BULLETIN NUMBER:
APPLICABLE MODEL:
GESTETNER – DSC38F
RICOH – AP3850C
SAVIN – SLP38CDE
SUBJECT: WHITE LINES IN BLACK HALFTONE AREAS
SYMPTOM:
The following types of white lines may appear in black halftone areas at machine installation:
•
Horizontal and Straight (broken or continuous)
•
Short, Vertical or Wavy
CAUSE:
Vibrations during transportation may cause scratches on the black OPC drum, as the image transfer belt is
always contacting the black PCU during this time.
NOTE: The lines are not visible with the G060, as a different printer gamma is used -- the gamma used on
the G082 is designed to show more detail in halftone areas.
PERMANENT SOLUTION:
A modification will be applied whereby the black PCU and transport unit are separated before shipping. This
modification is required to allow the units to be separated and still be able to close the front cover
TEMPORARY SOLUTION:
Until the permanent solution can be applied, G082 machines are shipped with the transport unit separated
from the black PCU. Specifically, the transport unit lever has been removed before shipping to allow the front
cover to be closed.
