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?

You may have to have the scanner replaced.

4690 MF Printer displays the following message:"SCANNER MOTION ERROR, CHECK SCANNER LOCK"


I would open up the scanner and check to see if it can move, When you turn on the machine does the scanner try to move before the code shows up.

Keeps jaming on the right every time


Follow this step to clear the jam

press the diamond shape button start button to eject the jammed paper. If the jammed paper is not ejected, go to the next step.
if the paper is stuck near the sheet feeder or output tray, gently pull it out.
If the paper is stuck inside Epson Stylus CX7800, press the power on button to turn it off. Open the scanner and remove any pepr inside including any torn pieces. Do not pu;; it backward beacuse this can damage the sheet feeder. Close the scanner, then turn the epson stylus CX78oo back on.

Error: power off power on


This is a typical problem with this printer also followed with scanner error. Most likely cause is scanner optics dirty causing the scan head to be unable to find home position ( white strip on the underside of the glass). Note cleaning the scanner optics requires technical know how as its fairly difficult to remove the glass. Damage to optics may cause image defects on output.

Scanner bulb stuck on left after mirror cleaning, machine frozen


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.

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.

Scanner light stays on


I have the same problem. I chatted with HP customer care for an hour but it can't be fixed. The only thing you can do now is set the power saver mode to 2 hours, so bulb will turn off in 2 hours. Only way to minimum power consume.

Scanner and coiper won't work printer does work


Hi Bbear,

The problem here is with the scanner bulb, the scanner bulb is bad.
I mean to say that your scanner bulb lit for a while and goes off.

This confirms that the scanner bulb is currupted.

I have a web link, which is given below with some of the troubleshooting steps to perform.

http://h10025.www1.hp.com/ewfrf/wc/document?docname=bpu01105&cc=us&lc=en&dlc=en&product=390315

Click on the web link given above and perform the steps.
If this fixes the issue, that would be great else you need to replace or get a new or refurbished printer.

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.
