white area of the printed image pattern.
Image Corona Wire
K125sm3e1 3-11
3. 2. 6 Exposure According to the printed image pattern, the LED Head throws light onto a certain area of the Drum that corresponds to the black area of printed image pattern. As the Drum has a characteristic to lose the negative electric charges if it is exposed to the light, the potential of this exposed area is increased to about -YV. The other part of Drum surface not exposed to the LED light keeps -XV of Surface Potential which has been given by the Image Corona. -XV < -YV An invisible electric image pattern that consists of -XV area and -YV area is formed on the surface of Drum as a result. (This is called “Electrostatic Latent Image”.)

3. 2. 7 Development Developer Roller of each color is evenly covered with the toner, and it is contacted to the Drum firmly. It is supplied with about -200V of Developer Bias which is flexibly adjusted by the Auto Density Control. On the other hand, an Electrostatic Latent Image consisting of -XV area and -YV area exists on the Drum. The relationship among -XV, -YV and about -200V are as follows. -XV (Drum charged by Image Corona) < about -200V (Dev. Bias) < -YV (Drum exposed to LED light) Seen from about -200V of Developer Roller, -YV area on the Drum that was exposed to the LED light is relatively “positive”, so the toner moves from the Developer Roller to this area of Drum. On the other hand, the -XV area of Drum is relatively “negative” seen from the Developer Roller (about -200V), so the toner does not move to this area of Drum but remains on the Developer Roller. A visible toner image is created on the Drum as a result. The value of Developer Bias “-YV” is not constant but is compensated flexibly and most appropriately within -150V to -250V by the Density Control. (See [3.4 Density Control] for the detail.)

Transfer Roller is provided with +300V to +2000V of Transfer Bias. The toner on “negative” Drum surface transfers onto the media as it is attracted by “positive” Transfer Roller. Belt Media Transfer Bias (+300V to +2000V) is applied very slightly after the media has passes by the Transfer Roller so as to have non-toner image area on the lead edge.

3. 2. 9 Separation of media The printing media strongly sticks to the Belt after the Transfer being pulled by the static force. It is separated mechanically by the Separation Fingers (Plastic sheets). - Normally the Separation Fingers are separated
from the Belt so as not to wear it by the friction. Separated

3. 2.10 Fusing Printing media with unfused toner image runs along the Fuser Entrance Guide being pressed by the air from blowers, and it is fed in between Fuser Roller and Pressure Roller. The toner image is firmly fused onto the printing media by the heat and the pressure given by Fuser Roller and Pressure Roller. Printing media is tensioned between Belt Unit and Fuser Roller. As it is better giving same tension to the media constantly throughout printing, C7800 has Tension Sensor. The angle of Fuser Entrance Guide changes as the media is tightened, which also changes the height of white reflection plate above Tension Sensor. Tension Sensor is always monitoring the distance from white reflection plate. When it detects the distance gets too wide, this means the Fuser Entrance Guide is too much tightened. The Fuser Motor rotates in slower speed in this case to decrease media tension. On the contrary if the distance between sensor and white reflection plate gets too narrow, the Fuser Mot rotates in faster speed to give tension to the media.

3. 3 Controlling the movement of toner in the Developer Unit Developer Unit is provided with 3 rollers “Developer Roller”, “Blade Roller” and “Toner Supply Roller”, which are provided with their own Bias respectively as the following table. The voltage of the Developer Roller (-YV) is measured against the ground, and the voltages for other items are the difference against the voltage “-YV” of Developer Bias.
Name of roller Supplied voltage Developer Roller About -200V against the ground Blade Roller (Center) -50V against the Developer Roller Bias Blade Roller (Both sides) +300V against the Developer Roller Bias Toner Supply Roller -100 +/-3V against the Developer Roller Bias
Blade Roller : Both sides Blade Roller : Center (+300V against the Developer Roller voltage) (-30V against the Developer Roller voltage) Insulator Developer Roller (about -200V against GND) Toner Supply Roller (-100V against the Developer Roller voltage)
NOTE The insulator divides the Blade Roller into “center” and “both side”. Different voltage is provided to them respectively.
K125sm3e1 3-23
Taking advantage of the difference of potentials among these rollers, the movement of toner is controlled in the Developer Unit as follows. 1. The Toner Supply Roller carries the toner toward the Developer Roller. 2. The voltage of the Toner Supply Roller is 100V lower than that of Developer Roller. When the toner reaches the contact point of these rollers, it moves onto the Developer Roller. Then the Development Roller carries the toner toward the Blade Roller. 3. The Blade Roller is strongly pressed to the Developer Roller by the spring, and these 2 rollers move to the opposite direction each other at the contact point. The Developer Roller carries much toner, but the Blade Roller limits the amount of toner that can pass through between 2 rollers. As a result very small amount of toner can pass through between rollers and the rest is returned back to the inside. As the voltage of Developer Roller is 50V higher than that of Blade Roller (Center), the toner passed through between rollers surely sticks to the Developer Roller. Very thin layer of toner is evenly formed on the surface of Developer Roller as a result. 4. Lots of toner that could not pass through between 2 rollers is returned to the inside of Developer Unit. The toner sticking on the Blade Roller is scraped off by the Scraper which is contacted to the Blade Roller.

