Performance problems
Problem Cause Solution
Faxes are transmitting or being
received very slowly. The fax might be very complex,
such as one with many graphics. Complex faxes take longer to
be sent or received. Breaking
longer faxes into multiple jobs
and decreasing the resolution
can increase the transmission
speed.
The receiving fax machine
might have a slow modem
speed. The device only sends the fax
at the fastest modem speed
that the receiving fax machine
can accept.
The resolution at which the fax
was sent or is being received
might be very high. If you are receiving the fax, call
and ask the sender to lower the
resolution and resend the fax. If
you are sending the fax, lower
the resolution and resend the
fax. See
Changing the default
light/dark (contrast) setting to
change the default setting.
Your telephone line might not
be working. Hang up and resend the fax.
Have the telephone company
check the telephone line.
You are sending a fax via an
international call. You must allow more time to
transmit fax jobs internationally.
The fax activity logs or fax call
reports are printing at
inappropriate times. The fax activity log or fax call
reports settings are not correct. Print a Configuration page and
check when the reports print.
For instructions about setting
log or report printing times, see
To set the fax activity log to
print automatically
or Setting
print times for the fax call report .
The device sounds are too loud
or too soft. The volume setting might not
be adjusted correctly. See Using the device volume
controls .
