Abstract
A scanning device including a controller and a light source operatively coupled to the controller. The light source is shaped and located such that at least part of the light emitted from the light source is reflected off of a document to be scanned, and the light source has a maximum output when the light source is fully warmed up. The scanning device further includes a receptor operatively coupled to the controller, the receptor being located to receive the light reflected from the document to be scanned such that the at least part of the visual properties of the document to be scanned are transmitted to the receptor in a scanning process. The controller is configured to selectively allow the scanning process to proceed when an output of the light source is less than about 80% of the maximum output.
