busy. This happens especially if the
printer is sharing the line with other
devices (telephone, answering
machine).
• Set the printer to redial.
•
Increase the time between the
redial attempts.
• Place a test call to the number to
which you want to send a fax to
make sure that it is working
correctly.
• If the telephone line is being used
by another device, then wait until
the other device is finished before
sending the fax.
• Schedule to resend the fax at a later
time.
• Set the printer to scan before
dialing. The scanned document is
saved in the printer memory. The
printer can then retrieve it and
automatically redial the number.
