RTB Reissue
The items in
bold italics
were corrected or added.
Expiration
This is to announce the expiration of the information originally announced in this
bulletin. Considering the time elapsed since December 2011 when the drum charge
unit was modified, it is expected that the drum charge units of the previous type
(D0742195) are no longer used in the field.
This RTB provides additional information for RTB# RD074041 (troubleshooting instructions
for “banding at small intervals”).
Additional info
When replacing the drum charge unit (D0742195) at its PM cycle, check if the new drum
charge unit to be replaced with is installed with the gear, and if installed, it is
recommended to remove the gear.
Work time to remove the gear is approximately 2 minutes.
Background
The drum charge unit was modified in December 2011 by simply eliminating the gear in
order to reduce the chances of small interval (2-3mm) bandings.
While the modification has been applied to the mass production since December 2011,
unmodified units (D0742195) will still remain as service parts in the field for a while.
