Printer Problems
Preventing paper feed and paper jam problems
To prevent frequent paper feed or paper jam problems, use this
checklist of corrective measures:
❏ Use a high quality paper that is not too thin or too rough.
❏ Fan the stack of paper and tap its edges to align it before
loading.
❏ Be sure that you do not load too much paper into the paper
cassettes.
❏ Be sure to adjust the paper guides so that paper can slide in
and out freely.
❏ Never let more than 500 sheets accumulate in the output tray
(face-down tray) on top of the printer.
