If the banding is not caused by aeroworms, continue with the following procedure:
a.
Horizontal banding
i.
Banding present in all colors:
▲
Check the Substrate-Advance Compensation and calibrate if necessary. (
Printer menu
>
Advance calibration
…)
ii.
Banding in one or more colors of the top row:
a.
Execute a check and clean routine, print the printhead status plot and check the number of
blocked nozzles.
b.
If the number of blocked nozzles is roughly greater than 300 in any printhead, perform a
hard cleaning routine, selecting the colors affected.
c.
After executing the cleaning routines, reprint the printhead status plot, the image quality
troubleshooting plot, and check the current state of the printheads (expect to see less
nozzles clogged) and of the banding. If banding is still visible, increase the number of
passes.
d.
If none of the above work, replace the printhead that caused the banding (the one with
most nozzles clogged).
e.
If the problem persists after replacing the printhead, consider it may be a substrate
compatibility issue.
iii.
Banding in one or more colors of any row:
a.
Execute printhead alignment and recheck uniformity with the Image Quality
Troubleshooting Plot.
b.
Execute check and clean, print the Printhead Status Plot, and check the number of blocked
nozzles. If the number of blocked nozzles is greater than 300 in any printhead, perform a
hard cleaning routine, selecting the colors affected.
c.

Wide bands:
a.
Execute printhead alignment.
b.
Check carriage beam position.
c.
