Image on Drum (Panic Stop)
Procedure
This procedure allows the isolation of copy
quality problems by observing the image on
the drum before the transfer of the toner to
the media. If the defect is visible on the
drum before the transfer, the defect is
related to the charge, the imaging, or the
developer.
If
the defect
is
visible on the copy
after the transfer, the defect i s related to the
transfer or fuser.
Make a copy of Test Pattern,
82E5980;
open the right door interlock when the
test pattern i s almost half way into the
document handler.
Remove the Developer Module.
If
the defect is visible on the developed
image, the defect cause
is
related to the
charge, the imaging, or the developer. If
the defect is not visible, the defect cause
i s related to the transfer or the fuser.
