SYMPTOM:
1) At machine installation or after the developer is replaced, SP66 (TD sensor Initial
Setting) that would usually take about 60 seconds stops after only a few seconds.
2) After a new machine is installed, copies have high ID and/or toner drops onto copies.
This occurs until about 100 copies are made.
CAUSE:
The TD sensor connector (A1905346: Development Unit Harness) which is mounted on
the I/U (Imaging Unit) is not properly connected to the connector of the Development
Relay Board (A1905145). The board is mounted on the rear side plate of the mainframe.
If the service technician does not tighten the knob screw
raised portion of the mainframe front side plate, the TD sensor connector will not be fully
inserted into the receiving connector on the board.
To check whether or not the connection is stable, make some copies and check the
reading of SP55. If the connection is unstable, the SP55 reading will also be unstable (e.g.
71,125,13,17,117,35).

SOLUTION:
I/U installation procedure
1) Insert the I/U into the mainframe.
2) Push the I/U toward the back so that the I/U front side plate (A1902280) remains flush
against the raised portion of the front side plate of the mainframe (see the illustration
below). While holding the unit in this position (pushing on the handle), tighten the knob
screw (A1902320) by hand until the I/U is secure.

CAUSE:
When the 1st and 2nd scanners start to move, part of the light from the 1st scanner is directly sent
to the mirror of the 2nd scanner, as the two scanners are relatively close. This "extra light" received
by the mirror will cause the image to appear lighter. As scanning continues, the 1st scanner
increases to twice the speed of the 2nd scanner, causing the two scanners to get farther and
farther apart. Therefore, less and less light "extra light" reaches the 2nd scanner mirror. This is why
the image is lighter near the leading edge.
SOLUTION:
A shading seal (A2981684) should be attached to ensure proper image density at the leading edge
(when making copies with very light/halftone originals). Because the extra light passes from the
2nd scanner mirror to the photoconductor via the base plate of the optics unit and lens carriage
(A1901682), the seal should be attached to the lower portion of the lens carriage. This will prevent
the extra light from passing between the optic base plate and lens carriage.
This modification will be applied from August 2000 production.
Please see the procedure as shown below.

2. Remove the lens carriage from the optics unit.
Note: Before removing the lens carriage, remove the left scale, the exposure glass
and the lens cover.

SYMPTOM:
The toner supply motor breaks down so that the toner supply system malfunctions.
CAUSE:
The tip of the worm gear on the motor shaft wears out.
SOLUTION:
1) Apply grease to the tip and spiral threads of the present worm gear of the toner supply
motor (P/N A2983371).
Recommended grease:
Part Number Description
A1909002 Grease-CP501 (5 pcs/set)
52039502 Grease-501
- Cosmos No.1
An equivalent grease for plastic can be used instead of the above ones.
Note: Cosmos No.1 grease was applied to the tip and spiral threads of the worm gear at
the motor vendor as of July 2000 production motors onward.
2) Replace the worm gear with a new one (P/N A2983388) and apply grease to the tip and
spiral threads of the gear.
Note: The material of the new worm gear was changed to NW-02 to improve durability,
and it will be applied from the February 2001 production machines onward. We
will issue a modification bulletin (MB) to inform you of the new part number of the
toner supply motor (the motor service part includes the worm gear) and the cut-in
machine serial numbers.
Please do not order the new parts until the MB is issued, as they are not yet in
stock.
