Carriage Relay Pcb; Carriage Pcb Components; Motor Driver; Cutter Driver Pcb Components - Canon imagePROGRAF iPF5000 Series Service Manual

MEMO:
After replacement of the main controller PCB, the printer must be started up in the service mode to take over the setting and adjustment values to the new PCB
properly (the service mode will be switched to the PCB replacement mode automatically).

2.4.3 Carriage Relay PCB

2.4.3.1 Carriage PCB components

a) Latch ICs (IC1 and IC3)
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 (IC6 and IC7)
These ICs are used to generate the multi sensor LED control signal and adjust the gain.

2.4.4 Motor Driver

2.4.4.1 Cutter driver PCB components

a) Driver IC (IC1)
Cutter motor drive function
This function controls the cutter motor based on the control signals from the main controller.
Sensor relay function
This function relays the input signals from the cutter lift sensor, cutter HP sensor, and cutter right position sensor to the main controller PCB.
