R
Resolution
The density of dots attained by a 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.
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 actually scanned is slightly smaller than the size of the original document.
Therefore, words or images near the edges of the document may not be scanned. As
a result, make sure that there is some margin space on all sides of the document you
are sending.
Sender's Name
Your personal or organization's name. The sender's name, fax number, date, and time
are printed on each page you send to the recipient. You can register up to 99 sender
names.
