Technical Bulletin PAGE: 2/3

Model: Model K-P1 Date: 18-Jan-01 No.: RG058001

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)

4.2

Printable area

The problem occurs only if

data exists on the bottom

edge (4.2mm) of the printable

area .

4.2

Action:

Update the controller firmware.

1.05

Firmware modified to make corrections in the German wording. 1.02

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.”

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

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:

Configuration Page

Host Interface

xxxxx

PCL Menu

xxxxx

System Reference

Paper Input

System

Paper Feed Directon

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.

Technical Bulletin PAGE: 3/3

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.
