SUBJECT: TONER SPILL FROM THE DEVELOPMENT FILTER
SYMPTOM:
The toner may spill from the development filter section.
CAUSE:
A gap between the Development Filter Case (A0963141) and the Development Filter (AA012060) allows
toner to escape from the development unit and scatter inside the machine.
SOLUTION:
Production Countermeasure:
A Filter Plate (B0653108) has been added
on top of the Development Filter to ensure
the filter stays properly closed.
Field Countermeasure:
Whenever replacing the Development Filter,
always make sure that the filter lies at or
below the level of the surrounding casing.
Add the new Filter Plate [A] on top of the
Development Filter [B].
Installation Procedure:
1. Place the new Filter Plate [A] on top of
the Development Filter [B] (in the
Development Filter Case[C]).
2. Set the entire Development Filter Case
Assembly [C] in the Development Unit
[D]. The Development Guide Rail
(B0653095) will then hold the new Filter
Plate in place.
3. Attach the Toner Supply Unit [E], which will further secure the new Filter Plate in place.
