Abstract
A mechanism for correcting the skew of a without-feed-hole paper fed into a high-speed laser printer has been developed. Our skew correction mechanism changed the load balance of the feed roller according to the paper position detected by an optical sensor. We have experimentally studied the relationship between the load of the feed roller and paper speed. Skew correction control parameters were obtained by these data. We showed that this mechanism can feed a paper accurately regardless of its width.
