Clearing Paper Jams Note Open and close all printer covers to clear the paper jam message. After removing a sheet of paper, you may need to check other areas to make sure that all paper has been removed. All portions of a jammed piece of paper must be removed or you may run into repeated jams. If the jam persists, try the following: G If you have PostScript installed, use the JAM RECOVERY=ON menu item under the PostScript Menu. The printer will attempt to automatically recover from paper jams. G Execute a formfeed from the computer or the printer's control panel. A formfeed may flush any paper or envelopes left in the printer.
G Check to make sure you have located and removed all scraps of paper from inside the printer. G Use the Event Log Page and Event Log Codes to aid you in isolating where the errors are occurring. Clearing Repeated Paper Jams 1 Check to see that media is correctly loaded in trays and that all width guides are correctly set (not skewed). 2 Try turning over the stack of paper in the tray. If you are using letterhead paper, try printing from Tray 1. 3 Do not use previously printed paper or torn, worn, or irregular paper. 4 Check the media specifications. If it is outside of the recommended specifications, problems may occur.
(See the HP LaserJet Printer Family Paper Specifications Guide.) 5 The printer may be dirty. Clean the printer as described in the first section of this chapter. 6 Check that paper loaded in Tray 1 is NOT longer than 17.7 inches (450 mm) or wider than 11.7 inches (297 mm). (These are the maximum dimensions that the printer can feed; otherwise the printer will jam.) 7 Make sure that Tray 4 and Tray 5 are set for the size of paper installed and that the tray is not overloaded with paper. 400 Chapter 7 Troubleshooting C4085-91087
