Print-Quality Troubleshooting

5-15

Solid Dark or Dirty Prints, No Border

The prints appear very dirty and brown over
the entire page.

This print-quality symptom is a composite
image of all colors with no margin. This is
caused by a charge voltage failure. For
information on the Imaging Unit charge
contacts, see "Theory of Operation" on
page 2-1.

Note

After replacing any component in Step 2 or 3, run the Clean the Imaging Unit
from the Maintenance section of Service Diagnostics. See "Service Diagnostic
Tests" on page 3-9.

Troubleshooting Procedure

Step

Check

Yes

No

1

Is the problem resolved after

replacing the Imaging Unit?

Complete

Go to Step [2].

2

Inspect the Imaging Unit charge

voltage contacts (PL9.1.5) and the

Bias Housing Assembly (PL 9.1.4) in

the printer for any damage or

defects. See "Imaging Unit Charge

Voltage Contacts" on page 2-36.

Complete

Go to Step [3].

3

Is the problem resolved after

replacing the Sub-High Voltage

Supply Board, page 8-87?

Complete

Replace the Engine

Control Board,

page 8-107.
