Safety Notices
Important Safety Notices
Prevention of Physical Injury
1. Before disassembling or assembling parts of the machine and peripherals, make sure that the machine
power cord is unplugged.
2. The wall outlet should be near the machine and easily accessible.
3. 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.
4. The machine drives some of its components when it completes the warm-up period. Be careful to keep
hands away from the mechanical and electrical components as the machine starts operation.
5. The inside and the metal parts of the fusing unit become extremely hot while the machine is operating.
Be careful to avoid touching those components with your bare hands.
Health Safety Conditions
Toner is 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 machine and its peripherals must be serviced by a customer service representative who has completed
the training course on those models.
• The Controller board on 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
recommended by the manufacturer. Discard batteries in accordance with the manufacturer's
instructions and 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, the maintenance unit which includes developer or the organic photoconductor
in accordance with local regulations. (These are non-toxic supplies.)

3. Dispose of replaced parts in accordance with local regulations.
• To prevent a fire or explosion, keep the machine away from flammable liquids, gases, and aerosols.
A fire or an explosion might occur.
Handling Toner
• Work carefully when removing paper jams or replacing toner bottles or cartridges to avoid spilling
toner on clothing or the hands.
• If toner is inhaled, immediately gargle with large amounts of cold water and move to a well ventilated
location. If there are signs of irritation or other problems, seek medical attention.
• If toner gets on the skin, wash immediately with soap and cold running water.
• If toner gets into the eyes, flush the eyes with cold running water or eye wash. If there are signs of
irritation or other problems, seek medical attention.
• If toner is swallowed, drink a large amount of cold water to dilute the ingested toner. If there are signs
of any problem, seek medical attention.
• If toner spills on clothing, wash the affected area immediately with soap and cold water. Never use
hot water! Hot water can cause toner to set and permanently stain fabric.
• Always store toner and developer supplies such as toner and developer packages, cartridges, and
bottles (including used toner and empty bottles and cartridges) out of the reach of children.
• Always store fresh toner supplies or empty bottles or cartridges in a cool, dry location that is not
exposed to direct sunlight.
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.
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.

Machine Installation
Main Unit and Option Unit
Refer to the "Hardware Guide" for M041 model about the machines installation.
Printer Option
Refer to the "Hardware Guide" for M041 model about the machines installation. If more than two optional
applications are supposed to be installed, do "SD Card Appli Move" described below.
• IPDS option requires an optional memory (128 MB or 256 MB). Install an optional memory first
before installing the IPDS option. Otherwise, the machine may stall when large print job data is sent
to the machine.
SD Card Appli Move
Overview
The service program "SD Card Appli Move" (SP5-873) lets you to copy application programs from one
SD card to another SD card.
Slot 1 and Slot 2 are used to store application programs. However, more than two optional applications
are supplied for this machine. In that case, you can move application programs from Slot 2 to Slot 1 with
the following procedure.
Obey these precautions during the SD Card Appli move procedure:
• The authentication data is moved with the application program from an SD card to the other SD card.
Authentication fails if you try to use the SD card after you move the application program from this card
to another SD card.
• Do not use an SD card if it has been used for some other work, for example, on a computer. Normal
operation is not guaranteed when such SD card is used.
• Store the original SD card in a safe location after the procedure. The original SD card cannot be used
but it must be saved because (1) the original card is the only proof that the user is licensed to use the
application program, and (2) you may need to check the SD card and its data to solve a problem in
the future.

Move Exec
"Move Exec" (SP5873 1) moves application programs from the original SD card to another SD card. The
application programs are moved from Slot 2 to Slot 1.
1. Turn off the main power switch.
2. Remove the SD card slot cover [A] ( x 1).
3. Insert the original SD card with the application in Slot 2 [B] (lower slot).
4. Insert the SD card to receive the application in Slot 1 [C] (upper slot).
5. Turn on the main power switch.
6. Enter the SP mode and do SP5873 1 "Move Exec."
7. Follow the messages on the operation panel to complete the procedure.
8. Exit the SP mode.
9. Turn off the main power switch.
10. Remove the original SD card from Slot 2.
11. Leave the other SD card in Slot 1.
12. Turn on the main power switch.
13. Confirm that the application program runs normally.
14. Tell the customer to store the original SD card in a safe place.
