This looks like a hardware fault. I hope (by now) that you have got an RMA and had it replaced.

SOURCE: Scanned pictures has thin blue line running through it

I had the same problem with My Espon Perfection V500. I called tech support and they had me do the following sequence.

1. Turn off the unit
2. Unplug the lid from the base
3. Replug in the lid.
4. Turn the unit back on
5. Go into the Epson software in Professional mode, Configuration, Other and select Reset All
6. Rescan the picture.

It worked after that. Of course it also lost all my preset sizes in my Custom box and any other settings I had. I suspect the lid plug is what the problem was.

Another word to the wise. To test it I put in a picture that was laying on my desk and rescanned it and was disappointed to see the line in the result. A few minutes later I discovered that this particular line was in the original picture.

SOURCE: hp 7400c haze on INSIDE of scanner glass

I figured this one out.

There is a language panel on the front (that tells you what each button does). The original instructions mentioned putting the panel on but not taking it off. If you use a small, thin screwdriver or thin, dull knife from underneath, you can work your way across the bottom edge, popping off the language panel. When you remove the panel you reveal three screws, one rather tiny one in the center toward the bottom, and two medium sized ones to the sides closer to the top. Slide the glass cover up and off. There are two more medium sized screws near the slots for the cover. Remove all five screws. The assembly with the glass comes right off, allowing you to clean both sides.

The scanner glass inside is cloudy


I recommend you do not take off the glass. I have done it and was never able to get rid of the dust, which really shows up on every scan. The fogging has something to do with an optical coating on the underside of the glass. If I knew then what I know now, I would let it be. If the fogging doesn't show up in scans, leave it. If it really does show up, the glass itself is often held down by simple double stick tape. You try to keep the tape intact so you can put it back down. It may be strong enough that the plastic frame on top of it could snap. Do it in as clean (not dusty) environment as possible so dust does not drift down inside the scanner. Never touch the lamp or move the scan mechanism. Again, don't do it unless it's showing up on scan results. Sadly, nobody "fixes" scanners, they are disposable, like coffee pots, even if they cost 300.00.

Use of Scanner


On this model there is a SCAN in black and white or color buttons but you need to have something on the glass to scan. Once it scans it prints!!!

Now lexmark software if installed comes with a program to scan with. you need to check under your prgrams folder under lexmark for the scanning software that was installed with the print driver.

If you open the lid and you do not see the white light chances are your scanner has and needs a bulb inside and at the point to install one of these you might want to concider a new printer.

Please be considerate and leave your feedback and comments and ratings before you leave, Thanks

Dust inside the scanner, showing up as hairs and dust on the preview


Hello friend,
You must open your scanner and gently wipe the glass screen down with a cloth.. this should remove all dirt and make a clear scan.

How do I clean under the scanner head or glass? I get dust on scanned color photos at 300dpi and the glass is totally clean.


use a lint free cloth with a touch of rubbing alcohol or buy a tin of dust-off. The glass is nothing more than glass so don't be afraid of keeping it clean. You just need to be careful not to use anything that can scratch the surface. Be sure to leave the lid open to allow it to dry before scanning.

Canon DR-2050C Scanner gets verticle line down image


I have the same issue with mine and there are 2 image sensors on this scanner. 1 in the back that you will see when you open the front that has a meteal shield covering the top half, and one in the fold out front that faces the inside. These are the "glass" sections everyone is refering to. Problem is, they are plexiglass, not glass and mine has a tiny scratch in the lens that is causing the line. This could be your problem. find the lens and use a LED flashlight to inspect your lens for scratches. If its scratched like mine, the entire module has to be replaced to fix it. The canon part number is MH7-7038 and they range from $125-$160 if you replace it yourself. The one in the front is easy to do, but the back one is a little tricky. Hope this helps. E. Alexander, Field Tech, Cummins-Allison

Canon 9900f scanner glass removal


I would not worry about the underside of the glass unless you are having problems. The focal length of the ccd that captures the image is very specific and probably will not pick up anything under the glass. It is normal for the underside to look foggy but it will not hurt anything.

unless the warranty of your scanner has expired, you have to disassemble your scanner and clean the dust inside.
