AUTOMATIC EXPOSURE CONTROL
Automatically adjusts the amount of light necessary to properly expose the selected original. (i.e., colored paper, poor quality original)

ANALOG COPIER
Lens and mirrors are the components of the conventional analog copier that transfers the scanned image to a photoconductor. The mirrors direct the light through the lens and then to the drum.

AUTOMATIC DOCUMENT FEEDER (ADF)
A device that holds a stack of originals and feeds them automatically, one at a time to the exposure glass for scanning/copying.

AUTOMATIC POWER SAVE MODE
There are 2 user settings for power off or sleep mode (low heat) after 90 seconds of no copier activity.

AUTOMATIC START
Allows the user to enter copy functions/commands during the warm-up period. After warm-up is completed, copying will begin automatically.

CARTRIDGE EXCHANGE SYSTEM
An easy to replace, single cartridge system, for the toner and developer.

CONTINUOUS COPIES
Ability to make copy after copy without the operator having to press the start key at the end of each copy cycle. The number of continuous copies, varies by model.

CONTINUOUS MODE
Enables copier to continue producing photocopies until it runs out of paper.

COPY SIZE
Both the minimum and maximum copy area, and paper size that the copier can utilize.

CPM
Copies Per Minute.

DEVELOPER
The substance that carries the toner in the developer unit. Through the friction of the developer, the toner particles are negatively charged, which will cause attraction to the positively charged drum.

DEVELOPMENT
Process by which toner is applied to the image on the photoconductor drum.

DEVELOPMENT SYSTEM
There are two types of development systems in use today in personal/desktop copiers: 1. Dual-component using a magnetic brush 2. Mono-component using a magnetic roller

DIGITAL COPIER
Uses an array of sensors that scan the image of a document and prepare it for digital processing.

DRUM
The heart of a copier on which the image is formed. It consists of an aluminum core with multiple layers of light and charge sensitive material such as selenium, or an organic based material.

ENERGY SAVE MODE
An energy conserving feature where after copying and a preset time period, the copier automatically goes into a standby mode in which partial fusing heat is maintained so that a full warm-up period is not necessary for the next copy job.

ENLARGEMENT
Ability to increase the size of the image of the original on a photocopy.

FIRST COPY TIME
Time required from when the start key is pressed to the time the first copy arrives at the exit tray.

FUSING
Process used to permanently affix the toner particles to the copy paper. Most commonly, heat and pressure applied by a heat lamp inside two rollers.

GRAPHICAL DEVICE INTERFACE (GDI)
Allows the copier to become a Windows printer.

MANUAL BYPASS
Allows the user to copy onto different paper stock, without changing paper cassettes or trays. Also used for two-sided copying.

MAXIMUM ORIGINAL SIZE
Largest original that can be placed on the glass and copied.

MAXIMUM COPY / PRINT SIZE
Largest size paper that can be put through the machine.

MULTI-COPY
Greatest number of copies that the copier can be programmed to produce, from one original. Note: differs by model.

MULTI-COPY / PRINT SPEED
Number of copies per minute produced from one original in a continuous run after the first copy exits. This is also the maximum copy output speed of the machine.

OPTICS
Lens and Mirrors: These are the components of the conventional analog copier that convey the scanned image from the glass to the photoconductor drum. The mirrors direct the light through the lens (for focusing or magnification) to the drum.

FIBER OPTICS
Some copiers use fiber optics - layers of Lucite fibers sandwiched together which transmit light to the drum to form an image. Fiber optics are less expensive and easier to manufacture than optical lenses, and they allow for the production of smaller-sized copiers.

PAPER CAPACITY
Maximum amount of paper copier can store in the paper tray.

PAPER TRAY
Removable cassette, where blank paper is stored for copying.

PAPER WEIGHTS
Thickness of paper(s) that is recommended for use in the copier.

PHOTO MODE
The ability of the copier to copy halftones or photographs more clearly.

PLATEN
The platen (or exposure glass) is the plate of glass upon which the original is placed for copying. There are two types of platens:

Moving: The platen moves from side to side, carrying the original over the optics. Copiers with moving platens usually have speeds of less than 20 copies per minute.
Stationary: The platen remains stationary while an internal scanning device moves from side to side to copy the original. This feature usually makes a machine physically larger but gives user the option of adding a document feeder, which can not be used on a copier with a moving platen.
Note: When determining the amount of space needed for a copier, the user must take into account whether or not, they need to allow extra room for the moving platen.

REDUCTION
Function which allows the operator to decrease the size of the image on the copy paper.

SINGLE DOCUMENT FEEDER (SPF)
The document must be manually pulled through the feed mechanism each time a copy is needed.

SORTER
A device which is added to an analog copier to collate multiple page output into complete sets.

TONER
Plastic-carbon based substance that forms the image on the paper. Toner is part of a mono-component, or dual- component developing system. It has the appearance of a dry powder.

WARM-UP TIME
Amount of time required for the copier to become operable after being switched on. 
 

ZOOM
"Zoom" reduction or enlargement modes may be selected by the operator in 1% increments. Magnification percentages (+/-) typically range from 25% to 400%.
