12, 22, 21, 11 1:2, 2:2, 2:1, 1:1	These terms usually refer to the copying combination of originals and copies.  For example, 12 and 1:2 refer to making a double-sided copies of single-sided originals.  On some machines, 1:1 refers to making copies at 100% of the size of the originals, as opposed to reducing or enlarging the originals.
A4, A3, ... B4, B3, ...	These are terms used for standard sheet sizes in most countries of the world.  An A4 sheet is slightly narrower and longer than an 8.5x11 inch sheet.  For more information refer to the excellent summaries of ISO Paper Sizes.
Activity Report	Many fax machines can produce a periodic record of the incoming and/or outgoing faxes for use in accounting or other record-keeping.  This is separate from a "confirmation report" for an individual fax transmission.  Typically several dozen transactions are listed. Printing of these can be turned off if not routinely used.
Analog Copying	DEFN
Automatic Duplexing	A machine that does automatic duplexing turns over the output internally to make double-sided output without the user being involved. This distinguishes it from manual duplexing.
Automatic Shut-off	To conserve energy once copies are made, the copier -  after a preset standby period - will automatically shut off.

C
CPM copies per minute	Copies per minute. Used to measure a copier's speed. "CPM" usually measures the speed at which a copier copies onto one side of 8.5x11 inch or A4 size paper. See speed.
Copying Copiers	DEFN
Confirmation Report	A one-page record that an outgoing fax did or did not go through.

 
 

D
Default Duplex	The standard setting for a default duplex printer or copier is to produce double-sided copies.  Single-sided copies can be selected w hen desired.  On some default duplex copiers, copies off the platen glass are made single-sided, with those from the document feeder double-sided.  Default duplex copiers are usually 1:2, but can be 2:2.
Device	See imaging device.
Digital Imaging Digital Copiers	Conventional copiers use analog imaging in which the image is transferred to paper via a photographic-like process.  By contrast, digital copiers first scan the original like a fax machine into memory, then print it like a laer printer.  Computer printers and copiers are always digital devices.  Digital imaging devices can offer paper-efficiency capabilities that analog copiers cannot.
Document Feeder	A document feeder is a device on top of a copier that will automatically bring individual sheets down onto the platen glass for imaging.  Some document feeders can turn over originals to be able to automatically copy duplexed originals.
Duplexing Duplex Copying Duplex Printing	Imaging on to both sides of a piece of paper.  This usually implies automatic duplexing which requires extra hardware in the copier or printer.  The rare alternative is manual duplexing.
Duplex Faxing	The ability of a fax machine to facilitate faxing double-sided originals.  On conventional fax machines, the originals are fed through twice with the machine rearranging the images in the proper order before transmission.  Multi-function devices with fax capability generally utilize a document feeder that can turn over the paper to scan both sides.  Unlike duplex copying (in which duplexing refers to the result), 'duplex faxing' refers to the ability to properly fax a duplexed original.
Duplexing Rate	The fraction of images that are on sheets of paper imaged on both sides. Duplexing rates are usually measured over a period of time for one or more pieces of imaging equipment.  As an example, three images  with two on one sheet and one on another result in a duplexing rate  of 67%.
Duplexing Speed	The speed at which an imaging device makes duplexed copies.  Speed ratings are always measured with respect to images, not sheets of paper.  For example, a printer that prints at 10 images per minute on 5 sheets of paper has a duplexing speed of 10 ppm.  Many printers and copiers have a lower duplexing speed than their basic (simplex) speed, though some are just as fast.  For copiers, the speed of the document feeder affects the duplexing speed, so copies are not always made at the same speed from single-sided originals as they are from double-sided originals.

