The pick up and feeder of the printer consists of a roll unit and a
feeder unit.
The roll unit can supply both the roll paper and fan fold paper. The
roll drive shaft rotates to hold and feed the paper. The roll drive shaft
is driven by rotations of the roll motor. Quantity of paper supplied
is detected with the roll sensor to ensure that the required paper
feeding is kept. In case of the fan fold paper, the paper can be
supplied by removing the roll unit drive system and setting the dip
switch on the roll holder PCB. The paper supplied is fed on the
feeder belt of the feeder unit. The feeder belt is driven by the
rotations of the feeder motor in the feeder unit.
The start position of printing is sensed by the TOF inlet sensor 1 or
2, and poor feeding of the paper is sensed by the TOF inlet sensor
1or 2, and the TOF outlet sensor 1 or 2.
