ABSTRACT:
A light source control method for an electronic copier includes the steps of: detecting a size of a document in response to input of a start key while the copier is in a manual tray copy mode; and moving an exposure lamp a given distance along a length of the document corresponding to the size of the document detected in the detecting step. The given distance equals a predetermined percentage of a reference value representative of a maximum scan distance of the exposure lamp.
