for machines equipped with Tag 648 only.
Tag 648 is a field modifcation which was installed on machines in locations where the originals were very thin paper such as onionskin types of paper. The feed head on the Type-B Document Feeder is attached to the upper jam clearance door, so if you lift the door, the feed head goes up with it. The tires are considerably shorter than on the other versions of the feeder.
