Q

Is the document loaded?

A

Remove the document, stack it if necessary, and place it on the platen glass or 
load it in the ADF correctly. For more information, see Chapter 3, "Document 
Handling," in the Basic Guide.

Cannot send using ECM (Error Correction Mode).

Q

Does the receiving fax machine support ECM?

A

If the receiving fax machine does not support ECM, the document is sent in the 
normal mode without error checking.

Errors occur frequently while sending.

Q

Are the telephone lines in proper condition? Or do you have a good connection?

A

Lower the transmission speed. (See <3. TX START SPEED> of "Menu 
Descriptions," on p. 8-6.)

Cannot receive a fax automatically.

Q

Is the machine set to receive automatically?

A

For the machine to receive faxes automatically, the receive mode must be set to 
<FAX ONLY MODE> or <ANS. MACHINE MODE>. (See Chapter 5, "Receiving 
Faxes.") 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.
If you set <3. MAN/AUTO SWITCH> to <ON> in <FAX SETTINGS> of the 
Menu, the machine will receive faxes automatically even when the receive 
mode is set to <MANUAL MODE>. (See <3. MAN/AUTO SWITCH> of "Menu 
Descriptions," on p. 8-6.)

Q

Is the machine's memory full?

A

Wait for the machine to finish any fax or print jobs stored in the memory. Then 
ask the other party to resend the fax.

Q

Did an error occur during reception?

A

Print an ACTIVITY REPORT and check for an error. (See "Printing the 
ACTIVITY REPORT," on p. 6-2.) You can also check the RX REPORT when it is 
printed automatically. (See "Adjusting the RX REPORT Setting," on p. 6-6.)