5. The voltage of both sides of Blade Roller is higher than the voltage of Developer Roller by 300V. When the toner reaches the contact point of these rollers, it sticks to the Blade Roller. The side areas of the Developer Roller are not covered with the toner as a result, which can prevent the toner drops into the machine from the side.

3. 4 Automatic Controls
3. 4. 1 Density Control If the Developer Bias is always constant, the image density is changed when the surrounding temperature changes. To get rid of any effect by the temperature, the Auto Density Control compensates the Developer Bias flexibly to the most appropriate level monitoring the change of density with the Density Sensor. KIP Color 80 memorizes a “Target Density” for each of CMYK which has been specified in the factory by Density Lock. The Auto Density Control is a process to reproduce the “Target Density” in any temperature condition. Without Auto Density Control With Auto Density Control Wanted density Resulting density (Look different from “wanted”) (Look same with “wanted”)
K125sm3e2 3-26
3. 4. 1. 1 Density Lock Density Lock is performed in the following way. (Readjustment of Target Density is available in the market by the same way.) This section introduces a summary of Density Lock. For detailed procedure, see 9.1. 1. For avoiding that the Auto Density Controls unexpectedly changes the Developer Bias when you are adjusting it manually, cancel them in the K125GUI. 2. Enter the reference Developer Bias setting. 3. Print out “K125DensityCheck.zip”, and then measure and average the toner density in the
designated patch images. If the density does not meet the target density, adjust the Developer Bias.
K125sm3e2 3-27
4. When requested densities have been achieved, execute Density Lock to memorize the present densities as “Target Densities”.
The following operation is performed automatically in the Density Lock Process of each color.
(1) Print process takes place without printing media, and several toner patches of CMYKare created on the surface of Belt.
(2) Belt conveys the density patches toward the Density Sensor. (3) Density sensor throws light onto density patches and reads the reflected light per patch. (4) Firmware gets the average value of 8 reflected light levels of each color, and memorizes it as Target Density.

3. 4. 1. 2 Density Control Density Control can be activated or inactivated in the following page of the KipDiagColor.
Selectable settings Description Auto std Density control takes place automatically when printer is turned on
while fusing temperature is colder than 50 degrees. Checking level for achieving requested density is normal. (And also the operator can execute density control manually anytime.)
Auto high Density control takes place automatically when printer is turned on while fusing temperature is colder than 50 degrees. Checking level for achieving requested density is stricter than “Auto std”. (And also the operator can execute density control manually anytime.)
Manual std An operator executes density control manually whenever he thinks necessary. Checking level for achieving requested density is normal.
Manual high An operator executes density control manually whenever he thinks necessary. Checking level for achieving requested density is stricter than “Auto std”.
K125sm3e2 3-29
Density Control adjusts the density as follows.
(1) Print process takes place without printing media, and 8 each CMYK of density patch is created on the surface of Belt.
(2) Belt conveys the density patches toward the Density Sensor. (3) Density sensor throws light onto density patches and reads the reflected light per patch. (4) Firmware gets the average value of 8 reflected light levels (= density) of each color. (5) Firmware compares the average density of each CMYK with Target Density. If the average is within tolerance of Target Density it means correct density has been achieved, so Density Control finishes adjustment. If not within tolerance, Density Controls tries the same thing (1 to 5) again. (6) If correct density is still not achieved after 5 times trials, Density Control error is shown.

