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.:

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

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.
