SYMPTOM
Waste toner may sometimes leak from the maintenance kit PCU (G780-17) due to
vibration during parts transport.
CAUSE
Cleaning was not performed on the maintenance kit PCU following final tests on the
production line (only PCUs fitted in the mainframe were cleaned at this stage).
SOLUTION
! PCU cleaning was added to the production process for the maintenance kit PCU.
Applied from: May 2003 production.
! A cap has been added to the maintenance kit PCU to seal the opening between the
PCU and waste toner bottle during shipping.
Applied from: B3173910025 (G780-17).
Note:
1. This cap is not necessary on mainframe PCUs since the O/B waste toner bottle already
covers this opening (see
Important Note
below).
2. The Installation Procedure in the PCU Maintenance Kit has been modified to include the
Important Note below. If any inquiries are received regarding the above symptom,
please advise customers using this note.
Important note for when installing the PCU:
Please be sure to remove the cap [A] before installing the unit.
