IMPORTANT SAFETY NOTICES

I

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.

G056/G058 FIRMWARE MODIFICATION HISTORY

DESCRIPTION OF MODIFICATION

• First Mass Production of Machine

• Firmware modified to make corrections for

the German language.

• Does not exist in the field

• Does not exist in the field

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.

DESCRIPTION OF MODIFICATION FIRMWARE

Firmware modified to correct the following:

1. The spelling of the display for Job
Interrupt in prnlog was change from
“Cancelled” to “Canceled” to conform to
Ricoh MIB (standards).

Added the error message “Can not write

NVRAM information”. This message appears

if an error occurs when saving the printer

status data to the NVRAM

Firmware modified to corrects the following:

1. When using Signature level 2 on the

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.

Firmware modified to corrects the following:

⇒

1. SNMP vulnerability

SNMP security vulnerabilities reported
by CERT on Feb.12, 2002 have been
confirmed and fixed through the
PROTOS c06-snmpv1 test suite.

2. Cannot connect to Novell NDS (GFPR

No. RC02010007). The nearest NetWare
Server informs the NIB of the alternate
NetWare Server address, where the
NDS replica is stored, however the NIB
is unable to interpret the message.

3. Firmware corrected so that the LCD

displays “Printer is not ready” when the
printer is not yet in Ready status, e.g.
when the cover is open.
