Printer selects media from the wrong tray.

Cause Solution

The tray selection in the software program might be incorrect.

The configured size does not match the size of the media that is loaded in the tray.

For many software programs, the paper tray selection is found on the Page Setup menu within the program.

Remove any media in other trays to make the printer select from the correct tray.

For Macintosh computers, use the HP LaserJet Utility to change the priority of the tray.

Through the control panel, change the configured size to match the size of the media that is loaded in the tray.

Printer does not pull paper from tray.

Cause

The tray is empty.

The paper guides are set incorrectly.

Paper curls when it exits the printer.

Solution

Load paper in the tray.

To set the guides correctly, see Loading trays.

For the 500-sheet paper tray, make sure that the leading edge of the paper stack is even. An uneven edge can prevent the lift plate from rising.

Cause Solution

The paper curls when it exits to the top output bin. Open the rear output bin to allow the paper to exit in a straight path through the printer.

Turn over the paper that you are printing on.

Reduce the fusing temperature to reduce the curling. (See Selecting the correct fuser mode.)

First sheet of media jams in the print-cartridge area.

Cause Solution

A combination of high humidity and high temperature is affecting the media.

Adjust the printer for high humidity and high temperature conditions.
