    "scanner bulb warming up" is the error message and the cancel button light flash. when I unplug the unit for 30 seconds and plug it back in I get the same message

  • slharrell Dec 11, 2009

    Yes I power cycled the 3330 and the scanner is lit up

  • larry_d44ca May 11, 2010

    Exact error message is? Does unplugging the unit for 30 seconds then plugging it back in and having it cycle through all of its startup procedures help?

    Have you power cycled the 3330? If you lift the door on the flat bed is the scanner lit up?

Apparently this is a very common issue with this printer. Some repair people won't touch it and tell you to buy a new printer. However, I have been able to find a solution to your problem. You need to clean the scanner mirrors and the black ribbon under the cover.

*****CAUTION***** This is a very complicated project and can result in the loss of your printer. So proceed VERY cautiously, or send it in for repair.

Below are some instructions I have found to disassemble your printer. Please remember, only do this at your own risk and use extreme caution while doing so.

Here are the instructions:
Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} HP LaserJet 3330 Scanner Unit Disassembly Procedure

This is not an Hewlett Packard document, the author does not work for Hewlett Packard and is not responsible for any damage you do to your printer. This procedure is for skilled repair technicians and is not recommended without some knowledge of equipment repair. Proceed at your own risk.

  1. Open the document feeder and pull up on the two black tabs on the left and right.
  2. Pull up on the right part of the doc feeder then the left, remove doc feeder, set aside.
  3. Open front door and rear fuser door.
  4. Remove screws closest to teal colored fuser release levers. (side cover screws)
  5. Pull right cover out from back while releasing clip on bottom of cover, pull cover towards the back and remove.
  6. Push on indentation at back of left cover and pull out at back, this cover is hinged.
  7. Remove four screws now visible at base of scanner assy., two on left two on right.
  8. Slide covers towards back and remove.
  9. Remove two screws in the back just above the fuser and just below the scanner assy. base. Remove two screws in the front, visible now after removing the scanner assy. base covers on the right and left (the left one is just behind the hinged cover near the top hinge.)
  10. Remove flat ribbon cable (on left side) at either connection point to disconnect scanner assy. from print engine.
  11. Entire scanner assembly can now be slid forward and removed.
  12. Close the front, rear and left side doors on the print engine portion and set it aside.
  13. Grab front panel face plate at top and pull forward and remove. (or pry gently at top of face plate).
  14. At top of exposed front panel you will see four slots in the scanner assy. At the third one from the left there is a latch (dark grey plastic). Push down on the latch with a screwdriver and slide the whole panel assy. to the right. Lift up and out making sure to disconnect the cable.
  15. Remove the three screws in the now exposed dark grey front panel cradle and cover, remove the two cables connecting the cover to the main board, pry gently at the top outer corners of the cover and pull it forward and down, remove the cover.
  16. Now remove the four scanner assy. screws (one and the center front, center back, center right, center left) all are facing down under the assy. (Or just flip it upside down and remove the four visible screws.
  17. Turn the unit back upright and remove the four screws at the back/top (two of them are down inside where the doc feeder normally goes.) Remove the top scanner cover position. Note: When putting the top cover back on double check to make sure the scanner belt is not twisted.
  18. DANGER your about to work on the scanner carriage itself there is a really good chance that you could break it or the mirrors or bulb so proceed at your own risk.
  19. At the top and bottom left side of the black cover enclosing the mirrors are two slots, if you put a small screwdriver in the slots and push gently to the right and lift that side of the cover it should come loose. Then open it to the right and remove it from the right slots.
  20. Remove the black screw at the front of the assy., Disconnect the white wires from the CCD board and out of the harness, lift the clear plastic bulb holder out with the bulb then remove it from the rear. (it’s a tight fit at the front.)
  21. The top mirror is held in by some really tight clips they have to be removed from the bottom right (clean the mirrors without this step if possible). NOTE: optical mirrors are not like a bathroom mirror, there is no glass covering the reflective surface. The back side of the mirror has glass covering it so if you get it in backwards it won’t work. (The way to tell which side you have is touch your screwdriver to the mirror and if it’s the right side the screwdriver will appear to touch the reflection of the screwdriver, if it’s the wrong side the screwdriver will not touch the reflection of the screwdriver because of the glass covering the reflective surface.
  22. Now clean the remaining mirrors and lens very thoroughly with alcohol. Make sure they are very clean. You can put the top mirror back and clean it in place to make cleaning it easier.
  23. When re-assembling the top cover check to make sure the white strip on the right side is clean.
  24. Reverse procedure for re-assembly.

SOURCE: not working properly

I'm having a similar problem. So far my solution has been to disconnect the 3330 from power for a longer period (> 30min.) and then switch it back on again. After the self-test everything appears to be ok again. I've got no idea why, but this seems to work (for now)

Scanner Error - Power On Power Off


Hello,

The "scanner warming up" error is usually caused by dirty glass or mirrors in the scanner assembly. Here is a link to a step by step guide that tells how to open the scanner unit and clean the optics to clear the error.

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.

Will not print. Message says


Your scanner bulb is not warming up. It would cost more to repair it than buying a new printer.

If you scanner error 5 or printer hangs at scanner bulb warming up than the issue is with Scanning Assembly inside the printer and it is hardware issue.

Scanner bulb warm up


I have the same problem and it seems that the only way to fix this is to replace the scanner bulb. The problem is that, as far as I can tell, the bulb comes as part of the scanner assembly - and so you have to replace the whole scanner assembly. It is quite expensive - 200 to 300 dollars Canadian. There are whole machines available for $300.00 though so is it worth repairing if one cannot just buy the bulb? Ger.

Scanner error 6


Scanner errors are as follows for that model:

Scanner error # 

1 = dark find
2 = LMW temp find
3 = bulb warm up from off
4 = bulb warm up from coarse
5 = cal label find
6 = doc original find
7 = LMW final find
8 = cal label find after scan
9 = cal label find prior to standby
10 = doc original find prior to standby
11 = bulb warm up from standby

I would see if there is an original on the flatbed glass (platen), or if something is obstructing the scanner view.

If the error persists, replace the scanner
assembly or the formatter pcb

Scanner not working - get error message


First, check to see if the bulb lights up, if not you have bad bulb. the bulb can be ordered separately. if the bulb is good, you have a problem with the main board.
