E
ECM
Stands for Error Correction Mode. Reduces system and line errors when sending or
receiving from another fax machine with ECM capability. When there is noise on the
telephone line, a distortion or blank area can occur in the document received by the
other party. ECM divides one page into a number of blocks and checks for lost data
block by block. When some data is lost in a certain block, ECM repeats transmission
from the beginning of that block after confirming that all data within the block can be
transmitted successfully. In this way, ECM guarantees that a good image can be
received at the receiving end. ECM is very effective in countries where the telephone
lines are in poor condition. There may be occasions when you want to turn ECM OFF.
For instance, when you feel the transaction speed is extremely slow.
Error lamp
Blinks red when a paper jam occurs or the machine is running out of toner or paper.
F
Fine
Use this setting for documents with very small characters and lines. It is twice the
standard resolution.
G
G3
Group 3 fax machines defined by CCITT/ITU-T. Uses encoding schemes to transmit
image data while reducing the amount of data that needs to be transmitted, thus
reducing transmission time. G3 fax machines can transmit one page in less than one
minute. Encoding schemes for G3 fax machines are Modified Huffman (MH), Modified
Read (MR), Modified Modified Read (MMR), and JBIG.
Group dialing
Group dialing enables you to dial up to 199 previously registered one-touch speed
dialing or coded speed dialing numbers together as a group. This means you only
need to press a one-touch speed dialing key or [Coded Dial] followed by a three digit
code to dial a large group of numbers automatically. You register each group of
facsimile numbers under a one-touch or coded speed dialing key, so make sure a key
is available before trying to register numbers for group dialing. Once a group is
defined, you can add or delete numbers to/from the group.
