Symptom
Toner is scattered around the developing assembly since the buffer shutter moves out of the
position.
[Inspected by Canon Inc. ]
Description
When detaching and attaching the developing assembly, tonner was scattered on and around the
developing assembly. Soiled images occurred in some cases.
Cause
The spring of the shutter arm [A] came off by forcibly installing the developing assembly. This left the
buffer shutter [B] open upon detaching the developing assembly, leading to the toner leakage from the
buffer unit.
