Table 8 (Page 6 of 7). Troubleshooting Problems:Symptoms and Actions

Symptom Action
Blank pages If all sheets are blank, the toner supply could be low but the toner sensor
is not detecting this condition.
Response: Replace the toner cartridge. See “Changing the Toner
Cartridge” on page 140 for instructions on removing and replacing the
toner cartridge.
Random blank pages during a print job can be caused by multiple sheets
of paper being fed through the machine simultaneously.
Response: Reload the paper tray with fresh, dry paper. Fan the paper
before loading it. If the problem still exists with the new toner cartridge
installed, check the page count. See “Machine Information Menu” on
page 80. If you have printed over 350,000 pages, 700,000 pages, and so
on, you may want to consider installing a usage kit. See Appendix D,
“Installing the Usage Kit” on page 241. for more information.
