Abstract
A sheet feeder control for a plurality of sheet feeding mechanisms. When one of the plural sheet feeding mechanisms is selected, the thus-selected sheet feeding mechanism is driven by the sheet feeding mechanism drive section to feed its sheet to the printing section. The non-volatile memory retains, in a non-volatile manner, the information which specifies the sheet feeding mechanism thus selected before the power supply is turned off. On the other hand, when the power supply is turned on again after its removal, it is detected by the sheet discriminating section whether a sheet is placed in the vicinity of the printing section. When the sheet is detected, its kind is also discriminated. When a sheet is detected in the vicinity of the printing section and its kind is discriminated, the preferential drive mechanism drives the sheet feeding mechanism corresponding to the sheet so that the sheet is fed to the printing section. When no sheet is detected by the sheet discriminating section, on the other hand, the preferential drive section drives the sheet feeding mechanism corresponding to the information stored in the non-volatile memory so that a sheet corresponding to the sheet feeding mechanism set before the removal of the power supply is fed to the printing section.
