I have an HP T2600 that throws a 1009-0001-0001 error when booting up or trying to scan. Service manual says to block the sensors in scanner to turn on feed motor. Motor doesn't run when doing this. When I preform a 010901 motor doesn't run and test fails. I have replaced motor along with the sensor and harness and the scanner PWB. Nothing has got me past where I started. HP tech support had me reseat USB harness with no luck. This is a billable machine so I don't want to be shotgunning parts. Any suggestions out there?
