2.2.4 Switch, LED PCB (Sub PCB)
The PCB includes ON/OFF switch, FEED/CUT switch and LEDs (Red/Green).
2.2.5 Full Cutter Sensor
The full cutter sensor detects the position of full cutter (mechanical SW).
2.2.6 Half Cutter Sensor
The half cutter sensor detects the position of half cutter (mechanical SW).
2.2.7 Roller Holder Sensor
The roller holder sensor detects the position of roller holder (mechanical SW). This is the dual
contact switch that detects the home position side and the pressure contact side.
2.2.8 Full Cutter Motor
The full cutter motor is the drive power for tape cutting. This is the DC motor of VH (24V) drive
voltage.

The half cutter motor is the drive power for half cutting when a laminated tape cassette is mounted.
This is the DC motor of VH (24V) drive voltage.
2.2.10 Tape Feed Motor
The tape feed motor is the drive power to advance a ribbon and a tape. This is the stepping motor of
VH (24V) drive voltage with 25mm diameter.
2.2.11 Release Motor
The release motor is the drive power to press and release the roller holder against/from the thermal
head. This is the DC motor of VH (24V) drive voltage.
2.2.12 Eject Motor
The eject motor is the drive power to advance a cut tape. This is the DC motor of 5V drive voltage.
2.2.13 Thermal Head
The thermal head is the thin membrane thermal head with built-in driver, which consists of 384 dots
by one row/360 dpi. The drive voltage is VH (24V).
2.2.14 AV Sensor PCB
The reflex photo-interrupter which detects the print starting position on the Avery cassette tape is
mounted on the AV sensor PCB.