3. 4. 2 Automatic Transfer Roller Voltage Adjustment Optimum voltage that is to be applied to the Transfer Roller is not always constant but varies flexibly according to the variation of environmental condition. KIP c7800 printer has ability to automatically calculates the optimum voltage with considering the environmental condition. [Technical detail of Automatic Transfer Roller Voltage Adjustment] When printing starts and the Transfer Roller is energized, printer monitors the electric current applied to the Transfer Roller as the first step. Monitoring of electric current takes place when there is no printing media on the Belt during printing operation. When monitoring of current finishes then the printer compares it with the Transfer Roller Target Current which is specified by the concerning service mode in advance. Each print speed has its own Transfer Roller Target Current value as shown in the following list.
Print speed Transfer Roller Target Current Concerning service mode 60mm/sec 40μA 2453 : auto adjust transfer voltage target current (60mm/s) 100mm/sec 70μA 2454 : auto adjust transfer voltage target current (100mm/s) 120mm/sec 85μA 2455 : auto adjust transfer voltage target current (120mm/s)
When the monitored electric current does not corresponds to the Transfer Roller Target Current, printer automatically adjusts the voltage for Transfer Roller to the optimum value so that the monitored current should corresponds to the Transfer Roller Target Current. This optimum voltage for Transfer Roller, which is automatically adjusted by the printer, is called Standard Constant Voltage and applied to the Transfer Roller by "constant voltage control". - Standard Constant Voltage is applied to the Transfer Roller just as it is (without compensation) when no media is running between Drum and concerning Transfer Roller. - When media is running between Drum and concerning Transfer Roller, Transfer Roller is applied with Compensated Constant Voltage which is the Standard Constant Voltage additionally compensated by the service mode. [Compensated Constant Voltage] = [Standard Constant Voltage] + [XV] Amount of compensation (additional XV) is specified in the service modes 2468 to 2503 (Transfer Roller Voltage Offset), with considering such conditions as process color (#1-4), print speeds and print widths. Belt Standard Constant Voltage is applied to these TR Rollers. (Media is not running between TR Roller and Drum) Compensated Constant Voltage is applied to these TR Rollers. (Media is running between TR Roller and Drum)

(1) When printing with film, printer does not perform Automatic Transfer Roller Voltage Adjustment explained in the above, but it behaves in different way. In case of film, printer utilizes another service mode setting that sets fixed Transfer Roller Voltage to each humidity conditions 5%, 20%, 40% and 60%. When printer is going to start printing with film, it detects the current humidity first, and then refers to the fixed Transfer Roller Voltages set to the closest 2 humidity conditions. (If current humidity is 25% for example, printer refers to the ones set to 20% and 40%). Then it calculates a proper Transfer Roller Voltage for the current humidity from these reference values. The following service modes set fixed Transfer Roller Voltages that are utilized when printing with film. 473 to 488 (Process 1, 60mm/s, Film #1-4, Humidity 5/20/40/60%) 553 to 568 (Process 1, 100mm/s, Film #1-4, Humidity 5/20/40/60%) 633 to 648 (Process 1, 120mm/s, Film #1-4, Humidity 5/20/40/60%) 713 to 728 (Process 2, 60mm/s, Film #1-4, Humidity 5/20/40/60%) 793 to 800, and 1481 to 1488 (Process 2, 100mm/s, Film #1-4, Humidity 5/20/40/60%) 1553 to 1568 (Process 2, 120mm/s, Film #1-4, Humidity 5/20/40/60%)

If this harness is not connected correctly, the behaviour of printer to decide the Transfer Roller Voltage is just as same as the way for film, which is explained in the above reference (1).

NOTE When you take several mechanical operations as instructed in this chapter, you will often need to open the Rear Cover and draw out the Process Unit. Please make sure to satisfy the following requirements in that case. (1) Make sure to open the Rear Cover (with Belt Unit) first and then draw out the Process
Unit next. Drum or Belt may possibly be damaged if you draw out the Process Unit without opening the Rear Cover.
(2) Drum is exposed to the light when you open the Rear Cover or draw out the Process
Unit, which may possibly damage the Drum. Drum must NEVER been exposed to the direct sunlight! Even if the light is not the direct sunlight but the room illumination, it is not good to expose the Drum to such light for long time. Please minimize the time of exposure, or preferably put the Drum in an exclusive box to avoid any light.

