D
Delayed Transmission
Also called "Delayed TX." By setting a time for the document to be sent, you do not
have to be present at that specific time in order to send your facsimile. You can
reserve up to 64 delayed transmissions.
Direct Sending
Use Direct Sending when the memory is full but you still need to send a document.
Direct Sending scans and sends one page at a time, without the need for the
document to be stored in the memory.
DNS server
Domain Name System server. A server which maintains a database that translates
the domain names of Internet servers, such as www.w3.org, into Internet Protocol(IP)
addresses, such as "18.176.0.26". This enables clients to connect to a server with a
host name rather than a numeric IP address.
dpi
Dots per inch. A measure of screen and printer resolution that is expressed as the
number of dots that a device can print or display per linear inch.
E
ECM
Error Correction Mode. ECM divides a page into blocks and inspects each block for
data lost through poor transmission. If a part of the data is missing in a certain block,
ECM re-transmits that data from the beginning of the block until it confirms that all the
data within the block has been successfully transmitted. In this way, ECM is very
effective where telephone connections are poor. However, because ECM slows down
the transaction speed, you may prefer to turn it off if it is not needed.
Error Lamp
The error lamp flashes when the available memory is low or when there is no paper in
the paper drawer.
F
File formats
File formats used to save image data. This machine supports two different file
formats, TIFF and PDF.
