Servicing Laserjet 6p in difficult circumstances

[EamonX1]

I am not in a country where HP engineers are available, but I have a basic knowlege of electronics, have built radios etc. When I switch on my printer (HP Laserjet 6p - model number C3980A) it does not power up, and it displays a fixed amber led light.(nothing else). Using the Service Manual for this model, I have successfully removed the Formatter PCA, the Fusing Assemblies and the DC Controller Assembly board. Checking the connector socket on which the motor assembly rests (J601), using a volt/resistence-meter, I cannot locate any current - there is no power reaching the motor. The main fuse fh101 is not blown. What else should I check?

More than likely, the fuser is bad. Not getting a complete voltage loop.
Make sure the sensor flag at the top is in place when you put the main board back in.

i agree with michael its def the fuser assembly if nothing else works just bomb it.
