OPERATING PRINCIPLES

2.2.7 Paper Cutter Mechanism

The Paper cutter mechanism consists of such main parts as the Cutter motor, left and
right HP sensors (2 pcs. in all), Relay board, Paper eject roller shaft and Paper hold-
down flap in the Cutter unit.
Operation during printing
When the Cutter blade starts cutting, the Paper hold-down flap rises and holds the
paper during cutting. The HP sensors for detection of the Cutter blade position are
installed on both ends of the cutter operation area, detect whether the Cutter blade
operates properly, and displays Cutter position error or Cutter jam error according
to the operating condition.
