Subject: Change of Part and Developer Agent Automatic Discharge Structure
Model: FC22
Category Field Application UNIT
Change of Parts To be applied when necessary Developer
FactoryApplication: From Mar. 2000
CONTENT
In the case of automatic discharge of the developer material, sometimes the discharge shutter
cannot be opened or closed.
C33 error (abnormality in the operation of the developer material discharge shutter)
The alignment of the gears driving the developer material discharge shutter is shallow and
occasionally the gears will jump. This countermeasure is to make the alignment normal.
This change corresponds to machines assembled from Number BA010311; those before are
not included. For machines which have not had this countermeasure applied, when a C33
error happen, using [the assembly instructions] below, carry out adjustment. However, if the
part change below is made, this adjustment is unnecessary.
[Assembly instruction]
