If the recipient reports issues with the quality of the fax, try changing the resolution or contrast

of your fax.

Error Correction Mode (ECM) prevents loss of data due to poor phone lines by detecting errors that occur

during transmission and automatically requesting retransmission of the erroneous portion. Phone charges

are unaffected, or might even be reduced, on good phone lines. On poor phone lines, ECM increases sending

time and phone charges, but sends the data much more reliably. The default setting is On . Turn ECM off only

if it increases phone charges substantially, and if you can accept poorer quality in exchange for reduced

charges.
If you turn ECM off:

●

The quality and transmission speed of faxes you send and receive are affected.

●

The Fax Speed is automatically set to Medium .

●

You can no longer send or receive faxes in color.

From the printer control panel display, touch Fax .

Touch Setup .

Touch Preferences .

Scroll to Error Correction Mode and touch to turn the feature on or off.

You can receive faxes automatically or manually. If you turn off the Auto Answer option, you must receive

faxes manually. If you turn on the Auto Answer option (the default setting), the printer automatically

answers incoming calls and receives faxes after the number of rings that are specified by the Rings to

Answer setting. (The default Rings to Answer setting is five rings.)
If you receive a Legal-size or larger fax and the printer is not currently set to use Legal-size paper, the printer

reduces the fax so that it fits on the paper that is loaded. If you have disabled the Auto Reduction feature,

the printer prints the fax on two pages.

If you are copying a document when a fax arrives, the fax is stored in the printer memory until the

copying finishes.

When you are on the phone, the person you are speaking with can send you a fax while you are still

connected. You can pick up the handset to talk or listen for fax tones.
