ABSTRACT:
In a printing device having at least a pair of sheet discharge rollers for discharging a printing sheet on which a printing operation has been executed, provided are means for judging whether the printing sheet exists or not at a contact position of the pair of sheet discharge rollers, and control means for controlling the pair of rollers so as to be brought out of contact in case that the sheet does not exist at the contact position. Thus, even if the sheet is skewed or bent, it is securely nipped between the pair of sheet discharge rollers, thereby reducing occurrence of a sheet jamming.
