APPLICABLE MODEL: AFICIO Color 5106/5206
SUBJECT: MAGENTA BANDING
SYMPTOM:

Insufficient conductivity of development bias between the Development Sleeve and its shaft.

in toward the development sleeve. A lock washer has been added to insure the ball bearing does not fall off
during maintenance.
Note:
The new Development Sleeve is used for the Magenta Development unit only.The Development
Sleeve number for the Yellow Development Unit remains the same.The recommended bearing
contains conductive grease to ensure proper electrical conductivity. Do not substitute any other
parts for those listed below.
