Transmitting
ECM mode
The machine can transmit documents using the ECM mode.
Use the ECM Mode user option (No. 27) to determine whether
the machine transmits a document in the ECM mode.
During an ECM communication, the machine stores and
transmits a document by section, and monitors the transmit
signals on the telephone line. If the machine detects an error, it
can resend the section of the document that was transmitting
during the error.
Automatic redialing
The machine redials a number if a communication does not
complete successfully for one of the following reasons:
• The machine detects a busy signal at the remote
machine. The machine enters a redial wait mode then
redials.
• A communication error occurs during a transmission.
The machine transmits the document beginning with the
first page that did not transmit successfully.
The Number of Redials user option (No. 11) determines the
number of times the machine tries to redial a number. This user
option is subject to regulatory restrictions.
