Banding across the print with differences in color and gloss
Description of the problem
Your print contains a banding across the media with a difference in color and gloss. The
intensity of the banding can vary from left to right or vice versa. A clear picture of banding
is visible on the side edge of your print. Banding mostly occurs in the Production mode
at 
densely printed areas.
You 
can perform an additional check to identify the problem. Simply measure the width
of the banding. Each print mode has a typical banding width. The following table describes
the connection between the print modes and the banding widths.

Cause 
of the problem • There are time differences at the turning point of the carriage unit.
At
 one side, the time between 2 swaths is short (short turn). At the other side, the
crystallization
 time between 2 swaths is long (long turn). Differences in the crystalliza-
tion 
time of the toner can cause the banding patterns.
• The 
paper steps are not optimal.

							Horizontal, wavy lines across your print
Description of the problem Your print contains horizontal, wavy lines across the media.
These 
light or dark lines
• appear
 in all colors
• can 
vary in thickness from left to right or vice versa
• can
 
become lighter or darker across the media.
You 
can perform an additional check to identify the problem if you measure the distance
between the wavy lines. Each print mode has a typical distance between the wavy lines.
The

 
following table describes the relation between the print modes and the distances.

							Thin horizontal, coloued or white lines across your print
Description of the problem
Your print has one of the following problems.• Thin horizontal,
 colored lines in the multiple color areas
• Thin horizontal,

 white lines in the CMYK mono color areas.
The 
thin lines are also visible as colored lines in RGB areas and gray areas.
Cause 
of the problem During a swath of the 'Imaging devices', a nozzle drops out or a poor functioning nozzle
misdirects the droplets. It is possible that the system compensates for the nozzle dropout
during the next swath.

How to solve the problem 1.Check if the system compensates for the nozzle dropout during the next swath.
2. If
 the system does not compensate for the nozzle dropout, you must print the Customer
Acceptance 
Test.
3. Check the colored bars of the test print.
Note:
Either check the test print on the second half of the print or reprint the Customer Accep-
tance Test and check the second print. When the colored bars are OK, the system functions
correctly. However, it is always advised to switch 
to a higher print mode. 4.
Select a higher print mode, even when 
you use the 'Océ Print Assistant'.
5. Try to
 
print on another media.
6. If the colored bars of the Customer Acceptance Test demo print still show lines you must
contact 
the Océ Helpdesk.
