SUBJECT: TORN IMAGE TRANSFER BELT & SC481
SYMPTOM:
Service Code 481 (Transfer belt mark detection error) is indicated.
CAUSE:
The image transfer belt in the photoconductor unit tears due to the surface of transfer roller loosening.
Additionally, the edges of the roller's may not be smooth, causing the image transfer belt position to shift
causing the belt timing marks not being detected correctly.
SOLUTION:
Production Countermeasure:
The surface coating for the image transfer roller has been changed to stainless steel. This ensures the
image transfer belt will not become scratched. The surface treatment of the roller edges have been made
more smoother.
NOTE: The part number for the new photoconductor unit is B0529100.
Field Countermeasure:
Refer to "Technical Service Bulletin B051/B052 – 030 Reissue" for the necessary procedure when installing
the new and old photoconductor unit in the field.
UNITS AFFECTED:
All copiers listed below and manufactured after the serial numbers provided will have the new parts installed
during production.
