Descriptions of the changes

Descriptions Version

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 “Curl Control” in the
printer engine service mode.
It lowers the fusing temperature to prevent paper from curling. Advise
customers to use this mode when paper jams occur during duplex rear side
printing.
Note: When this mode is switched on, “Curl Control” in the service mode is
also switched on.

Firmware modified to correct the following problem.

No.:

RG058001

Symptom:

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

Condition:

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

Change Descriptions

Descriptions Version

No changes from previous version (only carryover items for Japanese domestic
version).
Firmware modified to correct the following:

•

The machine was showing SC 546 when the symptom was SC 541.

•

Duplex backside (leading edge) registration adjustment was applied only to by­pass feeding. Firmware modified so that the adjustment is applied to all paper
sources.

The engine process timing is changed to further ensure that waste toner tank
overflow does not occur when the machine is used under low duty.

CAUSE

Dirty background on the right side:

The developer will shift to the left side if the cartridge is tilted as shown below when the
sealing tapes are being removed. This causes toner to be over-supplied on the right side
of the cartridge, which in turn causes the dirty background on the right side of the printout.

Developer accumulates on
left side of the cartridge.

1 2 3 4

1 2 3 4

When removing the tape, place the
machine on a level surface.

Dirty background throughout the page:

This may occur when the user turns on the main switch without removing the tape seals or
when the cartridge has been shaken after the seals are removed.

The position of the toner agitator is adjusted at the factory. When the main switch is turned
on, the main motor turns the agitator. Then, when the user actually removes the seals and
resets the cartridge in the machine, the agitator is no longer in the proper position, and this
causes dirty background on the printouts.

If the cartridge is shaken after the tape seals are removed, dirty background may occur as
the developer is not evenly distributed in the development unit.

SOLUTION

This symptom may only occur at installation. If it should occur, please advise customers to
print out 30 to 40 pages. In most cases, the symptom will gradually disappear.

In addition, as a preventative measure, please advise customers to be sure and do the
following:

• Remove the seals before turning on the main switch.

• Place the cartridge on a level surface when removing the seals.

• Once the seals have been removed, do not shake the cartridge.

Note: This only applies to cartridge installation and replacement.

From March 2001 production, the following changes were applied to alert customers to
these points.

• Strips of yellow tape have been added that will stick out of the machine, calling

attention to the user to remove the tape seals inside before turning on the main switch.

• A label and caution sheet have been added cautioning the user not to tilt the cartridge

when removing the seals.

The cartridge has been modified from June production so that dirty background will not
occur at installation even when the cartridge is tilted.

A green decal is added so the new cartridge can be distinguished from the old type.
The same decal is also placed on the supply cartridge, next to the bar-code label on the
box.

This RTB is to remind you of the remarks for cartridge installation.

• Place the cartridge on a level surface when removing the sealing tapes on the
cartridge.

• Remove the sealing tapes on the cartridge before turning on the main switch.

• Once the seals have been removed, do not shake the cartridge.

Note: This only applies to cartridge installation and replacement.

Please refer to the original RTB, which was previously issued for the dirty background
problem at installation.
