When the all-in-one is connected to a grounded power source and is turned on, the control panel shows Hewlett Packard with moving cursors indicating that the firmware code is loading, and the main motor rotates for approximately 45 to 60 seconds. When the firmware is done loading, Scanner bulb warming up might appear on the control-panel display, and the scan head moves back and forth for 10-15 seconds. If you lift the scanner lid, you will see that the scanner bulb is lit. Near the end of this time, the automatic document feeder (ADF) motor turns on for about two seconds. No power due to failed power source, cable, switch, or fuse. Motor does not rotate. ADF motor does not rotate. Scanner bulb does not light. Does Ready appear in the all-in-one control panel?
