When to replace a charge corotron assembly
Unlike other consumable products for the machine, 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” appears on the 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 assembly 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
CorotronTest.pdf from the customer documentation CD/DVD. 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.
Banding samples
The following examples of the test print show banding in the color bar of the corotron
that needs to be replaced and in the three-color bar. The three-color bar (CMY) is there
to help you identify which color is showing banding.