Voltage to Transfer Roller
8 Is the problem fixed if you increase the voltage to Transfer Roller in Service Mode?
Yes OK
NOTE Setting the value of Transfer Roller Voltage Offset to higher value is effective for keeping the white (blank) image area of CAD print in a good quality condition. However, too high value may badly affect the color, so it is important to increase the value little by little with checking the actual image so as not to uincrease too much. On the contrary, it is necessary to pay more attention to the image color rather than white (blank) image area when printing a poster or graphic image. In this case it is recommended to decrease the value of Transfer Roller Voltage Offset as there is a tendency that smaller value is more effective for better image color. Also it tends to be difficult to keep the white (blank) image area of CAD print in a good quality condition when in low humudity environment. Therefore, it is also recommended to change the value of Transfer Roller Voltage Offset according to the seasonal change, e.g. setting it to higher valur when in low humidity season and also setting it to lower value when in high humidity season. Choose the following addresses (item numbers) in Setting of Service Mode if you will change the Transfer Roller Voltage Offset. 2468 - 2470 : Transfer roller voltage offset [K, 60mm (Gloss/Heavy in color)] 2471 - 2473 : Transfer roller voltage offset [K, 100mm (Bond/Vellum/Film in color)] 2474 - 2476 : Transfer roller voltage offset [K, 120mm (monochrome)] 2477 - 2479 : Transfer roller voltage offset [C, 60mm (Gloss/Heavy in color)] 2480 - 2482 : Transfer roller voltage offset [C, 100mm (Bond/Vellum/Film in color)] 2483 - 2485 : Transfer roller voltage offset [C, 120mm (monochrome)] 2486 - 2488 : Transfer roller voltage offset [M, 60mm (Gloss/Heavy in color)] 2489 - 2491 : Transfer roller voltage offset [M, 100mm (Bond/Vellum/Film in color)] 2492 - 2494 : Transfer roller voltage offset [M, 120mm (monochrome)] 2495 - 2497 : Transfer roller voltage offset [Y, 60mm (Gloss/Heavy in color)] 2498 - 2500 : Transfer roller voltage offset [Y, 100mm (Bond/Vellum/Film in color)] 2501 - 2503 : Transfer roller voltage offset [Y, 120mm (monochrome)]

8. 3. 3. 7 Cut Length “cut length” is an automatic process to compensate the cut length and the leading registration at a time. In this process, the system automatically starts sample printing (5 sheets in 8.5 inch long and then another 5 in 48 inch) with a selected Roll Deck. Color Sensor detects the sheets’ feed distance, and then the system adjusts the Cutter operation timing to get 8.5 or 48 inch long sheet. It takes about 5 minutes for cut length adjustment against “all” decks to complete. For one deck only, it takes about 2 minutes. A plain paper / bond roll media (remaining 8 meters or longer, the width does not matter) should be loaded to a Roll Deck you want to have cut length adjustment. (Each Roll Deck has a parameter of “cutter timing”) Furthermore, during cut length adjustment, the system performs leading registration adjustment at the same time. When cult length adjustment is done against one Roll Deck, leading registration will be also adjusted to the Roll Deck, and the result will be applied to the other Roll Deck. (All Roll Decks uses a common parameter of “leading registration”) 1. Load a roll media in the Roll Deck to be adjusted.
NOTE [cut length] is only available with service mode active.
NOTE This mode is only for factory use. Please do not operate this in the field as it may negatively affect the Color Registration quality.

