1-2. PRECAUTIONS FOR HANDLING THE LASER EQUIPMENT
•
The laser used in this copier is a semiconductor laser having the following specifications.
Max. power: 5mW Output wavelength: 770~80nm
•
When laser protective goggles are to be used, select ones with a lens conforming to the above specifications.
•
When a disassembly job needs to be performed in the laser beam path, such as when working around the printerhead and PC Drum, be sure first to turn the copier OFF.
•
If the job requires that the copier be left ON, take off your watch and ring and wear laser protective goggles.
•
A highly reflective tool can be dangerous if it is brought into the laser beam path. Use utmost care when handling tools on the user’s premises.
•
The printerhead is not maintainable in the field. It is to be replaced as an assembly including the control board. Never, therefore, attempt t o remo ve the laser diode or adjust trimmers on the control board.

1-3. INSTRUCTIONS FOR HANDLING THE PWBs WITH MOS ICs
The following precautions must be observed when handling P.W. Boards with MOS (Metal Oxide Semiconductor) ICs.
During Transportation/Storage:
•
During transportation or when in storage, new P.W. Boards must not be indiscriminately removed from their protective conductive bags.
•
Do not store or place P.W. Boards in a location exposed to direct sunlight.
•
When it becomes absolutely necessary to remove a Board from its conductive bag or case, always place it on its conductive mat in an area as free as possible from static elec­tricity.
•
Do not touch the pins of the ICs with your bare hands.
During Replacement:
•
Before unplugging connectors from the P.W. Boards, make sure that the power cord has been unplugged from the outlet.
•
When removing a Board from its conductive bag or conductive case, do not touch the pins of the ICs or the printed pattern. Place it in position by holding only the edges of the Board.
•
Before plugging connectors into the Board, make sure that the power cord has been unplugged from the power outlet.
During Inspection:
•
Avoid checking the IC directly with a multimeter; use connectors on the Board.
•
Never create a closed circuit across IC pins with a metal tool.
•
When it is absolutely necessary to touch the ICs and other electrical components on the PW Board, be sure to ground your body.
1-4. HANDLING OF THE IMAGING CARTRIDGE
During Transportation/Storage:
•
Use the specified carton whenever moving or storing the Imaging Cartridge.
•
The storage temperature is in the range between –20°C and +40°C.
•
In summer, avoid leaving the Imaging Cartridge in a car for a long time.
Handling:
•
Ensure that the correct Imaging Cartridge is used.
•
Store the Imaging Cartridge in a site that is not exposed to direct sunlight.
Precautionary Information on the PC Drum Inside the Imaging Cartridge:
•
The PC Drum exhibits greatest light fatigue after being exposed to strong light over an extended period of time. Never, therefore, expose it to direct sunlight.
•
Use care not to contaminate the surface of the PC Drum with oil-base solvent, finger­prints, and other foreign matter.
•
Do not scratch the surface of the PC Drum.
•
Do not apply chemicals to the surface of the PC Drum.
•
Do not attempt to wipe clean the surface of the PC Drum.

1-5. PARTS WHICH MUST NOT BE TOUCHED
(1) Red painted Screws
Purpose of Application of Red Paint
Red painted screws show that the assembly or unit secured can only be adjusted or set at the factory and should not be readjusted, set, or removed in the field.
Note that when two or more screws are used on the part in questions, only one representa­tive screw may be marked with red paint.
(2) Variab le Resistors on Board
Do not turn the variable resistors on boards for which no adjusting instructions are given in “ADJUSTMENT.”
(3) Other Screws
Although not marked with red paint, the following screws must not be loosened or read­justed.
8 screws on the PH Unit Cover

4-2. REMOUNTING THE EEPROM (IC3A)
NOTES
•
If the Imaging Cartridge is not to be replaced after the Master Board has been replaced with a new one, be sure to remount the EEPROM (IC3A) from the old to new Master Board.
•
If the Master Board has been replaced with a new one and the EEPROM (IC3A) has not been remounted, be sure to replace the Imaging Cartridge with a new one. Because the EEPROM contains no data in this case, make settings and readjustments as necessary.
1. Remove the Master Board. (For details, see 2-2. REMOVAL OF CIRCUIT BOARDS AND OTHER ELECTRICAL COMPONENTS.)
2. Demount the EEPROM (IC3A) from the new Master Board.
