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.
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.

It sounds very much as if the scanner is faulty/failed. The warming-up phase is to ensure that the scanner lamps output is steady, making for consistent scans. Usually this is just a simple timing circuit.
Having once tried to fix a broken flatbed scanner myself, I found that obtaining the correct replacement lamp for it was impossible - I think inkjet printers and scanners are considered "consumable". You may be better off buying a new printer. Alternatively, if it keeps producing good prints, consider buying a separate scanner. HTH
ISSUE: A Scanner Bulb Error message is received as a result of the HP LaserJet 3300mfp series product scanner's inability to find the home reference point. SOLUTION: Perform the following steps to walk the scan assembly from the home base and resolve the issue.
1. Remove and replace the power cord from the unit. 2. Wait approximately 35 seconds for the scanning assembly to "walk out" and then quickly remove the plug again. 3. Repeat steps 1 and 2, three to four times until the head moves approximately 1 inch away from its normal resting place. 4. Replace the plug and let the product fully finish the boot cycle.
If this does not resolve the issue or the issue returns, upgrading the product firmware may help. The firmware upgrade can be found at the HP Web site Downloads, Drivers, and Notifications page .
How does the bulb look? Is it bright or kind of dim. The bulb warming error is designed to halt use of the machine until the scanner bulb reaches the correct output level. As these are basically a flourescent tube, they will dim over time and at a certain point they will not generate enough light to enable proper scanning. If the bulb is dim, it will require replacement.
I found this solution at HP website. It worked for me. Good luck!

the cables connected internally to the scanner unit had gone short some where in between you have to check it manually by opening the device .and then remove the cables and replace them with a same length cable.you can get the cables from any electronic shop who keeps printer assessories.
