HP LaserJet 3100 All-in-One Printer series - Manual (Page 203)

202 9 Troubleshooting and Maintenance EN
There are dark
streaks or lines on
sent faxes or the
image quality is
poor. The scanner glass may be dirty. Make a copy of the item you are faxing. If
the same problem appears, the scanner
glass may be dirty. See “Cleaning the
scanner path” in this chapter for cleaning
instructions.
If the copy is ok, try adjusting the
resolution and contrast on the fax and
resending. If the quality is still not good,
there may be a problem with the receiving
fax machine, such as it cannot receive
faxes at a high resolution.
The volume for
sounds coming
from the HP
LaserJet 3100
product is too high
or too low. The volume setting needs to be adjusted. See “Controlling sound volume” in chapter
8 for instructions on changing volume
settings.
Long pages aren’t
feeding. The page may be longer than 39 inches
(991 mm). 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, rescan the page. When the scanner
reaches the 39 in (991 mm) mark, the
control panel displays
Long Page? START
to Continue for a few moments only.
Quickly press S TART to continue scanning.
If you do not, the message disappears
and the scanner stops scanning because
it thinks the page has jammed.
If you are sending a fax longer than 39 in
(991 mm), you can also use the “Sending
long pages” procedure (chapter 3). That
procedure ensures that long pages go
without having to monitor the task and
press Start before the scanner shuts off.
You receive this
software
message:
“JetSuite Fax has
detected that the
HP LaserJet 3100
is switched off or is
not connected to
the computer.” Either the power cord for the HP LaserJet
3100 product or the parallel cable
between it and the computer is not
securely connected. Check that the power cord is securely
connected between the HP LaserJet 3100
product and the power source. Then,
check that the parallel cable is securely
connected. After you have checked both,
click Retry. If you click Cancel, you will
not be able to receive faxes to or send
faxes from the computer until you start (or
restart) the JetSuite software or restart the
computer.
