Setting Scan to File Image Resolution
Image resolution deals with the amount of data, or pixels used when scanning an image. The higher the image resolution, the better the
image looks. However, depending on where the image will ultimately be used, you may not need a high resolution image. For example,
if an image will only be viewed on the web, you won't need an image that's 1200 x 1200 pixels. The following will provide guidelines on
image resolutions appropriate for various delivery styles.

Scan to File Resolution
Remote copy is the use of Scan to File for the purpose of reprinting on another Xerox Nuvera system.
A local copy is created using the Copy function on the Xerox Nuvera. The local copy is equivalent to 1200 x 600 dpi scan (chosen for
very high productivity with competitive image quality). Because 1200 x 600 dpi is an asymmetric image which is not conducive to
integration into make ready applications, the 1200 x 600 option is not provided for Scan to File. For particularly stressful documents,
local copy will generally be better than the remote copy.
The Scan to File selection between 600 x 600 dpi and 1200 x1200 dpi is a document dependent one. It is dependent on productivity,
archival file size and image quality requirements. Because the coarseness of the error diffusion (diffusion dither) varies between the two
resolutions, the user is encouraged to try both and evaluate pictorial and business graphic areas for digital grain and text for sharpness.
Chose the resolution best suited for your application. Generally 600 x 600 dpi image quality is preferred for pictorials and 1200 x 1200
dpi for text. The preference will also vary depending upon which mode (text, mixed text and graphics, mixed text and photos) is used.
Remember, documents scanned with higher contrast and lighter (more background washout), will compress better, improving
productivity and storage.
