We have been told that the motor could "possibly" be bad, but the technician working on it says they won't know for sure until they replace it. I used to work on printers quite a bit, and I know that if you know what the coil resistance is supposed to be (+/- tolerances) you can test it with a volt meter to see if the coils are bad or not. The technician cannot locate the coil resistance information and supposedly, HP does not supply this information in the service manual for the Designjet 110 series. Does anyone know if this information is available? If so, what are the coil resistances?
