Envelope problems CAUTION High rates of jams, gray areas printing on envelopes, or wrinkling can indicate problems with envelopes. Frequent envelope jams Overfilling the envelope tray and misadjusting its guides are the most common causes of jams. However, if the envelope tray is properly loaded, the envelopes might be causing the problems. To recover from an envelope jam, follow the directions that are listed in your HP LaserJet printer user guide. Do not reuse jammed envelopes. Doing so can damage the printer. Cause Envelopes are poorly manufactured. Envelopes are not creased sufficiently to have sharp edges. Envelopes are wrinkled, bent, or curled. Envelopes are too stiff or heavy. Stiff or heavy envelopes cannot negotiate the paper path or be picked up from the envelope tray. Envelopes are too smooth (do not have enough friction for transport) or too rough Envelope is inserted too far into the manual feed slot. Action(s) q Make sure that the leading edge is straight, and has a sharp, well-creased fold. The envelope must not have more than two thicknesses of paper along any leading edge. The folded layers of paper should come to a point at the leading-edge corners. (See the figure in "Envelope construction" on page 11.) q Purchase envelopes that are manufactured correctly, or run the side of a pen or pencil over the envelope edges to flatten them. q Crease the leading edge of the envelope with the side of a pen or pencil, or change to a different type or brand. q Make sure that the envelope's leading edge, which enters the printer first, is straight, and that it has a sharp, well-creased fold that has no more than two thicknesses of paper. q Use a lighter-weight envelope. Do not exceed the 2 basis weight of 105 g/m (28 lb). q Use the printer's most direct (straight-through) paper path. q Change to a different type of envelope. q Insert the envelope only until you feel a slight resistance. 26 Envelope problems ENWW

Envelope problems
High rates of jams, gray areas printing on envelopes, or wrinkling can indicate problems
with envelopes.
Frequent envelope jams
Overfilling the envelope tray and misadjusting its guides are the most common causes of
jams. However, if the envelope tray is properly loaded, the envelopes might be causing the
problems.
To recover from an envelope jam, follow the directions that are listed in your HP LaserJet
printer user guide.
CAUTION
Do not reuse jammed envelopes. Doing so can damage the printer.
Cause
Action(s)
Envelopes are poorly manufactured.
●
Make sure that the leading edge is straight, and
has a sharp, well-creased fold. The envelope must
not have more than two thicknesses of paper
along any leading edge. The folded layers of
paper should come to a point at the leading-edge
corners. (See the figure in
“Envelope
construction” on page 11
.)
●
Purchase envelopes that are manufactured
correctly, or run the side of a pen or pencil over the
envelope edges to flatten them.
Envelopes are not creased sufficiently to
have sharp edges.
●
Crease the leading edge of the envelope with the
side of a pen or pencil, or change to a different
type or brand.
Envelopes are wrinkled, bent, or curled.
●
Make sure that the envelope’s leading edge, which
enters the printer first, is straight, and that it has a
sharp, well-creased fold that has no more than two
thicknesses of paper.
Envelopes are too stiff or heavy. Stiff or
heavy envelopes cannot negotiate the
paper path or be picked up from the
envelope tray.
●
Use a lighter-weight envelope. Do not exceed the
basis weight of 105 g/m
2
(28 lb).
●
Use the printer’s most direct (straight-through)
paper path.
Envelopes are too smooth (do not have
enough friction for transport) or too rough
●
Change to a different type of envelope.
Envelope is inserted too far into the
manual feed slot.
●
Insert the envelope only until you feel a slight
resistance.
