2. Theory of Operation
2.3.1.5 Jam detection
Jam
Document jam is detected by the sensors shown in the illustration. Check timing of the
document jam detection has already been memorized in the ROM of the image processor
circuit PCB beforehand so that jam occurrence can be judged from the information if a
document exits or not, at the corresponding sensor block.
When jam occurs, the connected equipment memorizes the contents of the jam as a jam
code. The jam code of the MFP can be checked by outputting the jam error history report by
the service mode of the connected equipment.
2.3.1.6 Power supply
Power supply
Overview of the power supply is shown in the illustration below The power supply block of the
MFP receives the power supply of two systems that are 24 V power supply and 3.3 V power
supply.
