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.

Reinstall

To remove installed software and install again.

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. Resolution values are represented by horizontal data and vertical data, for example, 600 x 600 dpi.

T

TWAIN (Technology Without Any Interested Name)

Industry-standard protocol for transferring information from devices such as scanners and digital cameras to a computer.

Industry-standard protocol for an application programming interface (API) for input devices such as scanners. If both the device and the application comply with the standard, they will be compatible regardless of differences in manufacturer or model.

For example, with TWAIN-compatible image-processing software, you can start the scanner’s TWAIN driver from the software’s menu, scan the document and return the scanned image to its original image-processing software.

S

Scanner driver

A program that controls how the computer and scanner interact. The scanner driver is provided with two drivers: The TWAIN and the WIA driver (for use with Windows XP).

Scanners and Cameras folder (Scanners and Cameras
