Question about HP LaserJet 3330 All-In-One Printer
The printer is fine until I scan a document. Then I get a message that the scanner bulb is warming up and the scan bar keeps going back and forth. I cannot stop it and no can no longer print. Any solutions? Thank you.
There are 3 possible causes to this problem.
First dirty scanner optics this causes scanner to unable to get to the home position. This step should be done first. You will need to remove the ADF assy, left, right covers, remove control panel, remove control panel base cover, remove 8 screws 4 on top and 4 under scanner assy ( One screw on each side of scannerie front, left, right, back) Then carefully remove the glass. You should now be able to see the scanner assy, you will need a small flat screwdriver to disengage the tabs holding the scanner cover in place. Clean all mirrors with DRY q-tip. Reassemble and test.
2nd After cleaning scanner optics still doesn't resolve problem next step is to replace scanner formatter. You will need to open left cover, and remove the 2 screws and remove the smaller left cover. The scanner formatter can now be seen.
If above steps do not resolve problem, replace the scanner assy.
