Faxes are
transmitting or
being received
very slowly. You may be sending or receiving a very
complex fax, such as one with many
graphics.
The receiving fax machine may have a
slow modem speed.
The resolution at which the fax was sent
or is being received is very high. A higher
resolution results in better quality, but also
requires a longer transmission time.
If there is a poor phone line connection,
the HP LaserJet 3100 product and the
receiving fax machine slows down the
transmission to adjust for errors.
If you are sending an electronic fax, there
may be too many programs open besides
the PC fax program.
If you are using the PC fax program, 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.
Complex faxes take longer to be sent or
received.
The HP LaserJet 3100 product only sends
the fax at the fastest modem speed the
receiving fax machine can accept.
If you are receiving the fax, call the sender
and ask them to lower the resolution and
resend the fax.
If you are sending, lower the resolution
and resend the fax. See “Adjusting the
resolution” in chapter 3 to change the
current resolution setting or “Changing the
default resolution” in chapter 8 to check
the default setting. The current resolution
setting overrides the default.
Hang up and resend the fax.
Other applications may be using needed
memory. Try closing all other open
applications and resending 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.
