Abstract
Abstract A recording apparatus such as a laser beam printer has a laser beam unit for forming an image, a cassette for automatically feeding paper sheets, a manual insertion port for allowing manual insertion of paper sheets, a switch to allow selection of the cassette sheet feed or manual insertion sheet feed at the side of the printer, a timer to count a predetermined period of time, and a CPU for switching from the manual insertion sheet feed mode to the cassette sheet feed mode when no paper sheet is manually inserted in the manual insertion sheet feed mode after the time in the timer has elapsed. Undesired accumulation of data designating printing in the cassette sheet feed mode is prevented.
