Print Paper Checks
•
Be sure the recommended paper for this printer is being used.
•
Check the paper for dampness. Make a trial print with paper from
a newly opened package, and check the result.
EP Cartridges
If blank spots appear on an output image, there is a chance that the
toner is not even. Rock the toner cartridge and make a print to see if it
has evened out.
Other
If a packaged EP cartridge is opened soon after being moved from a
cold room to a warm room, condensation will appear inside the
cartridge; this can cause various image defects. In such cases, be sure
to instruct the customer that it is necessary to leave the cartridge sealed
for one to two hours at room temperature to allow it to acclimatize.
Troubleshooting
Use the error message tables, symptom table, and service checks, in
this chapter and the diagnostic aids in Chapter 3 to diagnose a failure.
If the operator panel is blank, black, has diamonds across the display, or
appears unusual, unplug the controller card and run the engine print
test using the base machine test print. Go to "Diagnostic Aids" on
page 6-16 to diagnose this problem because the operator panel or
controller card may have a defect.
If your machine makes it through POST without an error but you have a
symptom, go to the appropriate symptom table, locate your symptom
and take the appropriate action.
If an error is displayed, locate it in the following "Error Message Tables"
and take the appropriate action.
If an error message appears while you are working on the printer, go to
the error message table and take the indicated action.
