The printer
feeds multiple
sheets or jams
frequently
from the input
tray.
Paper guides are not adjusted properly. Slide the guides against the sides of the
stack in the input tray to center the
paper. Make sure the guides are not
adjusted too tightly or to loosely against
the media stack.
Paper was not removed from the input
tray before refilling the tray.
Always remove paper from the input tray
before refilling it.
The input tray is overfilled. Remove some of the sheets. The input
tray can hold up to 250 sheets of 20-lb
(75-g/m
2
) bond weight paper (less for
heavier paper) or from 20 to 30
envelopes.
The paper was poorly cut by the
manufacturer and is sticking together.
“Break” the ream of paper by curving it
into an upside-down u-shape; this can
effectively decrease multifeeds. Also try
turning the paper around to feed the
opposite end first, or use a different type
of paper.
The paper does not meet HP’s
specifications for print media.
Make sure that the media meets
specifications detailed in the Print Media
Guide for the HP LaserJet printer family.
The output capacity was exceeded in the

for heavier paper) to fill the paper output
bin.
