Jam troubleshooting

Media jams occur when media either does not reach or does not clear the document-detect sensor (PS1) and leading-edge sensor (PS2) in a specific amount of time (see “ADF document- feed system” on page 67 and “ADF components” on page 56). If a paper jam occurs, a 13.XX PAPER JAM message appears on the MFP control panel.

Jams

Jams occur most often when the following conditions exist:

●Media trays are not correctly loaded or the sliding media guides are not correctly positioned.

●The print media does not meet the specifications listed in the Print Media Guide for the HP LaserJet printer family.

●The media is in poor condition. See “General guidelines for using the ADF unit” on page 28.

●The MFP needs cleaning. See “Cleaning the product” on page 36.
