TRANSMISSION

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 wish reliable communication and do not mind paying extra communication charges when the line is noisy, keep ECM switched on. However, if you are more worried about communication costs, contact a service technician and ask to have ECM switched off and Page Retransmission switched on.

If Page Retransmission is on, 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.
