Problem
description
Cause Solutions
The banding is
affecting all the
colors across the job
and is produced by
thin horizontal lines
(dark or light).
If you are using 4 or 6
passes, the cause could be a
substrate advance problem.
Note: With 8 passes or
more, it is unlikely that a
substrate advance problem
will create banding. See the
graininess section for more
details.
During printing, try to reduce
Horizontal Banding by changing the
Substrate Advance
Compensation parameter with the
arrow keys through the “on-the-fly”
button in the Front Panel. Select the
icon, choose Image Quality
Maintenance, Substrate Advance
Calib and Substrate Advance
Compensation.
• If the print shows dark lines then
increase the substrate advance
compensation.
• If the print shows light lines then
decrease the substrate advance
compensation.
At the end of the job, the value will be
reset to the previous one. If you want to
apply your manual correction to
subsequent jobs, do not forget to store
the value in the RIP media preset.