 
 

E
Efficiency	The copier's actual running speed when running certain jobs, expressed by BLI as percentage of the copier/s rated speed.
Energy-Saver mode	After a preset time period has elapsed during which no copies are made and/or no control panel adjustments are made, most copiers today will automatically go into a standby mode in which only partial fusing heat is maintained so that energy is saved and a full warm-up period is not necessary for the next copy job.
Energy Star	The Energy Star program is sponsored by the U.S. Environmental Protection Agency and the U.S. Department of Energy.  It is a voluntary program that works with manufacturers of office equipment (and other uses of energy) to encourage the marketing and purchase of devices that have energy-saving features.  There are Energy Star programs for copiers, printers, fax machines, and multi-function devices.  The program is designed to reduce the use of energy, the emission of greenhouse gases, and to save consumers money.

 

F
First copy	The time (measured in seconds) it takes for the first copy to be produced after the print button is pressed.

 

G
GGG

 

H
Half-used paper	Paper that has been used on just one side with the other side blank and suitable for single-sided imaging in a copier, printer, or fax machine.  "Reuse" of paper, which using half-used paper is, is quite different from recycling paper.

 

I
Image Combination	"2 in 1" copying means automatically copying two (or more) originals onto one side of one sheet, usually reducing their size.  The number of images is cut in half.  Can be used with duplexing to get four images on one sheet.  "4 in 1" and greater image combination is possible with printers and digital copiers.  On printers, image combination is often called 2-up (or n-up) printing.
Images per Minute ipm	See speed.
Imaging Device	An imaging device can be a copier, printer, fax machine, or multi-function device.

M
Manual Duplexing	Printing or copying onto both sides of a piece of paper by the user physically moving sheets from the output tray to an input tray, either one at a time, or as a stack.  Since this is tedious at best, only a tiny fraction of duplexing is done with manual duplexing; the rest is done with automatic duplexing.
Mopying	A term invented by Hewlett-Packard, Inc. to refer to "Multiple Output Printing".  Refers to printing many copies of something rather than printing one copy on a printer and using that as the master to create many copies on a copier.  XXXX
Multi-Function Device MFD	The U.S. EPA defines a multi-function device as one that can do copying as well as at least one other function such as printing, faxing, or scanning [CHECK].  Others define MFDs somewhat differently, but a key fact about MFDs is that they are always digital imaging devices and so can have abilities that conventional analog copiers cannot.  Small MFDs derive from fax machines and small printers.  Large MFDs derive from digital copiers.

ppm pages per minute prints per minute	"ppm" usually measures the speed at which a printer prints onto one side of 8.5x11 inch or A4 size paper.  "page" in this case refers to the side of a sheet of paper, not the whole sheet.  See speed.
Printer	DEFN
Printer Drivers	Printer drivers are loaded onto the computer and convert the computer's software description of a document into whatever page description language or protocol the printer uses.
Productivity	The copier's actual copy output speed when completing certain types of jobs, expressed using the total time required and/or a speed rating in copiers per minute. This term can also be used more generally to take into account all the factors contributing to the copier's ability to reduce operator involvement.

R
Rated Speed	The vendor's claimed maximum copy output speed when feeding 8-1/2" x 11" paper
Ream	Five hundred sheets of paper; a standard term used in paper packaging
Recirculating  Document Handler  (RHD/RDF)	? BLI? This device feeds originals from a stack to exposure glass and brings them back to the feed tray for another copy run of the set if required. When used in conjunction with a moving finishing tray (it shifts from side to side), separate stacks of copied sets can be automatically produced. Thes eliminates the need for a sorter and enables much higher productivity when producing long-run jobs (greater than 40 sets at a time). Compared with RADFs, RDHs are not as tolerant of imperfect originals and most cannot handle 11" x 17" originals.
Records	Information stored on some material, often paper, but increasingly digital electronic media such as magnetic tape or CD-ROMs.

 
 

S
Simplex Copy	A sheet that is only printed on one side.
Speed	The speed of an imaging device can be measured as cpm (copiers), ppm (printers and faxes), or ipm (multi-function devices), all of which count the number of images made each minute.  It is usually the maximum speed making images on just one side of 8.5x11 inch or A4 size paper.  A duplexed sheet has two images, though even so, most equipment is slower when duplexing.
