Safety, Conventions
Safety
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.
6. To prevent a fire or explosion, keep the machine away from flammable liquids, gases, and
aerosols.
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
The printer and its peripherals must be installed and maintained by a customer service
representative who has completed the training course on those models.
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.
The controller board in this machine contains a lithium battery.
The danger of explosion exists if a battery of this type is incorrectly replaced. Replace
only with the same or an equivalent type of battery recommended by the manufacturer.
Dispose of batteries in accordance with the manufacturer's instructions and local laws
and regulations.
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.
Use of controls, or adjustment, or performance of procedures other than those
specified in this manual may result in hazardous radiation exposure.
Turn off the main switch before attempting any of the procedures in the Laser Unit
section. Laser beams can seriously damage your eyes.

2.3.3 SD CARD APPLICATION MOVE
The PostScript3 application and fonts cannot be moved to another SD card. However,
other applications can be moved onto the PostScript3 SD card.
Overview
The service program "SD Card Appli Move" (SP5-873) lets you copy application programs from
one SD card to another SD card.
Slot 1 (Upper) is used to store application programs. But there are 3 possible applications
(PostScript 3, DOS (DataOverwriteSecurity) unit, PictBridge). You cannot run application
programs from Slot 2 (Lower). However you can move application programs from Slot 2 (Lower)
to Slot 1 (Upper) with the following procedure.
Make sure that the target SD card has enough space.
1. Enter SP5873 "SD Card Appli Move".
2. Then move the application from the SD Card in Slot 2 (Lower) to the SD Card in Slot 1
(Upper).
Do steps 1 - 2 again if you want to move another application program.
3. Exit the SP mode.
Be very careful when you do the SD Card Appli Move procedure:
The data necessary for authentication is transferred with the application program from an
SD card to another SD card. Authentication fails if you try to use the SD card af ter you copy
the application program from one card to another card.
Do not use the SD card if it has been used before for other purposes. Normal operation is

not guaranteed when such an SD card is used.
Keep the SD card in a safe place after you copy the application program from one card to
another card. This is done for the following reasons:
1) The SD card can be the only proof that the user is licensed to use the application
program.
2) You may need to check the SD card and its data to solve a problem in the future.

4.1 GENERAL PRECAUTIONS
4.1.1 PRECAUTIONS ON DISASSEMBLY
Always turn off the main power switch and unplug the machine before attempting any
of the procedures in this section.
Use extreme caution when removing and replacing components. The cables in the machine are
located very close to moving parts; proper routing is a must.
After components have been removed, any cables that have been displaced during the
procedure must be restored as close as possible to their original positions. Before removing any
component from the machine, note any cable routings that may be affected.
Before servicing the machine:
1. Verify that documents are not stored in memory.
2. Remove the print cartridge before you remove parts.
3. Unplug the power cord.
4. Work on a flat and clean surface.
5. Replace with authorized components only.
6. Do not force plastic material components.
Make sure all components are returned to their original positions.
Laser Unit
1. Do not loosen or adjust the screws securing the LD drive board on the LD unit. Doing so will
throw the LD unit out of adjustment.
2. Do not adjust the variable resistors on the LD unit, as these are permanently adjusted at
the factory. If replacement of the LD drive board is necessary, replace the entire LD unit.
3. Keep the polygon mirror and toroidal lens free of dust. Laser performance is very sensitive
to dust on these components.
4. Do not touch the shield glass or the surface of the polygon mirror with bare hands.
5. Do not adjust the Laser Synchronization detector on the LD unit, as these are permanently
