Patient interface

A scanner assembly includes an automatic document feeder and a first scanner. The automatic document feeder defines a media pathway that includes an input portion and an output portion having an exit roller. The first scanner is positioned along the media pathway upstream from the exit roller. In a first assembled configuration, the assembly is configured to scan both a first side and a second side of the media via the first scanner. In a second assembled configuration, the assembly additionally includes a second scanner positioned along the output portion and interposed between the first scanner and the exit roller. In the second configuration, the assembly is configured to scan the first side of media via the first scanner and to scan the second side of media via the second scanner.

Configurable scanner assembly

An automatic document feeding device including a pick motor coupled with a pick assembly, a deskew motor coupled with a deskew assembly, a sensor assembly coupled with a main media path and the deskew motor, and a feed motor coupled with a feed assembly. The deskew motor drives the deskew assembly, the deskew assembly deskewing the media sheet and moving the media sheet from the pick assembly to the feed assembly, the deskew assembly moving independently of the pick assembly and the feed assembly. The sensor assembly includes a plurality of sensors. The sensor assembly senses the media sheet moving along the main media path and sends at least one signal to a computer. The computer, based on the at least one signal, sends, an activation signal to at least one of the pick, deskew and feed motors and the first scanner.

Automatic document feeder

An automatic document feeder with a drive system that can efficiently handle double-side scanning and accommodate more than one timing sequence for sequentially picking individual sheets from a stack using only two motors&#x2014;a pick motor and a media motor. The automatic document feeder includes a pickup unit with a pick roller, a set of de-skew rollers, a main media path configured to guide a media sheet from the pickup unit to a scanning region and from the scanning region to an output tray, and a switch-back path configured to guide the media sheet back into the main media path. The drive system is operable to provide a high-speed picking mode and a delayed picking mode. In the high-speed picking mode, the pickup unit is driven by the pick motor to pull a subsequent media sheet from a stack of media sheet as soon as a previously pulled media sheet has passed the pick roller. In the delayed picking mode, the de-skew rollers are driven by the pick motor to advance the media sheet toward the scanning region and the subsequent media sheet is pulled from the stack by the pickup unit when the previously pulled media sheet has passed the de-skewed rollers.
