4036-501 Scanner Control The scanner system card provides the logic and information processing that is necessary for the scanner to function. Every electrical component within the scanner is connected to the scanner system card. Sensors in the scanner send status information to the system card. The system card processes that information, shares it with the MFD controller cage, and compares it to timing tables stored in ROM. Acting on the results of the processing, the system card sends commands to the various scanner components; switching on/off the motor and exposure lamp. 1-24 Service Manual

the scanner system card. Sensors in the scanner send status information to the system
card. The system card processes that information, shares it with the MFD controller cage,
and compares it to timing tables stored in ROM. Acting on the results of the processing,
the system card sends commands to the various scanner components; switching on/off
the motor and exposure lamp.
