Step 10 (and 11)

Printer Free Run must be used instead of System Free Run.

- Reason ­In System Free Run mode, the test pattern will not be written on the drum surface
but the actual scanned image will be written. If we use the System Free Run mode in
this step, a blank image (= image of white paper) will made on the drum surface,
causing too much friction between drum and drum cleaning blade.

The following procedure should be added to the transfer roller unit:

A Printer Free Run should be performed after replacing the roller lubricant bar and/or

6. TRANSFER ROLLER UNIT

When completing machine assembly, after changing the roller lubricant bar
and/or the transfer roller, perform steps 3 to 12 of "3.4 INSTALLING A NEW
DRUM". This will cause the new lubricant bar to fully contact the roller. And
also applies the lubricant to the roller surface evenly.

NOTE: 1) If these steps have been done for the new drum, it is unnecessary

to repeat them.

2) If the developer is replaced together with the roller lubricant bar
and/or the transfer roller, the above steps are unnecessary.
(Lubricant is applied to the transfer roller surface during the
developer initialization.)

3) Note that "Printer Free Run" must be used at step 10 of "3.4
INSTALLING A NEW DRUM".

Subject: Fusing Unit Prepared by: N. Kaiya
From: QAC 1st Field Information Dept. Checked by: T. Inoue
Classification:

This RTB explains the countermeasure for the OHP offset problem which was found in our
test with paper containing calcium carbonate (Aussedat Rey AR Color). In addition, the
modification related to the countermeasure is explained.

PROBLEM

OHP sheets get calcium carbonate on the reverse side in the fusing unit. The problem is
evident under the following conditions.

1. When Folex X-356 OHP film is used.

2. Paper containing a large amount of calcium carbonate is used prior to making copies
with OHP film.

3. After a continuous single-color copy run using paper with calcium carbonate (according
to our test, the problem is evident on the OHP film copied after more than 20 single­color A3 copies are made).

CAUSE

The calcium carbonate from the paper is deposited on the surface of the pressure roller
and offset to the back side of the OHP sheet.

The calcium carbonate deposits on the surface of the pressure roller when there is less
silicone oil on the surface of the pressure roller than usual. This condition only exists
after a long series of single-color copies. This is because when making single-color
copies, the sheets of copy paper are fed to the fusing unit with only a small interval
between them. When making full-color copies, the fusing unit idles during four
development cycles, so the pressure roller has sufficient time to receive silicone oil on its
surface.

COUNTERMEASURE

A pressure roller cleaning blade and a pressure roller oil pad will be added in place of the
pressure roller cleaning roller. The pressure roller cleaning roller will be removed. The
pressure roller cleaning blade removes calcium carbonate on the pressure roller. It also
removes excess silicone oil from the pressure roller. The silicone oil applied on the
pressure roller surface prevents the pressure roller cleaning blade from making vibration
noise.

Gear

The addition of cleaning blade and oil pad applies excess load to the pressure roller
which may result in copy quality problems such as mimizu image. To prevent this
problem, gears are added to the front of the hot roller and pressure roller, which provide
drive to the pressure roller. At the same time, the 61Z Gear has been changed to a 62Z
Gear to compensate for the slight increase in the paper speed caused by providing drive
to the pressure roller. To install the gears, the hot roller and the pressure roller have
been modified with interchangeability x/o.

Gear 61z→62z

Newly Added

The screw holding the front fusing lamp holder has been changed to a shorter (M4 x 5)
screw to prevent contact with the hot roller gear. The same screw type has been added to
secure the ball bearing at the front of the hot roller. This is necessary to maintain the
position of the hot roller gear and to ensure meshing with the pressure roller gear.

Modification Cut-in

This modification has been made to the February production run of machines destined for
the European market, since paper with high calcium carbonate content is seen mostly in
the European market. The modification to apply drive to the pressure roller has been
made to all models to minimize the possibility of copy quality problems such as mimizu
image. For the cut-in serial number, please refer to MB No.6.

Replacement Procedure

Pressure Roller Cleaning Blade

1. Remove the two pressure roller cleaning blade springs.

2. Remove the cleaning blade by sliding it out from the pins on the front and rear fusing
unit side frames.

problem related to the nip band is found, please check it against the new standard and
adjust if necessary. However, it may not be possible to achieve the new adjustment
standard with the old pressure spring.
