ECM
Error Correction Mode. Reduces system and line errors when sending or receiving
from another fax machine with ECM capability. ECM divides a page into blocks and
inspects each block for data lost through poor transmission. If part of the data is
missing in a certain block, ECM retransmits that data from the beginning of the block
until it confirms that all the data within the block has been transmitted successfully. In
this way, ECM guarantees that a good image can be received at the receiving end.
ECM is very effective where the telephone lines are in poor condition. However, ECM
slows the transmission speed, and you may turn this mode off, if it is not needed.
