what else to check for 50 Service Error

on a Laserjet III, what else is there to check besides the AC power supply and the fuser (both good, they work in the other printer) and how can I check it (voltages, etc)?
Check our troubleshooting section tweaking page. You want to do the connector marked fuser.

ok, i tried that, no luck. Could the DC power supply be bad?
