Controller Pcb (Including Recording Data Generating Pcb) - Riso ComColor X1 series Technical Manual

2-3. Controller PCB (including Recording data Generating PCB)

2-3-1. Role of Board
Main roles of the controller PCB are as follows.
• Functions to generate image data.
• Converts data supplied from a computer, scanner, or USB memory to image data and transfers it to the
recording data generating PCB.
• Job management functions.
• Manages jobs (print jobs from a computer or image data from a scanner).
• Functions for transfer of image data.
• Transfers expanded image data to the image processing PCB, based on job information.
• Functions for controlling the operation panel unit.
• Controls the operation panel unit.
• Download functions.
• In this system, all downloads to units that require them are done as follows: An update program stored
on a USB memory device is read after the device is inserted in the USB port managed by the controller
PCB, and a downloading application stored in memory on the controller PCB is executed to download
the data to the controller PCB, engine control PCB, scanner, or fi nisher.
• System control functions.
• For overall control of the system as a whole.
• Scanner control functions.
• Controls scanners connected as optional equipment.
• User authentication functions.
• Controls user authentication (optional).
• Image adjustment (for details, refer to the chapter on image adjustment).
• Functions to back up setting values of the engine control PCB.
• The controller PCB unit backs up information to the hard disk, including mechanical settings values and
counter values saved by the engine control PCB.
