64 Troubleshooting
Always press [Start/Copy] or dial the remote receiving ID before hanging up the
Handset, otherwise you will disconnect the call (see page 35).
Make sure you dialed the correct remote receiving ID (see page 35).
Make sure you load paper that meets the paper requirements for the fax (see
page 21).
Clean the FINE cartridge print head if necessary (see page 54).
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 46).
Make sure the FINE Cartridge is installed properly (see your setup sheet or
page 50).
Be sure to remove the protective tape from the FINE Cartridge before you
install it (see your setup sheet or page 50).
Clean the FINE Cartridge print head if necessary (see page 54).
Determine if the problem is with the FINE Cartridge and replace if necessary
(see page 50).
Make sure a document is not set.
Cancel sending, printing, or maintenance as soon as possible.
Error Correction Mode (ECM) sending/receiving should eliminate such
problems. However, if the telephone lines are in poor condition, you may
have to try again.
Lower the reception speed (see <RX START SPEED> on page 47).
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.

received in normal mode without error checking.
