Fuser Unit - Samsung ProXpress C401 series User Manual

An emulator duplicates the functions of one system with a different system, so that the second system behaves
like the first system. Emulation focuses on exact reproduction of external behavior, which is in contrast to simu-
lation, which concerns an abstract model of the system being simulated, often considering its internal state.
Ethernet
Ethernet is a frame-based computer networking technology for local area networks (LANs). It defines wiring
and signaling for the physical layer, and frame formats and protocols for the media access control (MAC)/data
link layer of the OSI model. Ethernet is mostly standardized as IEEE 802.3. It has become the most widespread
LAN technology in use during the 1990s to the present.
EtherTalk

Fuser Unit

The part of a laser printer that fuses the toner onto the print media. It consists of a heat roller and a pressure
roller. After toner is transferred onto the paper, the fuser unit applies heat and pressure to ensure that the
toner stays on the paper permanently, which is why paper is warm when it comes out of a laser printer.
Gateway
A connection between computer networks, or between a computer network and a telephone line. It is very
popular, as it is a computer or a network that allows access to another computer or network.
Grayscale
A shades of gray that represent light and dark portions of an image when color images are converted to gray-
scale; colors are represented by various shades of gray.
Halftone
An image type that simulates grayscale by varying the number of dots. Highly colored areas consist of a large
number of dots, while lighter areas consist of a smaller number of dots.
Mass storage device (HDD)
Mass storage device (HDD), commonly referred to as a hard drive or hard disk, is a non-volatile storage device
which stores digitally-encoded data on rapidly rotating platters with magnetic surfaces.
