❏ Check if the printer is out of paper. If the printer is out of paper and its memory is full, it will not be
able to receive faxes. Refill paper in the MP tray or the paper cassette. The printer will print all of
the faxes it has saved in memory and will then resume answering fax calls.
Faxes are transmitting or being received very slowly
Try one or more of the following solutions.
❏ Check if you are sending or receiving a very complex fax. A complex fax, such as one with many
graphics, takes longer to be sent or received.
❏ Check if the receiving fax machine has a slow modem speed. The printer only sends the fax at the
fastest modem speed the receiving fax machine can use.
❏ Check if the resolution at which the fax was sent or received is very high. A higher resolution
typically results in better quality, but also requires a longer transmission time. If you are receiving
the fax, call and ask the sender to lower the resolution and resend the fax. If you are sending, lower
the resolution and resend the fax.
❏ Check if there is a poor phone line connection. If there is a poor phone line connection, the printer
and the receiving fax machine slow down line transmission to adjust for errors. Hang up and
resend the fax. If this does not work, have the phone company check the phone line.
Quality problems occur
Check if Image Quality Selection and Fax Density Selection under the Basic Setting
tab are specified correctly.
Smudges appear in printouts
Clean the document table. For details, see “Cleaning the document table and the exposure window for
Auto Document Feeder” on page 203.
The image of the received data is divided or reduced
Check if the size of the paper being output matches the size of the received data.
Sender information is not printed
Try one or more of the following solutions.
❏ Check if Print Sender Info is set to On. For details, see “Transmission Settings” on page
