发明名称 Image forming apparatus and control method thereof
摘要 An apparatus comprises an accommodation unit which accommodates a continuous printing sheet; a conveyance unit which conveys the printing sheet; a printing unit which performs image forming processing on the conveyed printing sheet; a cutting unit which cuts the printing sheet after completion of the image forming processing; and a processing unit which executes, when a printing sheet remaining on a conveyance path is detected, processing for removing the remaining printing sheet, the processing unit controls the conveyance unit to convey the printing sheet to detect a leading end, compares a first distance from the leading end to a portion located at a curl correction unit with a second distance from the leading end, which distance is required for image forming processing set, and sets a larger distance as a cutting position of the remaining printing sheet.

主权项 1. An image forming apparatus comprising: an accommodation unit configured to accommodate a continuous printing sheet wound in a roll shape; a conveyance unit configured to pull out and convey the printing sheet from said accommodation unit; a printing unit configured to perform image forming processing on the printing sheet which is conveyed by said conveyance unit to an image forming start position; a cutting unit configured to cut the printing sheet after completion of the image forming processing at a predetermined cutting position; and a processing unit configured to execute, when a printing sheet remaining on a conveyance path is detected at an activation timing, processing for removing the remaining printing sheet, wherein said processing unit controls said conveyance unit to convey the printing sheet at the activation timing to detect a leading end of the printing sheet, compares a first distance from the leading end to a portion which was located at a curl correction unit before the activation with a second distance from the leading end, which distance is required for image forming processing set before the activation, and sets a larger distance of the first and the second distances as a cutting position of the remaining printing sheet.
