- Service mode: After SERVICE MODE > ADJUST > GAP CALIB. has been carried out, pass paper to make
sure that it is detected properly.
- In executing Calibration concurrently with the main menu choice Auto Head Adj. or Manual Head Adj., Auto
Head Adj. or Manual Head Adj. first for the sake of higher color calibration accuracy.
Linear encoder sensor
When the carriage modes, the linear encoder sensor located at the rear of the carriage reads the slits on the linear
encoder to detect the carriage position.
Lift cam sensor
This is a photo-interrupter-type sensor. The lift motor is driven by a predetermined number of pulses received
after blocking of the sensor light by the flag, thus controlling the heights of the head and platen.
Environmental temperature sensor
The environmental temperature sensor installed on the carriage PCB detects the temperature around the
carriage.
The resistance of the thermistor that changes with the temperature inside the printer is reported to the main
controller via the carriage PCB.
The environmental temperature is used to calibrate the head sensor and to detect abnormal head temperatures.
Head temperature sensor
The diode-type head temperature sensors installed at the top and bottom of the printhead nozzle unit are used to
detect the head temperature.
The diode voltage that changes with the nozzle unit temperature is reported to the main controller via the
carriage PCB.
The detected head temperature is used to control the head operation and to detect abnormal head temperatures.
Printhead contact detection
The printhead contact status is detected by testing the electrical conductivity.
It is detected according to the voltage changes at the two terminals of the contact faces, power supply terminals,
and GND terminal.
