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.
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)

Firmware Updating Procedure
1. Prepare 2 IC cards with the controller firmware.
2. Turn off the main switch.
3. Remove the IC card slot cover on the rear side of the machine as shown.
4. Insert IC card 1 and turn on the main switch.
“Onboard Sys. 1/2” is displayed.
5. Press “# Enter.”
Note: Make sure that ∗is displayed.
6. Scroll with the [▲] [▼] key and select “Update.”
Press “# Enter” to start downloading.
The “On Line” LED starts blinking and the machine starts to
download the program.
(Notice that the ∗mark disappears as the program is
downloaded.)
7. When updating with card 1 is finished, “Update 1/2 task done”
is displayed.
8. Turn off the main switch and replace the card with IC card 2.
Turn on the main switch, then downloading will automatically
start.
9. When updating with card 2 is finished, “Update done” is
displayed.
Then, remove the card, turn on the main switch and print the
configuration sheet.
Check that controller firmware is successfully updated.

Change Descriptions
Descriptions Version
No changes from previous version (only carryover items for Japanese domestic
version). 1.11
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 by-
pass feeding. Firmware modified so that the adjustment is applied to all paper
sources.
1.09
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. 1.08

SYMPTOM
Dirty background may occur at installation, either on the right side or throughout the
printout. The following is an example of dirty background on the right side with A4/LT LEF:

Technical Bulletin PAGE: 2/3
Model: Model K-P1 Date: 09-Apr-01 No.: RG058003
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.
1234
Developer accumulates on
left side of the cartridge.
1234
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.

Model: Model K-P1 Date: 09-Apr-01 No.: RG058003
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.

NOTE: 1) Do not remove the screws that secure the LD board.
2) Do not touch any variable resistors on the LD board.
When installing the LD Unit:
Tighten the screw [C] until the unpainted portion of the screw [F] is not visible.
After installing the LD unit, check the test pattern for the final adjustment (see the following
procedure).
