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.

If the front surface copy image is as shown above and theback surface copy is not as shown above, go to the step 3)of "3. Skew adjustment (Back surface mode)."If the above requirement is not met for the paper's front side,then do step 3.
3) Loosen the hinge screws and lower the two attachments.
4) Open the DSPF and loosen the screw.
5) Adjust by turning the DSPF skew adjusting screw on the rightside of the DSPF rear frame.
[When the main scanning direction print line is shifted to theleft]
If a < b, then turn counterclockwise the DSPF skew adjusting screw.
[When the main scanning direction print line is shifted to theright]
If a > b, then turn clockwise the DSPF skew adjusting screw.Repeat steps 2 to 5 until an acceptable result is obtained.
3. Skew adjustment (back 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.

[Check Method 2]Check that the squareness of the main scanning directionprint line for the longitudinal direction of paper is within1.0mm.
If the back surface copy image is as shown above and thefront surface copy is not as shown above, go to the step 3)of "2. Skew adjustment (Front surface mode)."If the back surface copy is not as shown above, perform theprocedures of step 3) or later.
3) Open the upper door, and remove the adjustment cover.
4) Turn the DSPF skew adjustment screw on the CCD unit toadjust.
[When the main scanning direction print line is shifted to theleft]
If c < d, turn the DSPF skew adjustment screw A counterclockwise, or turn the adjustment screw B clockwise.
[When the main scanning direction print line is shifted to theright]
If c > d, turn the DSPF skew adjustment screw A clockwise,or turn the adjustment screw B counterclockwise.
* The adjustment screws A and B must be turned in properbalance. For example, if the trouble is not removed by turn-ing the adjustment screw A 180 degrees clockwise, do notturn the adjustment screw A furthermore, but turn the adjust-ment screw B 180 degrees counterclockwise.
Repeat steps 2 to 5 until an acceptable result is obtained.
4. Image focus adjustment (front surface mode)
For details of this adjustment, refer to "[6] ADJUSTMENTS" of thecopier Service Manual (00ZMX3500NS1E).
5. Image focus adjustment (back surface mode)
This adjustment is required in the following cases:* When the DSPF CCD unit is replaced.* When the DSPF CCD unit is replaced.* When the COPY/SCAN/FAX image focus is not properly
adjusted.* When the DSPF unit is removed.* When the DSPF unit is replaced.1) Make a duplex copy in DSPF mode.2) Make sure that the copied image on the back side of the paper
is satisfactorily focused.If the image is not satisfactorily focused, do the followingsteps.
3) Open the door. Remove the screws, and remove the transportPG upper.
4) To prevent against shift of the CCD unit optical axis, mark theCCD unit base as shown below.

MX3501N ADJUSTMENTS 7 – 3
5) Loosen the CCD unit fixing screws (4 pcs.).
* Never loosen the screws marked with ✕.Loosening these screws could possibly change the CCDunit base optical axis. Once the optical axis has beenchanged, it cannot be corrected through on-site adjust-ments. Solving such a problem requires the replacement ofthe entire scanner unit.
6) Slide the CCD unit in the arrow direction (CCD sub scanningdirection) to change the installing position.When the copy image is longer than the original scale, shift theCCD unit in the direction B. When the copy image is shorterthan the original scale, shift the CCD unit in the direction A.One scale of mark-off line corresponds to 0.2%.At that time, fix the CCD unit so that it is in parallel with thescale on the front and the rear side of the CCD unit base.* Fix the CCD unit so that it is in parallel with the line marked
in procedure 4).
7) Make a copy and check the copy magnification ratio again.If the copy magnification ratio is not in the range of 100 ± 1%,repeat the procedures of 4) – 6) until the condition is satisfied.
NOTE: By changing the CCD unit fixing position with the simula-tion 48-1 adjustment value at 50, the copy magnificationratio is adjusted within the specified range (100 ± 1.0%)and the specified resolution is obtained based on the opti-cal system structure.
6. Image magnification in the main scanning direction adjustment (front surface mode)
For details of this adjustment, refer to "[6] ADJUSTMENTS" of thecopier Service Manual (00ZMX3500NS1E).
7. Image magnification in the main scanning direction adjustment (back surface mode)

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.
