Abstract
A print apparatus includes a holding unit to hold a roll sheet obtained by winding a sheet, a driving unit, a separation flapper, a pressure contact roller, a print unit, a displacement sensor, and a control unit. The driving unit rotates the held roll sheet. The separation flapper follows a roll sheet surface to separate the sheet from the roll sheet. The pressure contact roller comes into pressure contact with the roll sheet surface. The print unit prints an image on the sheet supplied by rotating the roll sheet in pressure contact with the pressure contact roller in a forward direction. The displacement sensor detects a separation flapper displacement amount according to separation flapper rotation when the sheet is supplied to the print unit after a roll sheet front end is detected. The control unit stops the roll sheet rotation when the amount of displacement exceeds a threshold.
