Scanning is
extremely slow
.
The HP LaserJet 3100 product is
scanning a file with a high resolution.
There are too many programs open while
you are trying to scan.
The parallel cable may be loose, you may
have the parallel cable plugged into the
wrong type of port, or the parallel port
setting is incorrect.
The parallel port mode may not be set
correctly.
If you chose Photo resolution, 8 bit grey
scale or a custom resolution that is very
high, you may have created a very large
file that is slow to scan.To speed up the
scanning process, try choosing a lower
resolution.
Other programs may be using needed
memory. Try closing all other open
applications and rescanning the
document.
Check that you have the parallel cable
plugged in securely on the back of the HP
LaserJet 3100 product. Check that the
cable is plugged into the parallel port, not
the serial port. PC faxing may also be
slow if you have an SPP-compliant
parallel port. An ECP-compliant parallel
port is strongly recommended. Check the
parallel port setting. For more information
on your parallel port, please see appendix
C and your computer’s documentation.
If the parallel port mode is not set
correctly, you may need to change the
settings to allow the computer and HP
LaserJet 3100 product to communicate.
See Appendix C.
The Document
Assistant blinks on
and off on the
computer screen
even when no
document is
loaded in the
document feeder
tray. The HP LaserJet 3100 product is
connected to a parallel port being shared
with another device. The HP LaserJet 3100 product cannot be
connected to the same parallel port on the
computer as another device. You must
buy an additional parallel port or
disconnect one of the two.
Scanned items
are not appearing
on the computer. The item may not have been saved as a
file. Make sure you save scanned items as
files. See “Saving scanned items” in
Chapter 6.
