Waves / Cockle problems #
Description
Graphical representation of the prob-
lem
Waves and or light stripes in the paper
feed direction
Bands can consist of waves and / or slight
color differences of approximately 1cm.
Check

 if 
the correct media is defined on
the
 system.
If

 yes, select 
a different media type.
When
 the printer applies a lot of ink the
paper

 can cockle. Use premium papers or
coated papers because they 
have a better
resistance
 towards 
waving (also called
cockle).
 If the problem persists, the use
of

 heavier media will 
reduce cockle.
The
 
following papers will never show
cockle. ■ 'High
