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 3100 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” in this chapter. Then, curl
or roll the item in the direction of the
printed side, unroll it, and reload the item.
