Abstract
A printing apparatus includes a printing unit for carrying out a printing mode in which an image formed on a photosensitive unit through an electrophotographic process is transferred to a copy sheet, a reading unit for carrying out a document reading mode in which a document is optically scanned by the reading unit to read image information from the document, a sheet feeding unit for supplying a copy sheet to the printing unit, a sheet transport path usable both for sending a copy sheet present at the reading unit to the printing unit and for sending a document present at the reading unit to a document ejecting portion, a sheet sensor for detecting whether or not a sheet is present at the reading unit, and a control unit connected to the sheet sensor for setting the document reading mode when a sheet at the reading unit is detected, so as to enable the reading unit to read image information from the sheet.
