1. Before You Begin
About This Manual
If the machine will not print, does not print as expected, or exhibits any other problem, find the problem
in this manual and troubleshoot accordingly.
• Before you replace any unit:
• To prevent electrical shock, turn off the printer controller on the machine control panel,
switch off the main power switch then the AC power switch, and then disconnect the
machine from the power supply.
• Allow the machine to cool for at least 30 minutes before replacing a part.

Guide to Components
• Do not remove any covers or screws other than those explicitly mentioned in this manual. Inside
this machine are high voltage components that are an electric shock hazard and laser
components that could cause blindness. Contact your sales or service representative if any of the
machine's internal components require maintenance, adjustment, or repair.
• Do not attempt to disassemble or modify this machine. Doing so risks burns and electric shock.
Note again that exposure to the laser components inside this machine risks blindness.

2. Troubleshooting Service Call
Problems (SC Codes)
What Are SC Codes?
If an error occurs during operation, the machine displays an SC code ("SCnnn", where "nnn" is a three-
digit number). The machine stops and cannot be used when an SC code is displayed.
If an SC code appears:
1. Write down the SC number.
2. Turn off the main power switch.
3. Wait a few moments, then turn the machine on again.
In most cases, cycling the machine off and on will restore it to full operation.
4. If the SC code reappears, check it against the SC code table. For details, see page 16
"SC Code List".
Check for the SC code in the table.
If the SC code is listed in the table, carry out the recommended procedure.
If the SC code is not listed in the table, contact your service representative.
15

SC Code List
This table contains a list of selected SC codes. If the SC code that is displayed on the control panel is
listed in this table, carry out the recommended procedure. If the SC Code is not listed in this table,
contact your service representative.
• If the error persists after replacing the unit, contact your service representative.
Code Error Procedure
332-01 Toner supply motor 1 error (left bottle) Check that toner supply motor 1 operates
properly.
332-05 Toner supply motor 2 error (right bottle) Check that toner supply motor 2 operates
properly.
336-01 Developer imperfect setting (K) Check the developer.
410-01 Remaining potential: Vr detection error (K) Replace the photoconductor unit.
411-01 Charge potential: Vd adjustment error (K) Replace the charge unit.
412-01 Exposure potential: Vpl adjustment error (K) Replace the charge unit.

3. Troubleshooting Image Quality
Problems
Toner Spotting/Staining
Paper Is Spotted with Toner
Paper is soiled with toner spots of 0.5–1 mm (0.02–0.04 inches) in diameter.
CEZ538
Cause:
Toner fragments have slipped through the cleaning web, which cleans the pressure roller, and re-
adhered to paper.
This may occur if:
• Printing on both sides of paper
• Printing on uncoated (especially rough-textured) paper
• Printing a single-dot halftone image
• To adjust the following settings, pre-register the type of paper in use as a custom paper. For details
about registering custom papers, see "Registering a Custom Paper", Preparation.
17

Solution:
Increasing the temperature when using thin paper with a thickness equivalent to Paper Weight 0 or 1
may cause paper curling, resulting in paper jams at the fusing unit. Carry out steps from Step 6 when
using thin paper with a thickness equivalent to Paper Weight 0 or 1.
1. In [Advanced Settings] for the custom paper in use, select 1206: [Fusing Temperature],
and then increase the temperature by 5 degrees in [Heat Roller Temp].
2. Print the image. Is the problem resolved?
Yes Finished!
No Go to the next step.
3. Increase the temperature an additional 5 degrees in [Heat Roller Temp].
4. Print the image. Is the problem resolved?
Yes Finished!
No Go to the next step.
5. Have changes to the settings resulted in glossy lines or paper misfeed?
Yes Decrease the temperature by 10 degrees, and then go to the next step.
No Go to the next step.
6. In [Advanced Settings] for the custom paper in use, select 1209: [Fusing Cleaning], and
then set [Cleaning Interval] to 0.01.
7. Print the image. Is the problem resolved?
Yes Finished!
No No further improvement is likely. Contact your service representative.
• Decreasing the value in [Cleaning Interval] will shorten the replacement cycle of the cleaning web.
Black Spots
Black spots appear at 314 mm (12.4 inches) intervals.
