IMPORTANT SAFETY NOTICES

PREVENTION OF PHYSICAL INJURY

1. Before disassembling or assembling parts of the printer and peripherals, make sure that the printer power cord is unplugged.

2. The wall outlet should be near the printer and easily accessible.

3. Note that some components of the printer and the paper tray unit are supplied with electrical voltage even if the main power switch is turned off.

4. If any adjustment or operation check has to be made with exterior covers off or open while the main switch is turned on, keep hands away from electrified or mechanically driven components.

5. The inside and the metal parts of the fusing unit become extremely hot while the printer is operating. Be careful to avoid touching those components with your bare hands.

HEALTH SAFETY CONDITIONS

Toner and developer are non-toxic, but if you get either of them in your eyes by accident, it may cause temporary eye discomfort. Try to remove with eye drops or flush with water as first aid. If unsuccessful, get medical attention.

OBSERVANCE OF ELECTRICAL SAFETY STANDARDS

1. The printer and its peripherals must be installed and maintained by a customer service representative who has completed the training course on those models.

2. The NVRAM on the system control board has a lithium battery which can explode if replaced incorrectly. Replace the NVRAM only with an identical one. The manufacturer recommends replacing the entire NVRAM. Do not recharge or burn this battery. Used NVRAM must be handled in accordance with local regulations.

SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL

1. Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly when exposed to an open flame.

2. Dispose of used toner, developer, and organic photoconductors in accordance with local regulations. (These are non-toxic supplies.)

3. Dispose of replaced parts in accordance with local regulations.

4. When keeping used lithium batteries in order to dispose of them later, do not put more than 100 batteries per sealed box. Storing larger numbers or not sealing them apart may lead to chemical reactions and heat build-up.

Page 22

LASER SAFETY

The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based optical units in the field. The optical housing unit can only be repaired in a factory or at a location with the requisite equipment. The laser subsystem is replaceable in the field by a qualified Customer Engineer. The laser chassis is not repairable in the field. Customer engineers are therefore directed to return all chassis and laser subsystems to the factory or service depot when replacement of the optical subsystem is required.

WARNING Use of controls, or adjustment, or performance of procedures other than those specified in this manual may result in hazardous radiation exposure.

WARNING WARNING: Turn off the main switch before attempting any of the procedures in the Laser Unit section. Laser beams can seriously damage your eyes.

Lithium Batteries (Memory Back-up)

CAUTION The danger of explosion exists if a battery of this type is incorrectly replaced. Replace only with the same or an equivalent type recommended by the manufacturer. Discard used batteries in accordance with the manufacturer’s instructions.

GENERAL CAUTIONS

3. REPLACEMENT AND ADJUSTMENT

3.1 GENERAL CAUTIONS

CAUTION To avoid damage to the transfer belt, drum, or development unit when it is removed or re-installed, never turn off either power switch while electrical components are active.

CAUTION Turn off the main power switch and unplug the machine before attempting any of the procedures in this section.

3.1.1 LASER UNIT

1. Do not loosen the screws that secure the LD drive board to the laser diode casing. Doing so would throw the LD unit out of adjustment.

and

Adjustment

Replacement

2. Do not adjust the variable resistors on the LD unit, as they are adjusted in the factory.

3. The polygon mirror and F-theta lenses are very sensitive to dust. Do not open the optical housing unit.

4. Do not touch the glass surface of the polygon mirror motor unit with bare hands.

5. After replacing the LD unit, do the laser beam pitch adjustment. Otherwise, an SC condition will be generated.

3.1.2 USED TONER

1. Dispose of used toner in accordance with local regulations. Never throw toner into an open flame, for toner dust may ignite.

SM 3-13 G065

LASER UNIT

Laser Beam Pitch Adjustment

After replacing the LD board, do the laser beam pitch adjustment. There are two procedures: one for 400 dpi, and one for 600 dpi. These use the following SPs.

SP2110 Test Mode Dpi (0: 400 dpi, 8: 600 dpi) SP2109-01 LD Beam Pitch Adjustment – 400 dpi SP2109-02 LD Beam Pitch Adjustment – 600 dpi SP2109-03 LD Beam Pitch Adjustment – 400 dpi Initial Setting SP2109-04 LD Beam Pitch Adjustment – 600 dpi Initial Setting

NOTE: If you do not have an SMC Report for reference, print the SMC Report so

you can look up and match the SP numbers below with the correct name.

1. Set SP2110 to 0 (for 400 dpi), or to 8 (for 600 dpi).

2. Execute SP2109-08 to reset all the beam pitch data.

3. For SP2109-01 input 144. NOTE: The entry “144” is only a starting reference value that will allow the

machine to operate. It is only a starting point for adjustment.

4. Execute SP2109-03.

5. Print the test pattern onto A3 (11" x 17") paper using SP2902-03 no.15. (☛ 5 Service Tables, 5.1.2 Test Pattern Printing (SP2902).

6. On the test pattern write 144, the value of SP2109-01.

7. Change the value of SP2109-01 and then print another test pattern, repeating steps 2 to 6. Print about 5 patterns with different values for SP2109-01 (e.g. 48, 96, 192, 240).

8. Check these test patterns. If the laser beam pitch is not correct, the image looks like a black vertical stripe pattern (see the diagrams below). NOTE: For example, if the pattern made with the value 192 has fewer obvious

stripes than the other printouts, the correct value is near 192.

9. Fine adjustment: Do steps 2 to 6 to adjust the laser beam pitch position until thin lines are of uniform thickness (no stripes should appear on the printout). NOTE: In step 3, input a value estimated to be correct (e.g., if 192 was the

closest, try 182), then do steps 4 and 5, then if necessary go back to step 2 and try another value.

10. After adjusting the laser beam pitch for 400 dpi, adjust it for 600 dpi, using the same procedure as for 400 dpi (use the SP modes for 600 dpi). Laser beam pitch for 600 dpi should be 24 ~ 48 more than for 400 dpi.

Assembly

1. With the PCU slightly offset, set it on top of the development unit, then carefully slide it horizontally to ensure that the end of the toner supply shutter at the toner supply port opens.

2. Check the exposed spring on the back of the PCDU.

• If the spring is spread open, the supply port is open.

• If the spring is not open, the supply port is shut. Slide the PCU back and

engage it correctly.

NOTE: If the supply port remains closed, no toner will reach the drum.
