Abstract
Automatic sheet feeding of an installed roll is performed more reliably. To this end, a leading end of a sheet is detected on the basis of a change in an output value of a sensor while causing a roll to rotate in a winding direction using a sensor capable of detecting a distance to the sheet separated from the roll. After the detection, the roll is caused to rotate in a feeding direction, and a feeding state of the sheet is determined on the basis of a change in the output value of the sensor.
