What settings affect the speed, or throughput, of my scanner?

Some basic settings that affect the throughput of your scanner speed, rated in pages per minute (PPM) include:

Paper size – the longer the paper, the longer it will take to scan

Paper orientation – documents take longer when scanned in portrait mode; today, many software applications like VRS can be configured to rotate the image as the document is scanned so that they can be scanned long-edge first while displayed on the screen correctly

Resolution, rated in dots per inch (dpi)– the higher the dpi setting, the longer it takes to scan any given page.

Scan mode – documents scan faster in bitonal mode than in grayscale mode
