Hi Ron,

We have talked long time ago about a remote control repair. I need your help on this one.

This is not a TV but electronic circuit questions.

I have a Panasonic Multifunction laser printer model KX FLB751 that gone bad. Whenever I turn on the power I get an error with beep and showing "Service 1" on its LCD display. So, I bought the service manual and posting the relevant pages here.

In this flow chart, the second step to the right it says, "Is the clock input into CN612 - 1 pin? "
What does it mean?

Is CN612-3 pin "L"?
What does it mean? Would you explain to me?

See here the flow chart:


Here is the corresponding circuit diagram for the Polygon motor.

Have you tried the Panasonic product support site for this printer? SIMPLE, type in your question and you get an answer from someone who knows the product.
