during continuous printing. A specific small amount of ink is discharged into

the Cap according to the Periodic flushing timer.

This is done to prevent ink viscosity in the Printhead nozzles from increasing

during continuous printing. A large amount of ink is discharged into the Cap

according to the Periodic large-amount flushing timer.

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.

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.
