70 Troubleshooting
For the fax to switch automatically, the receive mode must be set to <FAX/TEL
AUTO SW> (Fax/Tel mode) or <ANS.MACHINE MODE*> (see page 28), or
TAM MODE* must be set (see page 38). If you have set <ANS.MACHINE
MODE*>, check that an answering machine is connected to the fax and that it is
turned on with an outgoing message properly recorded (see page 30).
Print out any documents stored in memory (see page 36).
Check the LCD for an error message (see page 75).
Print an activity report and check for an error (see page 54).
Make sure paper is loaded in the Multi-Purpose Tray (see the Easy Setup
Instructions).
Some fax machines cannot send the CNG signal that tells your fax the incoming
call is from a fax machine. In such cases, you will have to receive the document
manually (see page 30).
Always press [Start] or dial the remote receiving ID before hanging up the
Handset, otherwise you will disconnect the call (see page 30).
Make sure you dialed the correct remote receiving ID (see page 30).
Make sure you load paper that meets the paper requirements for the fax (see
page 16).
Clean the FINE cartridge print head if necessary (see page 60).
The sending fax machine usually determines the quality of the document. Call
the sender and have them make sure their fax machine is functioning properly.
Make sure ECM is on (see ECM RX on page 51).
Make sure the FINE Cartridge is installed properly (see the Easy Setup
Instructions).
Be sure to remove the protective tape from the FINE Cartridge before you
install it (see the Easy Setup Instructions).
Clean the FINE Cartridge print head if necessary (see page 60).
Determine if the problem is with the FINE Cartridge and replace if necessary
(see page 56).
Make sure a document is not set.
