Front to Back Registration on the CS650 Family Front to Back Registration adjustment is in five steps:

• Paper tray side guide adjustment • Cross-Direction image registration (Centering Adj.) • Feed direction image registration timing (Restart-Timing Adj.) • Front side Chart Adjustment • Back side Chart Adjustment

1. Correct paper loading and tray side guide position adjustments are a must for the first step. Tray sidewalls should be adjusted 1mm away from the paper stack on each side as shown by the red lines in the picture below.

The PF-601Large Paper Tray has a special procedure to lock the paper deck at the top to adjust the top of the side guides as shown by the picture below.

The Copy Operations Operator Guide, page 4-14, has a complete description of how to set side guides. The CS650 Operator Guide is on the internet at: http://www.oceusa.com/main/view_media.jsp?CONTENT%3C%3Ecnt_id=10134198673376677&FOLDER%3C%3Efolder_id=9852723696640325&bmUID=1241119008876

2. Check the centering adjustment for the tray you are using. Press these operation panel buttons to create a test target: Machine screen / Adjustment Button / 01 Machine Adjustment / 01 Printer Adjustment / 02 Centering Adjustment Select the tray you are concerned about from the list (button turns green) and press the Copy button (top of the screen) then the Start key. This test target is created:

Fold the paper exactly in half along the red line. If the centering adjustment is correct, the fold and the centerline on the target will match. Specification is plus or minus 1.5mm. Adjust the values in this screen as needed to make the test target centerline match the fold.

3. Check the Lead Edge Margin (Restart Timing) adjustment for the tray you are using. Press these operation panel buttons to create a test target: Machine screen / Adjustment Button / 01 Machine Adjustment / 01 Printer Adjustment / 01 Restart Timing Select the tray you are concerned about from the list (button turns green) and press the Copy button (top of the screen) then the Start key. This test target is created:

The line in the diagram should be 20mm from the lead edge of the paper. Adjust the values for the tray you are concerned about as needed.

Note: Screen 1 of 4 in this adjustment is for normal weight and size paper (usually 8 ½ x 11, 80gsm). If your situation involves heavy (above 130gsm) or large (11 x 17 or bigger) there are additional “offset” adjustments for those situations and for duplex. When making these “offset” adjustments, be sure to use the actual size and weight paper involved when creating the test charts.

4. There are also adjustments for CD Magnification and FD Magnification (crosswise direction and feed direction) that can be checked against the specifications in the pictures below. Specifications are in millimeters. In general, if these need adjusting a service person should be called. FD Magnification Specification

5. Check that the Side 2 Lens Adjustment Mode is ON. From the machine operating panel press these keys: Utility Counter / User Setting / Common Setting / Side 2 Lens Adjustment Press the ON button and exit the mode by pressing OK and then Exit. The Horizontal adjustments in the next steps will not be grayed out and not possible unless the Side 2 mode is ON.

6. Front Side Chart Adjustment can be done in two ways:

• Adjusting irrespective of what paper is in the tray using the Machine Screen, Both Sides Adjust button

• Described here is the adjustment specific to the paper in the tray (valuable

for heavy stock and the adjustment can be saved in the Paper Library)

Machine Screen / Paper Settings button in the lower left Will show this screen – choose the tray that you are concerned with:

• Touch Change / Process Adjust then Both Sides Adjust on the Chart Adjustment screen

• Be sure that FRONT is selected. • Press Chart Adjustment

Use the Copy button to print the adjustment chart. When you have the chart, enter the measurements in millimeters for each dimension (1, 2, 3, etc.) in the boxes.

When the measurements are entered press Adjustment Start. Very Important! You must push the Adjustment Start button and then the Close and OK buttons repeatedly to get the adjustment to take. Closely follow the instructions in the black box at the top of each screen about pushing Close and OK. Not doing this part correctly is the most common reason that this adjustment does not appear to work. Most machines will need minimum adjustment for the Front Side. 7. Procedure for finding the screen for Rear Side Chart Adjustment is similar to the front adjustment.

• The adjustment described here is specific to this paper in this tray (valuable for heavy stock and the adjustment can be saved in the Paper Library)

Machine Screen / Paper Settings button / Touch Change / Both Sides Adjust

• Be sure that FRONT is selected:

7. This screen is a key difference between the Front and Back chart adjustments. Note that the BACK button is selected when pressing Chart Adjustment.

Use the Copy button to print the adjustment chart.

When you have the test chart, hold it with the side with the X (centering) and Y (timing) movement directions toward you check the registration match at the 4 points by holding the page to the light.

• Think of the objects on the side with the XY directions (marked “back”) as being fixed.

• The idea for adjustment is to move the side opposite (marked “front”) the XY directions to match.

• The X and Y arrow directions show how to enter + or – numbers to move the mark as you wish.

• Enter the appropriate numbers in the X and Y boxes on the operation panel.

When the measurements are entered press Adjustment Start. Very Important! You must push the Adjustment Start button and then the Close and OK buttons repeatedly to get the adjustment to take. Closely follow the instructions in the black box at the top of each screen about pushing Close and OK. Not doing this part correctly is the most common reason that this adjustment does not appear to work. To check your adjustment, print another test chart and hold it to the light: Machine screen / Paper Settings button in the lower left / Select your tray /

press Change / Both Sides Adjust / Chart Adjustment Use the Copy tab at the top to output a test chart. Run 4 or 5 test targets to confirm the adjustment result. Readjust if necessary. Specification for front to back registration is + or – 2mm Note: Using the terms front and back in this adjustment has proven to be confusing and should be avoided. Refer to the test target as having a fixed side with the directions and the “other” side that is moved to match.

8. When these adjustments are completed, it assures that the machine hardware is correct. If necessary, there are Image Shift controls in the Finishing tab of both the Fiery and Creo print drivers to refine the image position. Both Quark Express and Adobe In Design have a front to back registration feature as part of the program. Using them may be preferred to using the Fiery or Creo controls to line up front to back page registration. 9. Save the Registration Settings in the Paper Library The settings just completed are specific to both the Paper Type and the Paper Tray currently in use. To use them again they should be saved in the paper library.

Machine Screen / Paper Settings button in the lower left Will show this screen – choose the tray that you are concerned with: Press Register
