R
Random Access Memory (RAM)
The working memory of the computer in which programs and data are temporarily stored 
while you use them. Resetting or shutting off the computer clears all information from RAM. 
Printing very complicated documents might require closing other running programs or adding 
more RAM to the computer. See also Physical RAM, Virtual memory.
Resolution
The density of dots for any given output device, expressed in terms of dots per inch (dpi). Low 
resolution causes font characters and graphics to have a jagged appearance, but prints faster 
than higher resolutions. Higher resolution provides smoother curves and angles as well as a 
better match to traditional typeface designs, but prints more slowly. This printer can produce 
output with 300 or 600 dpi resolution. Resolution values are represented by horizontal data 
and vertical data, for example, 600 x 600 dpi.
Reverse Output Order
This function allows printing pages of the document in reverse order: from the last page to the 
first page.
S
Scalable fonts
Scalable fonts allow characters to be printed in various sizes and rotation angles. This is 
different from bitmap fonts, which are printed in fixed sizes and angles.
Scaling
Enlarging or reducing the printed image.
Separator page
Optional pages printed at the beginning of each document to help separate one print job from 
another.
Server
A network computer that is directly attached to the printer. The server controls the printer and 
handles print jobs sent from the clients. See also Client.
Shielded
A type of cable that contains a metallic sheath over the conductor material to protect the data 
passing through the cable from electromagnetic interference. You need to use a double-
shielded interface cable with this printer.
Spooling
A process by which an application sends a document to the Spooler, rather than directly to the 
printer, thus freeing the computer and application for other tasks. Spooled documents are 
printed in the order they are received.

Start menu
The menu that presents commands that are a starting point for all work you do on your 
computer, such as starting a program, opening a document, finding a file, and getting help. 
You open the Start menu by clicking the Start button displayed on the Desktop.
Status options
Settings which determine when the Printer Status Window opens and whether sounds play 
with messages.
Status Window
A window that the Canon Advanced Printing Technology uses to display messages about the 
current print job, as well as to graphically show the print job’s progress from computer to 
printer.
T
Title bar
The horizontal bar that contains the title of a window or dialog box. On many windows, the 
title bar contains the Control menu box and Maximize and Minimize buttons.
Toner
A black, resin-coated powder contained in the Cartridge L50. The printer applies the toner to 
the surface of the photosensitive drum inside the printer via an electrophotographic 
mechanism.
Toner saver
Because the black areas of print data are thinned, toner consumption is reduced.
Tool bar
In the Status Window, the area in the tab window that includes buttons for pausing, resuming,  
and deleting the current print job.
Transfer roller
Presses the paper against the drum, to aid the transfer of toner to the paper.
Trouble Shooter
A program that helps you solve printing problems. The Trouble Shooter checks the 
Windows configuration settings, and if possible corrects any errors that it finds.
TrueType fonts
Scalable fonts used for both screen display and printing. TrueType fonts can be sized to any 
height, and print exactly as they appear on the screen, but with higher resolution.

U
Universal Serial Bus (USB) interface
These are new serial interface standards. This bus automatically recognizes connections (Plug 
and Play) to allow plugging and unplugging connectors with the power still turned on to the 
PC or peripheral equipment.
V
Virtual Memory
Space on the hard disk that Windows uses for temporary data storage as if it were actually 
random access memory (RAM). Windows does this by means of a swap file. This provides 
Windows with more usable memory, but reduces speed of access to it when the swap file must 
be used. See also Physical RAM.
W
WebNetSpot
This utility is used to control network printers.
Weight
Refers to the thickness of a font: light, medium, or bold. Also refers to the thickness of paper.
Windows Explorer
The Windows program you can use to browse through, open, and manage the disk drives, 
folders, and files on your computer in a network system. You can also use Windows Explorer 
to view and open shared folders on other computers on the network. You can use Windows 
Explorer to manage your files by moving, copying, renaming, and deleting files.
WYSIWYG
Pronounced wizzy-wig, an acronym for “what you see is what you get.” For example, when 
you format a paragraph, the line breaks that appear on the printed page are exactly the same as 
they are on the screen.
