Send a fax in Error Correction Mode
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 unaected, 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 o only
if it increases phone charges substantially, and if you can accept poorer quality in exchange for reduced
charges.
If you turn ECM o:
● The quality and transmission speed of faxes you send and receive are aected.
● The Speed is automatically set to Medium .
● You can no longer send or receive faxes in color.
To change the ECM setting from the control panel
1. From the printer control panel display, touch Fax .
2. Touch Setup .
3. Touch Preferences .
4. Scroll to Error Correction Mode to touch to turn the feature on or o.
Receive a fax
You can receive faxes automatically or manually. If you turn o 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 specied by the Rings to Answer setting.
(The default Rings to Answer setting is ve 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 ts on the paper that is loaded. If you have disabled the Automatic Reduction
feature, the printer prints the fax on two pages.
NOTE: If you are copying a document when a fax arrives, the fax is stored in the printer memory until the
copying nishes.
