HP LaserJet 3150 All-in-One Printer series - Manual (Page 213)

EN Solving paper feed problems 211
The HP LaserJet
3150 product is
feeding multiple
sheets or jams
frequently from the
paper input bin or
single-sheet input
slot. Guides are not adjusted properly.
The paper input bin is too full.
More than one sheet was placed in the
single-sheet input slot.
The paper was poorly cut by the
manufacturer and is sticking together.
The paper does not meet HP’s
specifications for print media.
The output capacity was exceeded in the
paper output bin or front paper output slot.
The pick rollers are dirty and are not
grabbing the paper.
There may be a sensor that is not
operating properly.
Remove the paper from the paper input
bin or the single-sheet input slot. Tap the
sides of the paper stack together, then
reinsert the stack. Or reinsert the single
sheet into the slot. Slide the guides
against the sides of the stack in the paper
input bin or against the single sheet in the
single-sheet input slot to center the paper.
Make sure the guides are not adjusted too
tightly.
Remove some of the sheets. The paper
input bin can hold up to 100 sheets of 20-
lb (75g/m 2 ) bond weight paper (less for
heavier paper) or up to 7 to 10 envelopes,
depending on envelope construction and
operating environment
Place only one sheet at a time in the
single-sheet input slot. If printing more
than one sheet of the same type of media,
use the paper input bin.
“Break” the ream of paper by curving it
into an upside-down u-shape; this may
effectively decrease multifeeds. You may
also try turning the paper around to feed
the opposite end first, or use a different
type of paper.
Order HP’s paper specification guide. To
order, see “Ordering parts” on page 221.
Do not allow more than 100 sheets of 20-
lb (75 g/m
2 ) bond weight paper (less for
heavier paper) to fill the paper output bin.
Do not allow media to stack up in front of
the front paper output slot.
See “Cleaning the print path” on
page 216.
