Default Tutorial/schematics of Printers/Copiers

Dear Technicians,

Printers and Photocopiers are used by print centers and offices every day. They have to repair/service these devices 2-4 times a year. I heard from a print center owner that the repairman asks a lot of money every time he services their devices.
In general, a printer/copier contains the following main parts:
1- A power board
2- A controller board
3- A number of motors
4- A number of sensors
5- Ink, Cartridge, Ribbon, and so on
6- Body case, paper containers, and covers
7- A few IO ports for communication
8- Fax/scan parts
9- A Keyboard
10- A small display

There is a service manual for every printer/copier that explains most of these parts except for the controller board.
Is there any tutorial on how a controller board works and what components it contains?
Can schematics of controller board be found for any printer/copier?

thanks
