2.4.5 Motor Driver

2.4.5.1 Media take-up PCB components

iPF810
a) Driver IC (IC104)
Media take-up motor drive function
This function controls the Media take-up motor based on the control signals from the main controller.
Sensor relay function
This function relays the input signals from the Media take-up paper detection sensor and Media take-up on/off sensor to the main controller PCB.

2.4.5.2 Lower roll unit PCB components

iPF820
a) Driver IC (IC2)
The lower roll media pick-up motor is controlled on the basis of a control signal generated from the main controller PCB.
b) Clutch/solenoid control function
The clutch and solenoid are controlled on the basis of a control signal generated from the main controller PCB.
c) Sensor relay function
The sensor relay function transfers input signals from the sensors and switches to the main controller PCB.

2.4.6 Maintenance Cartridge Relay PCB

2.4.6.1 Maintenance cartridge relay PCB components

iPF810 / iPF820
a) EEPROM (IC1)
The 128-KB EEPROM stores all information written in the EEPROM on the main controller PCB.
