Abstract
In one example, an apparatus includes a transparent platen to receive a document to be scanned. The transparent platen includes a scan line, an ingress edge positioned prior to the scan line in the document path, and a chamfered egress edge positioned subsequent to the document path. A light source is positioned to illuminate the document with light while the document passes across the scan line, and a focusing mechanism is positioned to focus a portion of the light that is reflected by the document onto a sensor that senses the portion of the light.
