Replacing a Corotron
When to replace a charge corotron
Unlike other consumable products for the digital
press, a “replace corotron” message does not
display on the UI. You should replace a corotron
unit only when an image quality problem called
banding, or rainbow banding, appear on
prints. The Maintenance tab screen displays a
yellow triangle or a red circle when a pre-
determined number of prints using a corotron unit
have been made. You should ignore these symbols
and continue to use the corotron until banding is
seen on prints.
Which charge corotron to replace
If you notice streaks or bands of color across prints,
a charge corotron unit may need to be replaced. To
determine which unit needs replacing, retrieve and
print the file named
Corotron Test.pdf
from the
Customer Documentation CD. The output print will
show banding in the color bar of the corotron that
needs to be replaced. Banding of multiple color
bars means several corotrons need to be replaced.
