“Solving image quality problems” on page 201 and “Solving paper
feed problems” on page 209.
Problem Cause Solution
No parallel port is
available or the
parallel port is
being shared by
another device. If you are copying from the Document
Assistant or the JetSuite Pro software, the
HP LaserJet 3150 product must be
directly connected to the computer’s
parallel port. It cannot share the parallel
port with another device. If you have a device such as an external
disk drive or switch box connected to the
parallel port and want to continue using it,
you must get two parallel ports on your
computer.
Items loaded in the
document feeder
tray fall forward out
of the tray. The item is on a very lightweight media. Do not try to pull the page out because
you may damage the scanner. To remove
the page, see “Clearing jams from the
scanner area” on page 160. Then, curl or
roll the item in the direction of the printed
side, unroll it, and reload the item.
The HP LaserJet
3150 product isn’t
working. The HP LaserJet 3150 product may not
be receiving power.
The computer’s processor is too busy.
The hard drive on the computer may be
very full or is fragmented.
Check that all cords are plugged in at the
HP LaserJet 3150 product and the
computer and that they are plugged into a
live power outlet or power strip.
Also, try removing the power cord from the
back of the HP LaserJet 3150 product and
then reinserting it. If the
Ready message is
displayed on the control panel, the
HP LaserJet 3150 product is receiving
power.
Try copying from the control panel. Try
running fewer programs at the same time
on the computer. Do not perform I/O or
processor-intensive tasks (such as
sending a fax or playing a video game) on
the computer while printing.
Free disk space or defragment the hard
drive. See the computer documentation
for help.
