See "Cannot receive a fax" on page 72, in the Troubleshooting
faxing section.
In FAX/TEL or ANS MODE, the F50 MFP will switch to receive mode
when it detects CNG tones. If transmission did not include CNG
tone, you will have to receive the fax manually. Press the Hook
button or lift the handset of the phone connected to the F50 MFP
and press Start Start Start Start.
In FAXONLY or FAX/TEL receive modes, confirm the F50 MFP ring
count is set to 2 rings or less. In ANS. MODE, confirm that the
answering machine is set to 2 rings or less, with an outgoing
message recorded at 12 seconds or less.
See "Setting up the Fax Receive Mode" on page 14.
Wait for the F50 MFP to finish, then try again, and/or delete
unnecessary documents from the memory.
Confirm that your phone line is correctly connected to the L jack
on the F50 MFP. If you are using a phone or answering machine,
connect it to the jack marked by a telephone icon.
Check the F50 MFP by making a copy. If the copy is clear, the
problem may originate from sender's fax machine. If the copy is
spotted or dirty, clean the scanner components.
You may have disconnected the call by pressing Start and
hanging up before the sender could send the fax.
The sending fax machine usually determines the fax's quality.
Call the sender to resolve the problem.
See the solutions in the "Troubleshooting Printing" section on
page 74.
For the F50 MFP to switch automatically, the receive mode must
be set to FAX/TEL AUTO SW, ANS. MACHINE MODE, or DRPD. If you
have set ANS. MACHINE MODE, confirm that an answering
machine is connected to the F50 MFP and that it is turned on with
an outgoing message properly recorded. See "Setting Fax Receive
Mode" on page 14.
Check the LCD for an error message, or print an ACTIVITY REPORT
to check for an error. See "Setting up and Printing Reports" on
page 16.
