There are two types of the roll feed unit. B435 Roll feed unit has one roll feed unit
(1st [A]). B436 Roll feed unit has two roll feed units (1st [A] and 2nd [B]). The cutter
unit [C] uses a sliding rotary cutting blade.
When turning on the main switch or when roll paper is replenished, the roll feed
motor rotates and the leading edge of the roll paper is fed until the roll lead edge
sensor [D] is activated. Then, the leading edge of the roll paper is returned to the
paper feed start position (60 mm before the cutter unit).
