Laserjet 6L This printer shows all 3 lights, and won't run. If I press the front-panel button, the middle light goes out (I read somewhere that this indicates a fuser problem; can anyone confirm this?) When the printer is first powered on, the scanner motor runs up and then stops. Very occasionally, the transport motor also runs, and the printer goes to the ready state. However, if I then press the button for a test-print, after the data has been prepared, the scanner motor runs briefly, (and sometimes the transport, too); but then I get the three-lights error. I have measured the resistance of the fuser element, and I get about 105 ohms (the manual says it should be 30 ohms). There appears to be 12V AC across the element, which doesn't seem to be anywhere enough to me. Would someone kindly enlighten me as whether the fuser is the real cause, or whether it could be a power-supply problem? Thank you.

Check the thermistor that measures whethter the fuser is getting hot enough. May have crud built up on it or defective. I concur with dodgecharger that the fuser is the problem. As long as your going to have it apart, invest in a separation/feed assembly kit. I'm sure you're having problems with mulitple paper feed problems by now. It's still a tank of printer. Always liked them. Hope it helps Ed

The way-off ohms reading would suggest the fuser element is bad. If the fuser is not heating, a sensor will tell the logic circuitry so, and thus your error, and no-print condition. I'm reasonably certain the self check at power on checks for fuser heating. Guessing here, but a heating check is likely done prior to a printjob being completed too. If you can check the voltage at the fuser during the self check or as it readys to print, this would tell you if full voltage is applied. The 12 volts you are seeing probably is a standby voltage. The HP laserjets I've worked with all have higher heating voltages than this. You might be able to find some more accurate info elsewhere on the 'net.
