ECM (Error Correction Mode) and Page Retransmission
ECM is a signaling system that greatly reduces the chance of data being lost
because of a bad telephone line. ECM is useful if you frequently communicate
over poor telephone lines.
With ECM switched on, the communication cost will increase if the line is bad,
but the data will be sent much more reliably.
If ECM is switched off, Page Retransmission will be used. The whole page will be
resent (unless you used Immediate Transmission, in which case damaged data
cannot be resent at all). ECM is more efficient, because it only resends the
damaged parts of the data, and the maximum possible number of retransmission
attempts is much higher, and it also works with Immediate Transmission.
If you prefer reliable communication over communication costs, keep ECM
switched on. If you however prefer to be cost effective, ask the service technician
to switch ECM off.
Pages can be sent up to 3 times before the machine gives up. If you wish to
change the number of retries, contact a service technician.
ECM is switched on in your machine when it leaves the factory, to provide you
with the ability to send accurate and complete documents as reliably as possible.
