I have an HP7000. First problem was no paper pickup. I put the printer away for a while and now the printer powers up with a solid green light. The printhead will move back and forth if I lift the lid and the roller above the paper output tray will continually move momentarily every 15 seconds. The printer is recognized, has the correct drivers, print jobs are sent to the spooler but nothing is happening. Hany help would be appreciated.
