a) Latch ICs (IC401)
DI sensor reading control function
This function obtains the DI sensor value in the printhead and head rank for each color and sends it to the main controller PCB based on the control signals from
the main controller.
Environmental temperature reading control
This function sends the environmental temperature detected by the thermistor on the board based t the main controller PCB based on the control signals from the
main controller PCB.
Image data relay function
This function relays the image data from the main controller PCB to the printhead.
The function for processing image data is not supported.
b) Multi sensor control ICs (IC503 and IC504)
These ICs are used to generate the multi sensor LED control signal and adjust the gain.
