Symptom
Toner leaks from the aperture of a used waste toner bottle when the bottle is full and
pulled out from the mainframe.
Cause
There are two possible causes for this symptom.
1. The entrance seal [A] attached to the old bottle (D0746670 or older) is slightly
oversized and does not completely seal the aperture.
2. The entrance seal [A] was damaged when pulling out the waste toner bottle.
Note
The old toner bottle (D0746670 or older) was modified, and the new toner bottle
(D0746590 or newer) has a narrower entrance seal.
Action
Always replace with a new entrance seal [A] (D0746684) when reusing the waste toner
bottle regardless of the bottle type, before or after the modification, to prevent toner
leakage caused by a worn entrance seal.
