Printing apparatus and method for controlling printing apparatus

A printing apparatus comprising:

• a conveyor configured to convey a printing medium;
• an image recording device configured to record an image on the printing medium conveyed in a conveyance direction by the conveyor;
• a machining device provided downstream of the image recording device in the conveyance direction, the machining device being configured to perform one of (i) cutting, (ii) perforation forming, and (iii) fold forming on the printing medium having the image recorded thereon by the image recording device and being conveyed by the conveyor;
• a detector provided upstream of the machining device in the conveyance direction, the detector being configured to detect a trailing end portion of the printing medium;
• and
• a controller configured to cause the printing apparatus to:
• calculate a machining position of the printing medium based on a length of the printing medium, the length of the printing medium being grasped by detecting the trailing end portion by the detector;
• after the calculating, convey the printing medium in a reverse direction by the conveyor to move the machining position to a position of the machining device, the reverse direction being opposite to the conveyance direction by the conveyor;
• and
• after the conveying, perform one of the (i) cutting, (ii) perforation forming, and (iii) fold forming on the printing medium at the machining position on the printing medium by the machining device.

A method for controlling a printing apparatus,

• the printing apparatus comprising:
• a conveyor configured to convey a printing medium;
• an image recording device configured to record an image on the printing medium conveyed in a conveyance direction by the conveyor;
• a divider provided downstream of the image recording device in the conveyance direction, the divider being configured to divide the printing medium having the image recorded thereon by the image recording device and being conveyed by the conveyor;
• a detector provided upstream of the divider in the conveyance direction, the detector being configured to detect a trailing end portion of the printing medium;
• and
• a controller,
• the method comprising:
• calculating a dividing position of the printing medium based on a length of the printing medium, the length of the printing medium being grasped by detecting the trailing end portion by the detector;
• after the calculating, conveying the printing medium in a reverse direction by the conveyor to move the dividing position to a position of the divider;
• and
• after the conveying, dividing the printing medium at the dividing position by the divider.

A method for controlling a printing apparatus,

• the printing apparatus comprising:

• after the calculating, conveying the printing medium in a reverse direction by the conveyor to move the machining position to a position of the machining device, the reverse direction being opposite to the conveyance direction;
• and
• after the conveying, performing one of the (i) cutting, (ii) perforation forming, and (iii) fold forming on the printing medium at the machining position on the printing medium by the machining device.
