Troubleshooting
■ No automatic switching between telephone and fax calls.
The machine may not be set to switch automatically between telephone and fax
calls.
•For the machine to switch automatically, the receive mode must be set to Fax/Tel
Mode, ANS.MACHINE MODE, or DRPD (1 Chapter 8). If you have set
ANS.MACHINE MODE, confirm that an answering machine is connected to the
machine and that it is turned on with an outgoing message properly recorded
(1 p. 8-9).
The machine may have a document stored in memory, leaving little or no memory
available.
•Print, send, or delete any documents you no longer need to be stored in memory
(1 p. 9-4).
An error may have occurred during reception.
• Check the LCD for an error message (1 p. 13-8).
•Print an ACTIVITY REPORT (1 p. 11-3) and check for an error code (1 p. 13-8).
The multi-purpose tray may be empty.
• Make sure paper is loaded in the multi-purpose tray (1 p. 2-16).
The other party’s fax machine may not send the CNG signal that tells your
machine that the incoming call is a fax call.
• Some fax machines cannot send this signal. In such cases, you will have to receive
the fax manually (1 p. 8-6).
■ Cannot receive a document manually.
You may have disconnected the call by pressing Start/Copy or dialing the remote
receiving ID after hanging up.
• Always press Start/Copy or dial the remote receiving ID before hanging up.
Otherwise you will disconnect the call (1 p. 8-6).
■ Print quality is poor.
You may not be using the correct paper type.
• Make sure you load paper that meets the requirements for the machine (1 p. 5-2).
The other party’s fax machine may not be functioning properly.
• The sending fax machine usually determines the machine’s quality. Contact the other
party and have them check that the scanning components of their fax machine are
clean.
Error Correction Mode (ECM) may be disabled.
• Make sure ECM is on (1 ECM RX, p. 14-7).
■ Faxes do not print.
The cartridge may not be installed properly.
• Make sure the cartridge is installed properly (1 p. 2-13).
The cartridge may need to be replaced.
• Replace the cartridge (1 p. 12-6).
