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.
Note that some components of the printer and the paper tray unit are supplied with electrical
3.
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.)
Dispose of replaced parts in accordance with local regulations.
3.

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.

•
The SD card supplied with the optional hard disk (M020 model only) can be used in either of the
two slots.
5. Reattach the cover over the SD card. Fasten the screw to secure the cover.
• Do not touch the card while the printer is in use. It may come loose, even if pushed only slightly. The
slot cover must be reattached.
• You can confirm that the SD card was installed correctly by checking the control panel menu.
Depending on the SD card, certain menu items appear on the display.
SD card supplied with the optional hard disk (M020 model only): Make sure [Machine Data
•
Encryption] appears in [Security Options]. Depending on settings, [Machine Data Encryption]
might not appear. For details about how to confirm this setting, consult your administrator.

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".
Then move the application from the SD Card in Slot 2 (Lower) to the SD Card in Slot 1 (Upper).
2.
• 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 after 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.
Move Exec
The menu "Move Exec" (SP5873-001) lets you copy application programs from the original SD card to
another SD card.
