password.
CMYK Abbreviation for Cyan, Magenta, Yellow, and Black.

Color matching Technology for minimizing color discrepancy among different devices such as scan-
ners, displays, and printers.
Compact PDF A compression method for reducing the data amount using the PDF format when
converting color documents to data.
The highest compression efficiency is achieved by identifying the text and image re-
gions and using the resolution and compression method most appropriate for each
region.
The compact PDF format can be selected when converting documents to data using
the scanning functions of this machine.
Confidential communication A function for sending and receiving documents to be viewed only by specific per-
sons. The confidential document is saved in a confidential box in the recipient’s ma-
chine and is not printed when it is received. The received document can be printed
when a specific operation is performed, for example, when the access code for the
confidential box is entered.

variation). An image with small light/dark variation has low contrast, and an image
with large light/dark variation has high contrast.

DHCP Abbreviation for Dynamic Host Configuration Protocol.
A protocol in which a client computer on a TCP/IP network automatically specifies
the network settings from the server.
With collective management of the IP address for DHCP clients on the DHCP server,
you can avoid duplication of an address and build a network easily.
Dialing method There are three types: PB (push-button (tone) dialing), 10PPS (pulse dialing at 10
pps), and 20PPS (pulse dialing at 20 pps).
Direct Inward Dialing (DID) A function that provides numbers for fax and phone functions separately.
In order to use the DID function, one must subscribe for NTT’s DID (modem DID)

shades of gray. Processing is easier than with error diffusion, but this can lead to ir-
regularities.
DNS Abbreviation for Domain Name System.
A system that acquires the supported IP addresses from host names in a network
environment. DNS allows the user to access other computers over a network by
specifying host names, instead of having to use IP addresses that are difficult to re-
member and complicated.
