2.2.7.1 Cutter Initialization Sequence
When the Cutter is fitted, the Cutter initialization sequence is executed if the
printer has confirmed that the Cutter has been fitted (the Power Switch blinks
about 5 seconds).
Cutter Initialization Sequence
The initialization sequence is performed to securely put the Cutter Blade in
a standby position detected by the right HP Sensor if the Cutter Blade is
not detected by the right HP Sensor.
The initialization operation is not performed if the Cutter Blade is in the
right HP Sensor position when the Cutter is fitted.
During Cutter operation, Cutter Position Error or Cutter Jam Error may occur.
These errors are explained below.
If the Cutter Blade cannot reach the left or right HP Sensor, the Cutter
Blade is returned to the HP Sensor located in the motion starting position
(right HP Sensor).
Cutter Jam Error
Indicates that the Cutter Blade can return to the HP Sensor position in
the motion starting position within 3 seconds.
Cutter Position Error
Indicates that the Cutter Blade cannot return to the HP Sensor position
located in the motion starting position within 3 seconds.
Paper cutting by the Cutter consists of the basic cutting sequences 1 and 2.
Basic cutting sequences 1
Means movement from the right HP Sensor to the left HP Sensor. At this
time, as soon as the Cutter Blade starts moving from the right HP Sensor,
the Timer starts. If the left HP Sensor does not detect the Cutter Blade
within 3 seconds, the Cutter initialization sequence is executed and then
Cutter Jam Error or Cutter Position Error occurs.
Basic cutting sequences 2
Means movement from the left HP Sensor to the right HP Sensor. At this
time, if the Cutter Blade cannot move from the left HP Sensor to the right
HP Sensor within 3 seconds, Cutter Position Error occurs.
2.2.7.2 Cutter Self-cleaning
This sequence indicates the operation performed to hold down and remove the
ink, which may stick to the Plate above the Paper Hold-down Flap (Plate where
the paper print surface comes into contact), with the leading edge of the fed roll
paper.
The Cutter Blade must be operated left-to-right to operate the Paper Hold-
down Flap. At this time, the Cutter Blade generates operating noise during
Cutter self-cleaning when the roll paper is fed.
2.2.7.3 Cutter Cleaning (Driver Side)
This sequence is executed on the driver side. By cutting the roll paper three
times at intervals of 7cm, the ink that may stick to the Cutter Blade is removed
to clean the Cutter Blade.
