Document
The single sheet or stack of papers containing the data you want to send through or
receive from a fax machine.
Document density
The document density settings alter the lightness or darkness of the documents sent
or received. See density control.
Document output tray
Holds documents ejected from the machine after they have been scanned into
memory, copied, or sent by direct sending.
Dual access
Enables you to scan a document, even if the machine is copying, sending or receiving
a document. You do not have to wait until the machine finishes the current
send/receive transmission. While the machine sends a document from the memory,
you can load other documents into the memory, copy documents, print out reports, or
register information.
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.
F
Fax Basic Features screen
The machine is ON, and ready to use. All operations start from the Fax Basic
Features screen, where the date and time are displayed.
Fine
Use this setting for documents with very small characters and lines. It is twice the
standard resolution.