8. 4. 2. 3 Setting Detail This section introduces all the settings expected to be used in the field in order of item number. Some item titles have its brief summary for better understanding. 0001 iso / ansi No.0001 decides the basic format of inch or metric.
Setting value Contents 0 ISO: metric format series 1 ANSI: inch format series
Reference
No.0001 is effective only to the size format selection available in the UI screen. This does not effect to the counting “unit”.
NOTE (1) It is highly recommended to backup the current parameters prior to setting change.
For backup procedure, see [8.4.8.1 How to create printer setting]. (2) The default values of “setting” vary by individual printers. Open a backup INI which has
been created just before starting setting change or at the machine setup to confirm the default settings. In case you cannot confirm any backup INI at once, find a possible proper setting value for a particular machine by yourself based on [8.4.2.2] or get a factory default.
(3) Setting “No.1” is displayed as “No.0001” in some screens. (4) Some setting items are subdivided by Process Unit # (Color, K/C/M/Y), media type (plain,
tracing, film, gloss, heavy), subtype (#1 to #4 for each media type), print speed (60/100/120mm/s) or humidity range.

0019 long print trailing blank setting No.0019 is a switch whether the KIP C7800 adds a 1.1m blank (and a 0.4m margin on top at a time) for a long print (longer than 2x standard). The blank areas (at LE/TE) will be held in the Roll Deck throughout printing process of a long print image for more precise color registration.
Setting value Contents 0 Long Prints (longer than 2x standard) is cut in a given print size. 1 Long Prints (longer than 2x standard) has blank areas of 0.4m on top / 1.1m added.
0069 maximum print length No.0069 decides the limit of the print (cut) length which the print engine can accept. See also the controller, software, file format limitation (if any).
Setting Value Contents 0 6 meters 1 no limit based on mechanical / print sequence control
NOTE (1) The limits for print quality guarantee are listed below.
plain paper 5x standard length (max, varies by Roll Deck) tracing paper 1x standard length film 1x standard length glossy paper 1x standard length
(2) Setting Value “1” allows for “no limit” based on mechanical / print sequence control. The
print length depends on any limitation according to the controller software / RIP software / file format specifications.
NOTE (1) Image quality and feed reliability for long prints are not guaranteed with No.0019 set to
“0” (OFF). (2) The definition of “long print” (2x or 3x) is set by No.229.

0072 tension control target No.0072 is a parameter of the Fuser Tension Sensor to decide the Target Tension. (the standard angle of Fuser Entrance Guide) Increase the value to raise the Target Tension. 0073 tension control gain No.0073 is a parameter of speed change of Fuser Motor to maintain the Target Tension. Increasing the value gets a bigger unit of speed change of Fuser Motor. 0074 tension control offset delay No.0074 is a correction factor of speed change of Fuser Motor to maintain the Target Tension. Increasing the value gets a bigger unit of speed change of Fuser Motor. 0079 web feed No.0079 is a mode selector to change the pace of forwarding web cleaner. The faster web proceeds, the more cleaning performance comes.
Setting value Contents 0 Web proceeds by the standard speed, 0.15mm in 500mm printing. 1 Web proceeds by the standard speed, 0.3mm in 500mm printing. 2 Web proceeds by the standard speed, 0.6mm in 500mm printing.
0080 print end web setting No.0080 is a switch whether the KIP c7800 forwards the web cleaner in 3mm every after completion of a print operation.
Setting value Contents 0 Inactive 1 Web proceeds by 3mm after completion of a print operation to provide fresh web
cleaner surface.
NOTE This setting has been factory-adjusted. Keep the value unchanged.
NOTE Tension Control has been factory-adjusted in cooperation with No.0073 to 0079. Keep the value unchanged or Tension Control may malfunction.

0139 to 0142 developer roller bias offset (applied when pint speed is 60mm/sec) These modes specify the offset of developer roller bias, which is applied only when the print speed is 60mm/sec (Gloss and Heavy in color mode). Setting value stands for the voltage differential from the standard developer roller bias which is specified by BUD No.113 to 116. If developer roller bias is set to 180 (-180V) in BUD No.113 (developer roller bias [K]) and also voltage differential is set to +10V in BUD No.139 (developer roller bias offset), the actual voltage applied to the developer roller is -170V being calculated by the following formula. -180 + 10 = -170 Increment of the value makes the printed image darker.

0205 mono print feed mode No.0205 decides the operation position for Process Units C/M/Y in monochrome printing. In monochrome printing, only the Process Unit K operates and the other Process Units C/M/Y stay at “standby position”. This feature allows the Process Units C/M/Y to operate as the color printing (without C/M/Y toner). Therefore, the media is transported by not only the Process Unit K but all the 4 Process Units to ensure media feed performance for narrower media.

