Chapter 2 Operating Principles
2-2. Operation of Control Parts
2-17 CL-S700/CL-S703/CL-S700R
(3) Operation panel
This is a panel used to indicate the operating status of the printer and to set specifications. It
consists of 4 keys, 6 LEDs and 1 LCD.
(4) Thermal print head
The thermal print head has the following thermal elements. It also has the print head driver
circuit.
• 864 dots (CL-S700/CL-S700R)
• 1275 dots (CL-S703)
(5) Sensors
CL-S700/CL-S703/CL-S700R (Printer Part):
The following 9 sensors are used:
Sensor name Description
Top Cover Open Sensor It is a photo interrupter to detect top cover open. (“SA,
Cover Open Sens”)
Head Up Sensor It is a mechanical switch (“SA, Head Up SW”) to
detect head open/close status.
Each transparent sensor:
Consists of 1 LED.
Adjustable Sensor and Front Fixed
Sensor
(Consists of the transparent sensor
and reflective sensor.)
Each reflective sensor:
Consists of 1 LED and 1 phototransistor.
Thermal Head Temp. Sensor A thermistor incorporated in the print head.
PF Motor Temp. Sensor A thermistor attached to the PF Motor.
Ribbon Encoder (Ribbon Running
Sensor/Ribbon End Sensor)
A photo interrupter to detect ribbon running. It also
detects the ribbon end. (A part of the “Unit, Frame
Ribbon L”.)
CL-S700R (Rewinder Part):
The following 5 sensors are used:
Sensor name Description
Peel Sensor It is a photo reflector to detect the presence of peeled
label at the exit of the printer.
Rewinder Cover Open Sensor It is a mechanical switch to detect rewinder cover
open/close status. (SA, Interlock SW)
Form Sensor Two photo interrupters that are used to detect the
amount of liner wounded by the flange. Full state is
also detected. (PS501 and PS502 on the “SA,
Rewinder PCB”.)
Encode Sensor A photo interrupter to detect the running of rewinder
motor. (A part of the “SA, Rewinder Motor”)
Rewinder Motor Temp. Sensor A thermistor attached to the rewinder motor.
(A part of the “SA, Rewinder Motor”)
