Scanner bulb stuck on left after mirror cleaning, machine frozen

Every year or so I get the loud ratchet sound, so I do the mirror cleaning by moving the bulb all the way to the left (let the machine move it by turning it on and off about 20 times, instead of me forcing the belt), then opening the small pane of glass and cleaning the mirror. Done it at least 7 or 8 times now, and it always solved the problem.

Now I've just done it again, and the bulb is stuck on the left. it won't move at all toward its normal position on the right. After about 60 seconds I get the "scanner error" message.

What can I do? The machine is frozen and I can't access menus or do anything with it.

    Well, I wasn't sure what you meant by "locked", but it prompted me to browse the menu settings and finally to reset all settings to default. For some reason that did the trick.

The scanner is locked. You need to see the user manual and look for the scanner lock. It just needs to be switched to unlock.

Hello, The scanner & photocopier were not working and the screen was just stuck on the "scanner bulb warming up". Then, after days of trouble shooting, it finally began making a noise,...


From what you described it sounds like you need to get the "scanner assembly" replaced.
The bulb is probably bad and won't come on to full power.
Not knowing what kind of printer you have, probably won't change the fix. If you can look at the event log you may be able to see an error code which could make it a definite scanner assembly replacement.
If you want to throw money at this unknown printer, get a tech to look at it and give you an estimate.

Scanner errors on HP 3330, 3380 and other 33XX Printer/Scannners

1. Turn off printer and unplug power.


2. Lift up scanner lid so that you can see the scanning glass


3. Locate the screw on the top left side next to the small window of glass. (1 in picture) This glass is the section used for scanning from the automatic document feeder. Remove that screw and then the plastic that it was holding. Lift the glass out.

4. With the glass removed you can see the drive belt for the scanner. You need to rotate it until the scanner head moves to the left far enough that you can see the top of the moving part of the scanner. You will see a thin light bulb and a slot. Do not touch the lightbulb, it is fragile. You may need to pull on the assembly to move it the last bit to access the slot


5. Use a flashlight to see down into the slot, you will see a thin mirror that runs the width of the slot. If that mirror is dirty, that may be the problem and it needs to be cleaned.


6. Use a q-tip moistened with either alcohol or window cleaner to gently clean the mirror. Make sure you do not leave any lint in there.


7. Replace the glass and turn printer back on. If this is going to work it should come to ready.

The Scanner bulb warming up cycle is stuck and it keeps making the set-up sound. how do you stop it?


This worked for me today 8/29/10

A much easier way to clean the mirror.
Thanks to: http://www.statusq.org/archives/2008/01/21/1745/

Basically, you power off the printer and unscrew the screw which allows you to remove the small piece of glass to the left of the main scanning glass.

Using some needle-nosed pliers through the opening, grasp the drive belt and use it to move the scanning head across from the right hand side of the scanning area to the left, until it is right under the opening. At the bottom of the wide slot, there is a mirror, and it gets fogged up with something.

Shine a good light in there and use dry Q-tips to give the mirror a good clean. Then reassemble everything and turn the printer back on. After a little warm-up, you should get the Ready€™ prompt again, and your heart will be filled with joy.

The whole process should only take about 5 mins. There may be other things which cause a scanner error, but this fixed it for me and, it would appear, for many others.

Scanner error 5


Try this one open up the scanning lid, use a small allen wrench and pull the screw at the left side of the frame that holds a 1 inch wide by 12 inch long piece of glass. pot ur finger inside the housing and begin to roll the gear/rubber belt to move the scanner bulb assembly towards the left side as far as you can go. Then, turn the machine off and on.
If you are adept at printer repair, remove the right side cover, by removing the two screws in the hand hold area. pull the cover out at the bottom, using the handhold area, it will pop quite loudly. Once you get the cover off, you will find a large sheetmetal box with a row of connectors across the top of the circuit board. You do not need to remove the sheetmetal box to access the connector I am referring to. The four wire bundle I'm referring to has black, yellow, blue and red wires going to it. It's pretty much in the center of the row of connectors Be sure it is secure.
If the connector is securely inserted and no pinched wires are observed, the next most likely cause for this issue is a calibration stip for the scanner head inside of the scanner top. There are no spare parts for that level of repair. Opening the scanner top to repair it is likely to let in dust or debris and you won't find much that can be done if the calibration strip has moved or delaminated. The scanner top will need to be replaced. I believe the part number for the scanner top is Q3948-60191 unless it's been replaced with a newer part number.


that shud work if it doest contact hp....

I have a HP Laserjet 3330 prints just fine but won't copy. It lights up will start to scan then stay on one side and lock up. I took it to a repair man he said that the ratchet is broke. What does that...


Ok, The scanners on these things rely on "seeing" if you will, the end of there travel across the glass. If they can't "see" where they are supposed to stop they try to keep going, reaching the end and causing the noise you describe. The noise is the toothed belt slipping on the pulley that drives it. There is no Ratchet.

Try this:
Should be two pieces of glass the big one and a smaller strip to the left.
Remove the strip I'm pretty sure it is one screw and a latch that slides to one side to remove.
Clean the glass.
Get the scanner assm. over to the opening. pretend to copy or by hand with power off.
Gently wipe the scanner bulbs and use a Qtip to clean the mirrors below as best you can.
At the end of the scanner assm. (Front of Machine) you will see a piece of glass kind of pointing at you. It looks like it shouldn't be there. Clean this it is the "EYEBALL"
this has worked for me.
Hope it Helps

Loud ratchet noise


Have you been using ink cartridges other than store bought? Reason I'm asking is that i used a refill kit, and tried those half price refill places, only to find ink was leaking out when not in use & clogged up the ends where the cartridge moves across. take a flashlight & look at the ends of the track that the cartridges slide across on, you may see a build up of ink, that won't allow the cartridge to travel as far as it needs to go to run properly.

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 error 5


It's a problem with the scanner unable to "see" its home sensor. The home sensor is a black & white film strip stuck onto the flatbed glass, just above where the scanner head homes. The printer needs to "see" the two little black 1mm square bumps in the white area. When the scanner head "homes", as it just disappears under the plastic it should move left and right as it looks at the home strip. If it keeps going and chatters at the right-stop it didn't see the home strip.

This can be caused by dirty mirrors, or lens in the scanner head (clean them);
Low or off color light (replace the bulb or high voltage power board on bottom of scanner head);
Broken, cracked, or loose scanner head ribbon cable (replace or repair);
Dirty or crooked home sensor film strip (I had one of these: the black & white film strip stuck to the flatbed glass was slightly crooked, it doesn't take much!)
Dirty slide bar (clean & oil);
Bad stepper motor, bad scanner PCBA (replace).

Remove the small glass pane of the left side of the scanner bed. You onlt need to remove one screw. Push the driver belt which will move the scanner to the left. It can be a little tricky to move the scanner the last little bit so you may need needle nose pliers or someone with a hook (I used a fork) to pull the scanner last little bit. Once the scanner is in the open spot where you removed the glass panel, simple take a q-tip and clean the mirror.

I did this and my machine is working just fine.

Coppier Problem


The trouble is that the scanner assembly can't find its "home" station. Here is the most common solution. There is a reflective white stipe under the scanner glass that the scanner looks for. If the stripe is dirty, or if the scanner mirrors are dirty, the scanner won't sense its location, and cause a "scanner error". A qualified technician should be able to clean the assembly. The other option is to replace the scanner assembly. I hope this helps.
