Replacing a Charge 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.
