This problem may occur at the point where pages stop in the fuser. The

adjusting the printer.
Any other print quality problem or

corrective steps.
Call your service representative. See “Service Call Procedure” on page 13.
Sudden Failures
If your printer has been operating satisfactorily for a reasonable period and then
suddenly fails, consider the following questions:
v Is the printer processing a new application?
v Is the printer using new forms?
v Are forms or other supplies being obtained from a new supplier?
v Have the IBM Advanced Function Printing licensed programs been updated?
v Have any changes occurred in the operating system environment?
v Has the printer been recabled or moved?
v Have any configuration items been changed recently?
If the answer to any of these questions is “yes”, you may have found the cause of
the problem. Work with your system programmer, service representative, or
application owner to resolve the situation.
