HP Laser Jet 3300 Scanner bulb warming up non-stop (1619 Views)

Printer is continually in the "Scanner bulb warming up" cycle when plugged in. This means that the scanner is going back and forth non-stop in a tight area of the far right hand side of the glass plate area -- traveling a distance of maybe 3/4 of an inch -- with the light on -- continuously. It will not print from the glass plate, but it prints no problem from jobs sent from the PC.

There is a solution that works most times and I will post it one more time. Turn the printer off. Open the ADF and on the left side of the unit there is a small strip of glass held in place by a thin plastic cover and one screw. Remove the screw and remove the plastic cover and remove the glass. Now look at the back of the opening and you will see the belt that drives the scanner unit. Use a needle nose pliers to move the belt a little at a time to move the scanner unit from the right to the left. When the unit is almost over the opening use you fingernail to move it the rest of the way over the opening. Now get yourself a dry q tip and look down at the scanner unit and you will see a mirror. It may look clean but it has a fine film over it and use the q tip to clean the complete mirror strip. When done move the scanner back to the right using first you finger and then the pliers and the belt. When the unit is all the way to the right, turn the unit back on and see if it comes to ready. Most times it does and if that is the case open the adf cover and put the glass and cover back on. If you still get the error, turn the power off and do the procedure one more time and then see if it works. I have had a 95% success rate on this series.
