Scanner bulb warming up

When I start the machine it constantly says scanner bulb warming up and the bulb moves back and forth one centimeter. It used to do this less frequently but now it won't stop.

Can you shed any insight what may be going on and how to fix it?

    My printer just says bulb warming up, but the bulb doesn't move. I'm thinking the bulb is just going out. Is it hard to replace?

    Mine is doing the SAME thing and then it makes this grinding sound. These are the crappiest printers I have ever seen. I have had it under warranty and they have had to send replacement parts twice and finally replaced with a refurbished unit, which now is doing the same thing.....FRUSTRATED I will never buy this brand of printer again.

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.

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.

Does the scanner head try to move? Look at it closely when you power it on. Look at the belt that pulls the scanner back and forth - is it broken?

Hello,

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.

Hp 3055 no lingt on the control pannel, no power up, no warm up, it just like pluck off machine. nothing comes on.. what is the problem? anyone experience it? please give me a hand... thanks


Hi benkoh76: Here is your problem. Troubleshooting checklist Follow these steps when trying to solve a problem with the all-in-one. Step number Verification step Possible problems Solutions 1 Is the power on? When the all-in-one is connected to a grounded power source and is turned on, the control panel shows Hewlett-Packard with moving cursors indicating that the firmware code is loading, and the main motor rotates for approximately 45 to 60 seconds. When the firmware is done loading, Scanner bulb warming up might appear on the control-panel display, and the scan head moves back and forth for 10 to 15 seconds. If you lift the scanner cover, you will see that the scanner bulb is lit. Near the end of this time, the ADF motor turns on for about two seconds. No power as a result of a failed power source, cable, switch, or fuse. 1. Verify that the all-in-one is plugged in. 2. Verify that the power cable is functional and that the power switch is on. 3. Check the power source by plugging the all-in-one directly into the wall or into a different outlet. Motor does not start. 1. Verify that the all-in-one is plugged into a working electrical receptacle. 2. Verify that the print cartridge is installed correctly. Follow the instructions on the control panel to remove and replace the cartridge. 3. Verify that the top cover is closed. ADF motor does not start. Open the ADF cover and remove any orange shipping tape inside the ADF. Verify that the ADF connector is connected correctly to the scanner. If the ADF motor still does not rotate, replace the ADF. Scanner bulb does not light. If the scanner bulb does not light, verify that the wire-harness connectors from the scanner to the formatter are connected correctly. If the error persists, replace the following components one at a time until the problem is resolved: scanner assembly, formatter. Hope this helps

How Do Stop Scanner Bulb From Warming Up?


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.

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.

Scan head/carriage not parking in one spot -- keeps moving.


The scanner is having trouble getting its "white reference" usually due to dusty mirrors, but can also be the bulb losing brightness. These are not a easy machine to pull apart if your not used to it.

Good colour laser MFP, depends on volume of prints and remember colour dont come cheap, but dont use refill cartridges, Kyocera and Oki both have good Models

Hi, when you lift the cover where the flatbed glass is can you see the scanner trying to move back and forth? Also you might want to check and make sure the scanner lock didn't get moved to where the scanner just goes back in forth ? Are you getting any error codes?
