							Output quality problems
Introduction
The Océ ColorWave 300 offers three possibilities to check the quality of your printed
output. ■ Make a quality check print
■ Make

 a tone scale area print
■ Make

 a demo print.
This

 section describes the problems you can analyze by making one of these check prints.
The 
Optimize print quality  section describes how you can solve problems with the
quality ‘Optimize the output quality on the printer ’
 on page 263.
Overview of output quality problems - Graininess Graininess problems #
Description
Graphical representation of the prob-
lem
Color specific graininess
Perform an 'Optimize print quality' test.
The 
test checks all printheads and the
printer
 compensates for missing nozzles.
Note:
After the 'Optimize print quality'
test is completed, the printer may
ask you to replace a printhead. In
this case, 
take out the printhead
and
 clean the contact area with a
lintfree 
cloth.
If the printhead is still not accept-
ed, insert a new printhead. Chapter 6

							Overview of output quality problems - Stripes and Banding
Stripes and Banding problems #
Description
Graphical representation of the prob-
lem
Small stripes over the entire width of
the print (color independent)
Perform an 'Optimize print quality' test.Note:
This problem can occur in all
print modes. ■
Thin (White) Stripes or weak lines
(Nozzle dropouts)
■ Stripes per primary color
■ 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 'Presen-
tation'). Perform an 'Optimize print
quality'

 test. The test checks all print-
heads and the printer compensates for
missing nozzles.
■ Check

 if 
the maintenance cassette is
clean.
 
If necessary, clean the wipers
with
 
a moist, lintfree cloth. Chapter 6

Note:
After the 'Optimize print quality'

ask you to replace a printhead. In
this case,
