Patent ID: 8851772

Claim:
A printing apparatus, comprising: a printing unit that forms an image on a web; a first feeding unit that feeds the web in the printing unit; a second feeding unit that feeds the web downstream of the printing unit in a feed direction; a buffer unit that has a buffer plate and absorbs flexure of the web generated by a feed difference between the first feeding unit and the second feeding unit by operating the buffer plate; a first feeding control unit that causes the first feeding unit to execute a deceleration operation for decelerating a feed speed of the web when a trigger for stopping the feed of the web has occurred; and a second feeding control unit that: causes the second feeding unit to execute a first deceleration operation for decelerating the feed speed of the web when the trigger for stopping the feed of the web has occurred, measures, with a sensor, a feed amount of the web fed by the second feeding unit during a period beginning at a first time and until a predetermined time passes, and when the feed amount is larger than a threshold value, changes the first deceleration operation executed by the second feeding unit to a second deceleration operation based on the feed amount, wherein the second deceleration operation is an operation for decelerating the feed speed of the web more than the first deceleration operation.