0207 to 0226 flapper control solenoid pwm duty The Fuser Entrance Guide detects its tilt due to pressure from the media tension. It has a rotary solenoid on its shaft, machine right side. These are a parameter of torque change on the rotary solenoid to decide the detection fineness of the tilted angle. Increasing the value increases the duty on the motion (= rises the torque) of the rotary solenoid, thus the Fuser Entrance Guide tilts in a less angle by a certain pressure. This is because the Fuser Entrance Guide can bear stronger media tension.

0229 long print control change point This defines the minimum length of “long print”. Setting value 20 defines that the long print is “twice as long as each standard portrait length”. Defined lengths are different per media widths such as; - 841mm wide roll media : 2378mm or longer is judges as long print (1189mm x2=2378mm) - 594mm side roll media : 1982mm or longer is judges as long print (841mm x2=1982mm)
Setting Range Step of Increment 20 to 30 0.1m
When a print is longer than (or just as long as) the defined length, the printer takes automatic tension control by the Tension Roller in the Bottom Transportation Unit. Maximum length available is "3 times as long as standard size" which is achieved when this is set to 30.

The printer categorizes every single pixel of print data into any of 10 IE Categories depending on its “visual appeal power”. 2 elements concern for the categorization, such as “isolate level” and “existence of nearby dot”.
• “Isolate level” stands for the isolation from other images, and shown by the “numeral” of IE Category as A1 or A2. A larger value stands for more isolation from other images (as single pixel). “More isolation” reduces the “visual appeal power” of the target pixel. Therefore more image enhancement is required for more isolated pixel to print it much darker.
• “Existence of nearby dot” is shown by the alphabet of IE Category as A1 or B1. Nearby dot exists when “B”, and does not exist when “A”. As the existence of nearby dot provides more “visual appeal power” to the concerning pixel, less image enhancement is required.
The followings are the descriptions of 10 IE Categories, which are ordered from top to bottom in terms of their visual appeal power. (Upper item has more visual appeal power.) B5 : Isolate level 5 with nearby dot Having much visual appeal power A5 : Isolate level 5 without nearby dot (Needs less image enhancement) B4 : Isolate level 4 with nearby dot A4 : Isolate level 4 without nearby dot B3 : Isolate level 3 with nearby dot A3 : Isolate level 3 without nearby dot B2 : Isolate level 2 with nearby dot A2 : Isolate level 2 without nearby dot B1 : Isolate level 1 with nearby dot A1 : Isolate level 1 without nearby dot Having less visual appeal power (Needs more image enhancement)

2468 to 2503 transfer roller voltage offset These items specify the voltages that are applied to the Transfer Roller. The voltage specified here is applied to the Transfer Roller only when a printing media is running between Drum and concerning Transfer Roller. Setting value stands for "additional XV" against the optimum voltage calculated automatically by the Auto Transfer Roller Voltage Adjustment function. (When there no media is running between drum and concerning Transfer Roller, the optimum voltage calculated by the Auto Transfer Roller Voltage Adjustment function is simply applied as it is.) Setting the value of Transfer Roller Voltage Offset to higher value is effective for keeping the white (blank) image area of CAD print in a good quality condition. On the contrary, decrement of the value for a poster/graphic image tends to be more effective for better image color.

When no media is running between the Drum and the concerning Transfer Roller, the optimum voltage calculated by the Auto Transfer Roller Voltage Adjustment function is simply applied without being compensated by the offset voltage specified here. When media arrives the concerning Transfer Roller, the voltage applied to the Transfer Roller is the sum of "optimum voltage" and "offset voltage".

