Question about HP LaserJet 3330 All-In-One Printer
The 'scanner warming up' error is caused by dirty scanner optics. What happens is the scanner initializes the lamp and starts reading the scanner pickup waiting for the light to get to a certain brightness level. When the optics get dirty from dust or smoke then the light getting to the scanner pickup is reduced so the unit thinks the scanner bulb has not reached the correct brightness so it says wait. What you will need to do is dis-assemble the top portion and clean the scanner optics. We have a step by step guide to do this procedure posted on our web site at: http://www.ccl-la.com/blog/index.php/hp-laserjet-3330-scanner-warming-up-error/ This should get you back going again.
I hope this helps you out, if so please rate our solution.

Warning or warming?
A scanner lamp warning means no scanner lamp. Unit needs service. No user safely serviceable parts
