ABSTRACT:
In a recorder, at least one set of marks spaced by a predetermined distance in a feed direction of a record paper are recorded on the record paper, the marks are detected by a detector while the record paper is fed, a time interval between detections of the marks is compared with a reference number of pulses applied to paper feed motors to detect a deviation, and rotations of the left and right paper feed motors are controlled to control the feed of record medium.