8. 4. 5 Output Check Output Check is to monitor the current output signal status from electric components. Selecting one component operates it individually. 8. 4. 5. 1 How to select item to operate 1. Press to scroll pages to 2/3, and then press [output check]. 2. A warning message appears. Press [ok] to recall “output check device list”.
K125sm8e5 8-141
3. You can see the device list. Scroll the pages with ▲▼ buttons to select a desired component. (The example shows 0608: manual feed clutch) 4. Once a device is selected, operation status pops up. “value01: 00001” means “operating”. (The other lines “value02/03/04” are used only for [0008]) 5. To cancel the operation, press [cancel] on the bottom.
NOTE (1) NEVER operate any components regarding “high voltage” “drum motor” unless required
by a troubleshooting procedure. Doing so may damage the Drum. (2) Some components (such as fans) always operate. To check these, first press “stop all”.
This will stop (kill) all the components just like “stop due to Door Open / Jam”. Therefore, once “stop all” is applied, “ce-call (ff-f0)” appears.
(3) If you used “stop all”, turn off and on the printer to cancel “stop all” state after you finish checking.
(4) If once “stop all” is applied, do not operate the fuser lamps for a long period. Doing so may overheat to damage the thermostat because “stop all” kills temperature control.
(5) Only one component can be operated at a time.

9. 1 Adjusting Optical Density Density Control is a process to reproduce a satisfactory image quality (called “Target Density”) regardless of the printer’s environment such as temperature condition, by compensating Developer Bias. For further detailed description, see chapter 3. The Target Density has been factory-adjusted. This section describes how to set the “factory default” Target Density in the field, without a backup INI. This procedure requires a roll of 20# Standard Bond, and a densitometer. Readjust CMYK optical densities to the following target values by taking the following (1) to (35).

9. 3 Belt Skew Adjustment
9. 3. 1 Before Skew Correction Adjustment There are 3 possible causes of Belt Skew Error listed below.
(1) Re-confirm the leveling. The KIP c7800 requires a quite precise level. Poor leveling may cause Belt Skew. Re-confirm the leveling, and try leveling again if necessary.
(2) Clean Belt inner surface and Skew Correction Roller. Toner / oil dirt sticking on some areas listed below may cause Belt Skew. - Outside circumferences of the inner surface on both Belt rims - On the flared end part of the Skew Correction Roller Even slight amount of the nature oil on your hand would do. Wipe the said areas with an alcohol-moistured cloth.
(3) Check for smooth movement of Skew Correction Roller. If the Skew Correction Roller’s movement is not enough smooth when the roller is tensioned/released, it may cause Belt Skew. Checking procedure is shown on the next page.
K125sm9e4 9-19
Checking procedure for smooth movement of Skew Correction Roller 1. Open the Rear Door (Belt Unit) (1). Remove 2 joints (2) by removing 2 each E Ring (3). This will separate the Belt Unit (4) from the Rear Door (1). 2. Remove Belt Cleaner Unit (5). Refer to [5.8.1 Replacing BC Blade].

10. Re-couple the Belt Unit (4) and the Rear Door (1), and then close it. 11. To check the skew correction performance, an appreciable amount of running may be required. Run the Test Print in 20 sheets of A0, and then visually check the Belt location.
If the left side of the Belt (closer side at the Belt Unit open) runs A) less than 2mm or B) more than 9mm from the Skew Correction Roller’ flared end, the Belt is physically going skew. Go to [9.3.2 Skew Correction Adjustment].

9. 3. 2 Skew Correction Adjustment Run the Test Print in 20 sheets of A0, and then visually check the Belt location. If the Belt skew is still observed (less than 2mm / more than 9mm from the end) after (3) Check for smooth movement of Skew Correction Roller in [9.3.1 Before Skew Adjustment], a fine adjustment will be required. There are 3 skew cases and your case should be always applied to one of them. A) Roller’s flared end observed in more than 9mm skew to machine right = left hand side from rear = Belt Unit far side B) Roller’s flared end observed in less than 2mm, end pushed downward (stronger) skew to machine left = right hand side from rear = Belt Unit near side C) Roller’s flared end observed in less than 2mm, end pushed upward (weaker) skew to machine left = right hand side from rear = Belt Unit near side
less than 2mm: case B) or C)
more than 9mm: case A)

If skewing still happens, turn the Skew Adjuster (2) in another half revolution clockwise and then check the result until resolved. The Skew Adjuster (2) is usually locked by the Nut (3). To turn the Skew Adjuster (1), first put a smaller flathead screwdriver on the top of the Skew Adjuster. With holding the Skew Adjuster (1), release the Nut (3). Now you can turn the Skew Adjuster. To fasten the Skew Adjuster, keep holding the Skew Adjuster and tighten the Nut (3) alone.
