MX3501N Service Manual [4] OPERATIONAL DESCRIPTIONS

1. Document size detectionSize detection on the document trayThe document size is detected by the DSPF document width sensor (SPWS), and the document length is detected by the DSPF documentlength sensors (SPLS1, SPLS2). The document size is judged from the document width and the document length as shown in the table below.When, however, documents of different sizes are mixed and set on the document tray, the largest size is detected.

2. Timing chartTo increase the document replacement speed, pre-feed of the second and the later documents is performed for documents of A4/Letter orsmaller sizes. Therefore, a clutch is provided for each transport roller to perform individual control.An electromagnetic brake is provided for each transport roller in order to reduce loads to the motor in comparison with a mechanical brake.

MX3501N Service Manual [7] ADJUSTMENTS

1. Levelness adjustmentThis adjustment is needed in the following situations: * The DSPF section has been disassembled.* The DSPF unit has been replaced.1) Close the DSPF unit and check the clearance between the

projections in the front side and the rear side and the SPFglass holding resin surface.

2) Visually check to insure that the clearance A is 1mm or lessand the clearance B is 0mm (in contact).

If the above requirement is not met, do step 3.3) Turn the height adjustment screw to adjust the DSPF front/rear

frame horizontal level.

When the front frame side is higher (clearance B is more than1mm): Turn the height adjustment screw R of the DSPF rearframe clockwise.When the rear frame side is higher (clearance A is more than1mm): Turn the height adjustment screw L of the DSPF rearframe counterclockwise.Repeat steps 2 to 3 until an acceptable result is obtained.

4) After adjustments of A and B, check to insure that the projec-tion on the front right side is in contact with the glass surface ofthe main unit.

2. Skew adjustment (front surface mode)This adjustment is needed in the following situations:* The DSPF section has been disassembled.* When replacing the DSPF unit.* The DSPF unit generates skewed scanned images.1) Create an adjustment chart by printing in duplex mode the self-

print pattern 71 (grid pattern) specified in Simulation 64-1. Make sure that the print grid pattern is almost in parallel withthe paper edges, and apply position marks 'A', 'B', 'C' and 'D' tothe leading and trailing edges of the paper for both front andback sides of the paper.

2) Copy the adjustment chart (created in step 1) to A3 (11" x 17")paper in DSPF duplex mode, and then check the image forskews (Set in the DSPF feed tray so that the mark on theadjustment chart is at the edge). • Check with one of the following methods.

ALL RIGHTS RESERVED.

The PWB’s of this model employs lead-free solder. The “LF” marks indicated on the PWB’s and the Service Manual mean “Lead-Free” solder.

The alphabet following the LF mark shows the kind of lead-free solder.

(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD

When repairing a lead-free solder PWB, use lead-free solder thread.

Never use conventional lead solder thread, which may cause a breakdown or an accident.

Since the melting point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the

exclusive-use soldering iron is recommendable.

(2) NOTE FOR SOLDERING WORK

Since the melting point of lead-free solder is about 220°C, which is about 40°C higher than that of conventional lead solder, and its soldering

capacity is inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This may cause land

separation or may exceed the heat-resistive temperature of components. Use enough care to separate the soldering iron from the PWB when

completion of soldering is confirmed.

Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently.

If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron

tip after completion of soldering work.

If the soldering iron tip is discolored black during soldering work, clean and file the tip with steel wool or a fine filer.
