individual computers and users. The Internet is managed by classifying domains
according to geographical location or type (business, organization, educational

number of dots that a device can print or display per linear inch.
E
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.
Error lamp
The error lamp flashes red when a paper jam occurs or the machine has run out of
toner or paper.
F

FTP

computer to and from another computer over a TCP/IP network. The File Transfer
Protocol also governs the client program with which the user transfers files.
