Clearing Paper Jams
If the printer’s control panel displays a paper jam message, look for
paper in the locations indicated in Figure 19, then see the procedure
for clearing the paper jam. You might need to look for paper in other
locations than indicated in the paper jam message. If the location
of the paper jam is not obvious, look first in the top cover area
underneath the toner cartridge.
When clearing paper jams, be very careful not to tear the paper. If
a small piece of paper is left in the printer, it could cause additional
jams. If paper jams are a recurring problem, see page 102.
Note The top cover of the printer must be opened and then closed to clear
a paper jam message.
