ENWW Chapter 7 Troubleshooting 207
Tray 2 or tray 3 input area
Note
If paper has entered the print-cartridge area, follow the instructions in
“Print-cartridge area” on page 208. It is easier to remove paper from the
print-cartridge area than from the paper-feed area.
1 Slide out tray 2 or tray 3 to expose the jam.
2 Remove any misfed paper by pulling it out by the visible edge. Make
sure that all of the paper is aligned in the tray. If tray 3 is installed,
remove any misfed paper and make sure that all of the paper is
aligned in that tray.
3 If the paper is jammed in the paper-feed area and cannot be
accessed from the print-cartridge area, grasp the paper and
carefully pull it free from the printer.
4 For tray 2, push the paper down to lock the metal paper-lift plate into
place. For both trays, slide the tray back into the printer.
5 To reset the printer and continue printing, open the top cover all the
way and then close it.
Note
If the Attention light does not go out, jammed media remains inside the
printer. Check the paper-feed and rear-output areas for jams. For
printers that include a built-in duplexer (HP LaserJet 2300d printer,
HP LaserJet 2300dn printer, and HP LaserJet 2300dtn printer), check
the duplexer area.
