Service action

Ask the customer to send a sample printout via fax or e‑mail.
Identify the cause of the issue using the

from the
Help Menu
. To do this, navigate to:
Menus button
>
Help
>
Print Defects Guide
.
Measure the defect's interval. Refer to the sample printouts in the customer-level section of this document to see how the measurement was done.
The
Charge Roll
repeating defect distance is
30mm
(
1.18 inch
).
Check the
Supply Level
of the
Photoconductor Unit
by printing
Device Statistics
. To do this, navigate to:
Menu button
>
Reports
>
Device Statistics
.
If the
Supply level
is
low
, tell the customer to purchase a replacement
Photoconductor Unit
as it may already be worn out.
If the Supply level is still sufficient, proceed with the next step.
Check whether the customer has a different
Photoconductor Unit
in order to try swapping it with the original as a test, since if the defect clears when using a different
Photoconductor Unit
that would prove the original is defective. Should the customer
not
have a replacement unit to try this test with, however, send a replacement
Photoconductor Unit
as the original one might be defective.
If the defect persists even after replacing the
Photoconductor Unit
, escalate the call to your next level of support.
