The SR-6500 can process either 3,500 or 5,500 forms per hour. These two workhorses have the ability to read full page forms, with up to 48 columns and 109 lines or 5,232 markings. You can double this capacity by adding the duplex read head option, permitting the scanner to read both sides of the form in one single pass.

The SR-6500 use OMR (Optical Mark Recognition) technology which has an error rate of less than 1%. OMR is the preferred method to scanning forms as it processes forms at a relatively high speed, is dependable, and requires very little human intervention.
