(5) Sensors
The following 4 sensors are used:
Sensor name Description
Head Up Sensor
(SA Head Up SW)
This is a mechanical switch to detect the head
open/close status.
Transparent sensor (SA Adjust Sensor U):
Consists of 1 phototransistor.
Adjustable Sensor
(Consists of the transparent sensor
and reflective sensor.)
Reflective sensor (SA Adjust Sensor L):
Consists of 1 reflective type photointerrupter.
Thermal Head Temp. Sensor Two thermistors are incorporated in the “SA2 Head”.
(6) Unit, Motor
This is a stepping motor to feed media.
(7) Serial I/F (RS-232C)
This is a circuit to transmit and receive serial data between the printer and a host.
Serial I/F, USB I/F or parallel I/F (option) is automatically selected when data is received.
(8) USB (Universal Serial Bus) I/F
This is a circuit to transmit and receive serial data between the printer and a host through USB.
Serial I/F, USB I/F or parallel I/F (option) is automatically selected when data is received.
(9) Parallel I/F (IEEE1284) (Option)
This is a parallel I/F to transmit and receive parallel data between the printer and a host. It
supports Centronics Compatible mode, NIBBLE mode and ECP mode.
Parallel I/F, serial I/F, or USB I/F is automatically selected when data is received.
(10) Ethernet Board (Option)
This is a circuit which supports Ethernet protocol. LAN connection is possible.
