a. Paper feed
The offset roller [1] is driven by the feed motor (M2). When prescribed time lapses after paper is fed by the feed roller [2], the offset solenoid [3] is turned off to
bring the offset roller [1] into contact with the paper, feeding the paper toward the track tray along with the feed roller [2]. When the trailing edge of the paper leaves
the feed roller, the paper is then fed only by the offset roller [1].
