Question Tip

When should I use Text mode?

• Use Text mode when text preservation is the main goal of the scan, and

preserving images copied from the original document is not a concern.

• Text mode is recommended for receipts, carbon copy forms, and documents

that only contain text or fine line art.

When should I use Text/Photo mode?

• Use Text/Photo mode when scanning an original document that contains a

mixture of text and graphics.

• Text/Photo mode is recommended for magazine articles, business graphics,

and brochures.

When should I use Photo mode? Use Photo mode when scanning photos printed on a laser printer or taken from

a magazine or newspaper.
