The power supply system and the signal lines are shown below.
The power supply unit supplies DC +5 V and DC +24 V to the main board. It also supply an AC voltage to the heater
lamp.
The controller receives a compressed print data from the host PC through an interface.
In the parallel interface, the printer status is returned to the host PC in the IEEE1284 nibble mode.
The controller adjusts the size and position of the print data to generate image data.
The image data is sent to the print head unit via the main board for printing.
The main board controls the various parts of the engine including the paper take-up section, charging section, develop-
ment section, transfer section, fusing section, and paper exit section.
