Correcting Print Image Errors
General Information
There can be many causes behind print image errors. If the print image errors cannot be
corrected by the options described, then let Service know.
Note:
If print image errors appear on the front page, then the cause lies in the upper print unit;
if the print image errors appear on the back page, then the cause lies in the lower print
unit. The setting in the 'Print image' -> 'Job control' menu must be observed for this:
■
'Face up'
Front page = top side
■
'Face down'
Front page = bottom side
Note:
If the print image errors only occur in one color, then the cause lies with the relevant
color station in the upper and/or lower print unit.
Note:
The photoconductor belt together with the photoconductor blade and the transfer belt
must only be replaced when print image errors occur that are clearly caused by these
expendables. The photoconductor belt and the transfer belt can only be the cause for
print image errors if the print image errors regularly occur after a belt rotation, i.e. after
approx. 1.78 m (69.9 inch).
Note:
Preinstalled test print jobs can be started via the 'Configuration' -> 'Emulations' -> 'Test
print' menu. These print jobs, which are grouped in test sequences, can be used to opti-
mize the print quality for a certain application. These optimized settings can then be
saved in a setup.
