Resolution
The density of dots attained by an output device, such as a fax, scanner, or printer, in
producing an image. Expressed in terms of dots per inch (dpi). Low resolution causes
font characters and graphics to have a jagged appearance. Higher resolution means
smoother curves and angles, as well as a better match to traditional typeface designs.
Resolution values are represented by horizontal data and vertical data (e.g., 600 x
600 dpi).
RGB
Red (R), Green (G), and Blue (B) are the three primary colors of light. RGB is the
standard color model used in computer/television monitors, scanners, and digital
cameras. RGB is an additive system (colors are added to a black background),
typically produced by emitted light. The RGB color model blends varying intensities of
red, green, and blue light to create colors throughout the spectrum. A combination of
these colors in equal amounts produces white.
RIP
Raster Image Processor. The hardware and software functions of a printer that
convert vector graphic descriptions from a computer into raster graphic images that
can be printed.
Rotary Pulse
Also called "pulse dial." On a rotary pulse telephone, a dial is turned to send pulses to
the telephone switching system.
RX
Abbreviation for "Reception/Receiving."
RX Password
The RX Password is needed to send or receive documents to and from a fax machine
that uses ITU-T standard subaddresses and passwords. If the passwords on both
ends do not match, the fax is not transmitted. Numbers of up to 20 digits, including
spaces, asterisks (*), and pound signs (#), can be used for the RX Password.
S
Scanning Area
The area that is actually scanned is slightly smaller than the size of the original
document, so words or images near the edges of the document may not be scanned.
Therefore, you should allow some margin on all sides of the document that you are
sending.
