Abstract
Official abstract text for this publication.
A printing apparatus includes a belt mover for an endless belt that transports a recording medium, a feed amount calculator that calculates an amount of feed of the belt mover, a movement amount detection sensor as a movement amount measurer that measures actual amount of movement of the endless belt by image processing, a compensation table storer that stores a compensation table for compensating a transport error of the endless belt, and a control portion that calculates the amount of feed that is to bring about a predetermined amount of movement of the endless belt by using the feed amount calculator and by referring to the compensation table storer, moves the endless belt by using the belt mover on the basis of the amount of feed, compares the actual amount of movement of the endless belt measured by the movement amount detection sensor and the predetermined amount of movement.
First claim
Opening claim text (preview).
What is claimed is: 1. A printing apparatus comprising: a belt mover for an endless belt that transports a recording medium; a feed amount calculator that calculates an amount of feed of the belt mover; a movement amount measurer that measures actual amount of movement of the endless belt by image processing; a compensation table storer that stores a compensation table for compensating a transport error of the endless belt; and a control portion that calculates the amount of feed that is to bring about a predetermined amount of movement of the endless belt by using the feed amount calculator and by referring to the compensation table storer, moves the endless belt by using the belt mover on the basis of the amount of feed, compares the actual amount of movement of the endless belt measured by the movement amount measurer and the predetermined amount of movement, and determines whether a difference greater than or equal to a predetermined value has occurred between the actual amount of movement and the predetermined amount of movement. 2. The printing apparatus according to claim 1 , further comprising a notification portion, wherein the control portion notifies the notification portion of an alarm if the difference greater than or equal to the predetermined value has occurred. 3. The printing apparatus according to claim 1 , wherein the control portion updates the compensation table if the difference greater than or equal to the predetermined value has occurred.
