Abstract
A printer includes a tractor unit for feeding continuous form paper, encoders driven in synchronization with the tractor unit, and detecting sensors for detecting the encoders to generate feed pulses at a standard interval. The printer further includes a paper top sensor for detecting a leading edge of the continuous form paper to generate paper top signal and is arranged to control the feed of the paper based on the feed pulse generated after the paper top signal. In order to adjust the printing position on the paper in case where the scanning position is misaligned due to a manufacturing error, the position of the detecting sensors is adjustable with respect to the encoders to compensate for the error. Further, the position of the paper top sensor is adjustable with respect to the tractor unit in order to keep the relationship between the feed pulse and the paper top signal unchanged regardless of the adjustment of the detecting sensors.
