ML-xxxx
Description
Dark or blurry black or white spots occur periodically.
Check
1. Developer cartridge
2. Transfer voltage
3. Transfer roller’s life
Cause
1. If dark or blurry black spots occur periodically, the rollers in the Developer may be contaminated
with foreign matter or paper particles.
(Charge roller : 37 mm interval, OPC drum : 94 mm interval).
2. If faded areas or voids occur in a black image at intervals of 94 mm, or black spots occur
elsewhere, the OPC drum surface is damaged.
3. If a black image is partially broken, the transfer voltage is abnormal or the transfer roller’s life has
expired.
Solution
1. Run OPC cleaning to remove excess toner and paper particles on the charge roller and OPC drum.
Repeat 2 or 3 times. Run the self-test. If the same problem persists, replace the developer.
2. Clean the rollers. If problem persists, replace the Developer.
3. The transfer roller guarantees 50,000 sheets printing. If the roller’s life is expired, replace it.

4. Disassembly and Reassembly
4-1. General Precautions on Disassembly
When you disassemble and reassemble components, you must use extreme caution. The close proximity of
cables to moving parts makes proper routing a must. If components are removed, any cables disturbed by the
procedure must be restored as close as possible to their original positions. Before removing any component
from the machine, note the cable routing that will be affected.
Whenever servicing the machine, you must perform as follows:
1. Remove the paper cassette(s), and the print cartridge. Do not expose the cartridge to direct room light or sun
light, and be careful not to scratch the drum surface.
2. Turn the power switch off.
3. Unplug all the cables from the printer.
4. Replace with only an authorized component.
5. Do not force to open or fasten a plastic material component.
6. Be careful no obstacles are included when you reassemble components.
7. When you reassemble components, be careful small size components are located in place.
8. If you turn the machine over to replace some parts, toner or paper particles may contaminate the LSU window. Protect the LSU window with clean paper.
Releasing Plastic Latches
Many of the parts are held in place with plastic latches. The
latches break easily; release them carefully. To remove such
parts, press the hook end of the latch away from the part to
which it is latched.

3-2. Chip Replacement (SMD)
3-2-1. Precautions for Chip Replacement
1. Do not directly touch any portion of the part with
the soldering iron. ICs, especially TSOPs, are easily
damaged by heat.
2. Use care with the soldering iron tip and avoid
rapidly heating parts. Some parts can be damaged
o
by sudden heating. Preheat the part at about 100 C
for several minutes before installing it.
o
3. Use a soldering tip temperature of about 240 C.
For larger parts, use a slightly higher temperature
o
5. Use care not to damage the circuit pattern, especially when desoldering. Because of the many pins,
cleanliness of the pattern is extremely important
after removing an IC.
6. Use care to avoid solder bridges. Remove any
bridges that occur.
7. Position the part carefully. This also affects the soldering operation. Be very precise in positioning the
IC. Soldering opposite pins first holds the IC in
place and makes soldering the other pins easier.
8. Do not reuse removed parts.
(about 280 C).
4. The thin (0.3mm) solder for miniature parts does
not contain adequate flux. Supplementary flux is
thus needed in most cases.
Computer, OA and A/V systems are manufactured
using flux which can be cleaned by water. When
you replace the part or when troubleshooting, use
proper flux and solder which can be cleaned by
water.
Improper flux may cause the soldering area to corrode and may cause a fatal system error.
3-2
9. Clock for solder joints, especially miniature parts
with small lead.
10. A defective trimming resistor cannot be adjusted
externally. Replace with an ordinary variable resistor.
11. Always inspect the work with a magnifying lens.
Check after installing cold solder joints, etc.

Precautions
1-2. Servicing Precautions
Note: Requirements for AC power are described on the label affixed to the rear of the printer. Check the AC
voltage rating requirement before use.
1. Before disassembly, pull the power plug from the AC
power connector.
2. To avoid spilling toner inside the machine, do not turn
the printer over or on its side before removing the
developer cartridge.
3. Faulty installation of DRAMs may cause permanent
damage to the Laser Printer.
4. Use only+5V power for video controller-related circuitry.
5. When replacing parts, use only the same type of part
as the original. Replacing components with a second
vendor’s part may cause faulty operation.
6. Check the insulation between the blades of the AC
plug and accessible conductive parts (examples : metal
panels and input ports).
7. Insulation Checking Procedure:
Disconnect the power cord from the AC power source.
Connect an insulation resistance meter (500V) to the
blades of the AC plug.
The insulation resistance between each blade of the
AC plug and accessible conductive parts (see left)
should be greater than 1 megaohm.
8. Never defeat any of the B+ voltage interlocks. Do not
apply AC power to the unit (or any of its assemblies)
unless all solid-state heat sinks are correctly installed.
9. Always connect a test instrument’s ground lead to the
instrument chassis ground before connecting the positive lead; always remove the instrument’s ground lead
last.
1-3. ESD Precautions
Some semiconductor (“solid state”) devices are easily damaged from static electricity. Such components commonly are called Electrostatically Sensitive Devices (ESDs); examples include integrated circuits (ICs), LargeScale Integrated circuits (LSIs), some field-effect transistors, and semiconductor chip components. The following techniques will reduce the occurrence of component damage caused by static electricity:
CAUTION: Be sure the power is off to the
chassis or circuit board, and
observe all other safety precautions
1. Immediately before handling any semiconductor components assemblies, drain the electrostatic charge from
your body by touching a known earth ground.
Alternatively, wear a discharging wrist strap device.
(Be sure to remove the strap before applying power to
the unit under test to avoid potential shock.)
2. After removing ESD-equipped assembly, place it on a
conductive surface such as aluminum foil to prevent
accumulation of an electrostatic charge.
3. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ESDs.
4. Use only a ground-tip soldering iron when soldering
or desoldering ESDs.
5. Use only anti-static solder removal device. Some solder removal devices are not rated as “anti-static;”these
can accumulate sufficient electrical charge to damage
ESDs.
1-2
6. Do not remove a replacement ESD from its protective
package until you are ready to install it. Most replacement ESDs are package with leads that are electrically
shorted together by conductive foam, aluminum foil
or other conductive materials.
7. Immediately before removing the protective material
from the leads of a replacement ESD, touch the protective material to the chassis or circuit assembly into
which the device will be installed.
8. Minimize body motions when handling unpackaged
replacement ESDs. Motion such as your clothes brushing together, or lifting a foot from a carpeted floor can
