IMPORTANT SAFETY NOTICES

PREVENTION OF PHYSICAL INJURY

1. Before disassembling or assembling parts of the copier 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 needs 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 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.

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.

1. Firmware modified to improve print quality

when image data is printed using the PCL6 driver. NOTE: This occurs only in the following condition.

• When printing image data

• When using the PCL6 driver

2. New feature added in the user mode. “Curl Prevention” mode is added in the user mode. (Curl Prevention: User mode/ Maintenance). Please note that the function of this mode is the same as the “Curl Control” in the printer engine service mode. It lowers the fusing temperature to prevent paper from curling. Advise customer to use this mode when paper jam occurs during duplex rear side printing. NOTE: When this mode is switched on, the “Curl Control” in the service mode is also switched on.

Symptom:

In PCL printing, if data exists over the bottom edge of the printable area, the machine freezes, displaying "Processing" and operation will no longer be possible.

Condition:

Printer driver is not being used Print data exists on the bottom edge of the printable area (at 4.2mm)

Action:

Update the controller firmware.

NetWare Server, the printer does not connect to the NetWare Server.

2. When printing out using a CICS

application from an IBM mainframe (e.g. AS/390), the printer is only able to output one job due to the lpd protocol that is unique to CICS.

3. When 50 or more lpq/lprm commands

(w/arguments) are executed from the time the printer is turned on, the lpd process at the printer side is interrupted and the job is not printed out.
