Control Panel
A control panel is a flat area where control or monitoring instruments are displayed. They are typically found in top or front of the machine.
Coverage
This is the printing term used for toner usage measurement on printing and generally used as 5% coverage. 5% coverage means that an A4 sided paper has about 5% image or text on it. So, if the paper or original has complicated images or lots of text on it, the coverage will be over 5% and at the same time, toner usage will be as much as the coverage.
Default
The first set values.
DPI
This is the measurement of resolution which is used for printing or scanning. Generally, more dots per inch result in a higher resolution, more visible detail in the image, and a larger file size.
Duty Cycle
Duty cycle is the page quantity which does not affect printer performance for a month. Generally the printer has the lifespan limitation such as pages per year. The lifespan means the average capacity of
Fuser Unit
This is the part of a laser printer that melts the toner onto the print media. It consists of two hot rollers. 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.
Grayscale
Shades of gray that represent light and dark portions of an image when color images are converted to grayscale; colors are represented by various shades of gray.
Halftone
This is 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.

A
Print Media
Media such as papers, labels, and transparencies which can be used on a printer, a scanner, a fax or, a copier.
OPC Drum
A mechanism that makes a virtual image for print using a laser beam emitted from a laser printer, and it is usually green or
Portable Document Format (PDF) is a proprietary file format developed by Adobe Systems for representing
PPM
Pages Per Minute. PPM shows the printer's speed, how many pages a printer can actually print per minute.
PRN file
An interface for a device driver, this allows software to interact with the device driver using standard input/output system calls, which simplifies many tasks.
Resolution
The sharpness of an image, measured in dots per inch (dpi). The higher the dpi, the greater the resolution.
Toner cartridge
It is a kind of bottle within a machine like a printer which contains toner. Toner is a powder used in laser printers and photocopiers which forms the text and images on the printed paper. Toner can be melted by the heat of the fuser, causing it to bind to the fibers in the paper.
URL
Uniform Resource Locator (URL) is the global address of documents and resources on the Internet. The first part of the address indicates what protocol to use, the second part specifies the IP address or the domain name where the resource is located.
USB
Universal serial bus (USB) is a standard that was developed by the USB Implementers Forum, Inc., to connect computers and peripherals. Unlike the parallel port, USB is designed to concurrently connect a single computer USB port to multiple peripherals.
