Check for continuity across the terminals to inspect each component of the operation unit
PCB keyboards.
Precautions:
• Before starting a continuity check, always turn the copier main switch off, disconnect
the power plug from the wall outlet and detach the operation unit PCB from the copier.
• The positive probe should be connected to the terminals in the first column and the
negative probe to the terminals in the second column. There should be no reverse
continuity.
