Flatbed Scanner

A scanner with a glass surface where a document is placed face down and scanned by a moving sensor.

Definition

Flatbeds scan single pages, books, and photos and are often built into MFDs. Resolution is measured in DPI. Dirt on the glass appears as spots or lines on every scan.

Example

Scan a passport photo at 600 DPI on a flatbed.

Exam tip

Repeated marks on every flatbed scan: clean the glass.
