2-1-9. Slider PCB
The slider PCB is located on the inner side of the head cover. It relays the head control signal
and head driving signal from the HDC PCB to the print heads. It contains the sensor circuit
which detects the signal from the thermistor on each head and the signal from the paper-
width sensor.
The slider PCB is connected to the HDC PCB with 7 main FPC cables and connected to the
heads with 12 head FPC cables. In addition, the slider PCB is connected respectively to the
linear encoder that detects the ink discharging position with the linear scale, to the paper
width sensor PCB and to the cutter solenoid.
