1. Outline

The machine’s printer control system is the brain of the printer unit, executing various printing operations in response to commands from the main controller.
Printing operation is under the control of the DC controller; when a print command arrives from the main controller, the DC controller drives the motors and solenoids as well as high-voltage loads to form images on paper as dictated by video signals.
The printer control system also serves to convert AC power from an outside source into DC power for supply to various loads.
The following is a block diagram of the printer control system:

　

2. Compatibility

There are 2 types of DC controller PCBs to suit the iR2270/2870 Series and the iR3570/4570 Series, and there is no compatibility between these DC controller PCBs.

　　　　　

3. Specifications of the Printer Control System

The printer control system is based on the following specifications:
