Check that the long light bulb turns on...try bypassing the "door open" switches to do this.

I keep getting a "Scanner Failure" error message every time I try to make a copy. I have tried all the trouble shooting the HP manual suggests but still no luck. Anyone know how to get rid of this...

This series of HP all-in-one units have a common problem that, over time, the exposure lamp. which is florescent, goes dim. The scanner looks for the right amount of light, and if it doesn't see it, it gives you the scanner failure. In some rare cases, you can dismantle and clean the mirrors and lens in the scanner, but most of the time it doesn't work.
There are no parts available for this unit.

HP Laserjet 3330 Multifunction monochrome printer,copier,scan and fax. This machine will warm up, and after it reads "scanner lamp warming", the scanner lite lights up, the carriage moves back and forth,...


This type of problem is usually caused by dirty mirrors in the scanner. After a few years of use the mirrors and lenses in the unit will get a fine coating of dust particles on them. The dust interferes with the scanner initializing the optics. When this happens the unit displays the Scanner warming up message on the screen and keeps trying to move the scanner assembly to get a good reading from the pickup. To solve the problem you will need to disassemble the scanner portion and clean all of the mirrors with window cleaner and a soft cloth or q-tip. To get dis-assembly guides just do a google search for the 'scanner warming up' error.

I hope this helps, If so please rate our solution.

51.20 error message on HP laserjet 4250n printer

It is an error with the laser scanner unit
1 Press ( SELECT button) to continue.
2 Turn the printer off and then on.
3 Reseat the connectors between the
laser/scanner and dc controller
PCA (J83 and J84).
4 Replace the laser/scanner assembly.
See Laser/scanner assembly.
5 Replace the dc controller PCA. See
Dc controller PCA.

If nothing from above works and the printer is no longer in warranty, it is possible if the printer is being used in a very dirty or dusty enviornment that the lens and optics of the laser/scanner are so full of debris that the beam detect error occurs. You can remove the top cover and the big black box in the center is the laser scanner assembly. Remove the screws securing the top cover of the laser scanner and remove and clean up all the optics to include the main mirror in the front. I usually use a damp q tip and for the mirror I slide up from toner cartrdige shutter area and observe from the top as it cleans the mirror. Removing the complete assembly on this model is not easy since there are a couple of cables going to the dc controller which are difficult to remove so removing the top of the assembly is easier.
Here is the service manual:

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.

Scanner error message hp laserjet 3030

This problem has to do with the scanner mirror. You may hear a grinding sound, also. The reason it does this is because the scanner bulb cannot find 'home', so it keeps trying to find it. Well, it uses the mirrors to reflect on another object inside the scanner to tell it when to stop. The mirror on top of the right next to the scanner bulb may need to be cleaned. This works every time for me, except the same problem always comes back sooner or later.
how to clean-
1.unplug your scanner
2.notice the glass covering on the left side, it can be removed with a Phillips screwdriver. Unscrew the plastic surrounding the glass and then remove the glass covering.
3.Plug the scanner back in and wait for the scanner to move left and then unplug it before it starts moving to the right. Repeat this until scanner bulb is all the way on the left of the machine.
-an alternative method-
with the glass covering removed, use a pair of pliers to move the small belt that moves the scanner bulb. keep moving it until the scanner bulb is all the way on the left of the machine.
4.With the scanner bulb assembly in reach, grab a Q-tip and gently clean the mirror that is just to the right of the bulb. You might want a flashlight to see the dirt and dust.
5. Put the glass covering back on.
6. Plug in the scanner.
At first to me it seemed like it wouldn't work, but it does.
Hope it helps. Reply back if it does.

Scanner failure

I have been finding that scanner failure when the light is still working is usually a dirty scanner. Disasemble and clean the mirrors with windex. No job for a novice, but what have you got to lose at this point.
