Part information about drum drive gear
From:
1st Tech Service Sect., PP Tech Service Dept.
Classification:
This RTB is to inform the new part information about the drum drive gear, which is
the countermeasure for the 8mm pitch banding.
In the past, the only way to fix the 8mm pitch banding was to replace the "Drive
Unit: Around The Photoconductor:Ass'y". Only the gear in the drive unit needs to
be replaced.
Symptom
Banding of about 8mm pitch appears throughout the page
