Use Error Correction Mode; Set The Fax Speed - HP 1240 Series User Manual

use error correction mode

Error Correction Mode (ECM) eliminates data lost 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. Turn
ECM off (the default setting is on) only if it increases phone charges
substantially, and you can accept poorer quality in exchange for reduced
charges.
Note:
then ECM is always On.
ECM only affects faxes that are being sent

set the fax speed

You can set the fax speed used to communicate between your HP Fax and other
fax machines when sending and receiving faxes. The default fax speed is Fast.
In certain environments, setting the fax speed to a slower speed might be
required. For example, if you use one of the following:
• an Internet phone service
• a PBX system
• Fax over Internet Protocol (FoIP)
•
an integrated services digital network (ISDN) service
Also, if you experience problems sending and receiving faxes, you might want
to try setting the Fax Speed to Medium or Slow. If you want to send with ECM
turned off, you must use Medium or Slow. The following fax speeds are
available.
