Output quality problems
[59]
■
Thin (White) Stripes or weak lines
(Nozzle dropouts)
■
Stripes per primary colour
■
Stripes in parts / dotted lines but
also over the entire width
Usually you will find these stripes only
in the check mode. In this mode some of
these lines are acceptable, because
there is no nozzle compensation.
The nozzle compensation, that is used in
the release mode and in the presentation
mode, will correct the lines.
■
If these lines are unacceptable,
switch to a slower mode ('Release' or
'Presentation'). Perform an 'Optimise
print quality' test. The test checks all
printheads and the printer
compensates for missing nozzles.
■
Check if the maintenance cassette is
clean. If necessary, clean the wipers
with a moist, lintfree cloth.
[60]
Banding in all colours with
alternating light and dark bands
(bands can have different widths)
Perform an 'Optimise print quality' test.
If the problems persists, repeat the
'Optimise print quality' test.
Note:
It is advised to use the
'Release' or 'Presentation'
mode to prevent banding.
