Symptom

The printed image shifts to left when printing from the optional paper feed unit.
The image is printed in the correct position when printing from the standard paper tray.

Cause

The initial value of the print left margin was fixed during the pre-mass-production.
However, the mechanical unit shifted the print left margin during the mass-production.
The print left margin for the standard paper tray was adjusted in the assembly line, but the
print left margin of the optional paper feed unit was not adjusted.

Countermeasure

The initial value of the print left margin for the standard paper tray and the optional paper
feed unit will be changed in order to match the mechanical unit. This change will be
implemented from the January production runs.

Action required

If the user makes a complaint about the print left margin from the optional paper feed unit,
adjust the print left margin for the optional paper feed unit by referring to the following
table.

Symptom

The scanner bottom margin is wider by a few millimeters.

Cause

A sheet has been added to the scanner cover to accurately reset the document exit
sensor starting from the November 1996 production run.

(H5291156:Sheet - Scanner Cover)

As a result, the document exit sensor resets accurately and quickly.
It may cause a wider blank space at the bottom of the scanned pages and the
omission of the trailing edges of the scanned pages.

Countermeasure

If the scanner bottom margin is too wide, please change the following RAM data.
Address Value
800298 10 → 16 (Copy Mode 100%)
804D67 00 → 07 (Memory Tx STD)
804D69 0B → 11 (Copy Mode 75%)

804D73 1F → 1E (Memory Tx SSF)
804D75 07 → 00 (Memory Tx STD)
Note: Do not change the above RAM values on the machines in which the Scanner

Cover Sheet was not added.

SYMPTOM

The Document Pick-up Solenoid stays on even after document is fed out and this
causes overheating . This may result in warping of the operation panel cover and
damage to transistor Q4 on the FCU.

CAUSE

There is no software protection for the above condition.
This may happen if an original is fed in too far between the Document Pick-up
Roller and Separation Pad, but it is rare.

SOLUTION

1) Software Update
H5287120E for FX7, H5297120C for LX7

2) Adding a decal informing users not to forcibly insert documents (Under
preparation :The decal should be expectedly available at the beginning of March

1997)

SYMPTOM

When the drum cartridge is replaced, if the top cover is not opened fully, paper jams will
occur.

CAUSE

The drum cartridge gear comes off if the top cover is not opened fully.

SOLUTION

Instruct the customer to repair the drum cartridge gears in the following manner

1. Remove drum cartridge gear-1 from the drum cartridge.

2. Snap on drum cartridge gear-1 in the correct position.

3. Instruct the customer to open the top cover fully when installing the drum
cartridge.

We will prepare the drum cartridge gear as a service part. If the customer breaks the drum
cartridge gear by mistake, use a new one.

SYMPTOM

A document jam error occurs even though there are no documents in the ADF. This is

because the Document Sensor is stuck.

CAUSE

The actuator of the document sensor touches the sensor unit on the Scanner Sensor

Board.

I

From September, the scanner sensor board was shifted to the left during assembly,
However, the board might be shifted due to vibration during transportation.

From December, the document sensor actuator was changed to prevent contact with

the sensor.

the end of the last page of the document.
