Abstract
A supply roller for sending a piece of sheet from pieces of sheets stacked within a cassette towards a sheet guide and a pair of feed-in rollers for sending the piece of sheet supplied from the sheet guide towards a printing region are provided within a printer. The pair of feed-in rollers has a feed-in drive roller driven by a motor and a feed-in driven roller driven by the feed-in drive roller. A sending speed of the pair of feed-in rollers is faster than a sending speed of the supply roller, and a sending force of the pair of feed-in rollers is stronger than a sending force of the supply roller. A controller of the printer controls the rotation of the supply roller and the pair of feed-in rollers according to a procedure that does not rely on a position of the sheet sent by the supply roller and the pair of feed-in rollers during the continuous feeding mode.
