Q Are documents being sent at a high resolution?
A It is recommended that you send text only documents
with a lower resolution.
Q Is Error Correction Mode (ECM) set to [On] (when
sending a fax)?
A Because ECM corrects errors during a transmission,
any problems on the line can mean that the
transmission will take extra time. Set ECM TX to [Off ].
(See "ECM TX, " on p. 11-14.)
Q Does the recipient's machine support ECM?
A If the recipient's machine does not support ECM, the
document is sent in normal mode without error
checking.
Q Are the telephone lines in poor condition, or do
you have a bad connection?
A Check if there is a device nearby that interferes with
signal transmission (e.g., microwave oven).
A Lower the transmission speed. (See "Fax Settings, " on
p. 11-37.)
