Re: cleaning

Unfortunately, cleaning dirt or debris from under the glass requires disassembly of the scanner and must be done by an Authorized Epson Servicer. Please refer to the Epson Customer Care Centers. if its still within the warranty period call epson.

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.

How to Clean Scanner Glass

Steps how to clean scanner glass

1. Unplug the power cord.
2. Clean the outer case with a cloth dampened with a mild detergent and water.
3. If the document table glass gets dirty, clean it with a soft dry cloth. If the glass is stained with grease or some other hard-to-remove material, use a small amount of glass cleaner and a soft cloth to remove it. Wipe off all remaining liquid.
4. Ensure that there is no dust on the glass of the document table. Dust can cause white spots in your scanned images.

*** CAUTION: Do not press on the document table glass too hard.

5. Be careful not to scratch or damage the document table glass, and do not use a hard or abrasive brush to clean it. A damaged glass surface can decrease the scanning quality.
6. Never use alcohol, paint thinner or corrosive solvent to clean the scanner. These chemicals can damage the scanner components as well as the case.
7. Be careful not to spill liquid into the scanner mechanism or electronic components. This could permanently damage the mechanism and circuitry.
8. Do not spray lubricants inside the scanner.
9. Never open the scanner case.

***NOTE: Wipe the inside of the document cover and the scanner's document table before scanning transparencies.

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.

Black line through the middle of the document

The thick line is either because of dust sticking to the glass or a module problem. Try different brightness settings and scan white paper. If the thickness varies and also the sides of the black strip are jaggered (step like) then it is dust on Glass. use isopropyl alcohol to clean, dont use solvents. If the teickness is same for all levels of brightness and has a sharp edge always, it could be scan module problem.

How do I clean the inside of the glass on the Epson 3490 Scanner?

Disconnect and remove the lid. Remove the two screws on the back of the base. Then use a screwdriver or flat blade to slightly open the back seam. Beginning at the back, run a blade up inside the upper part of the side seam. You will need to release three catches on each side. Once the sides are loose, raise the back of the top, while pushing forward, and the two snap catches at the front will release. The top then lifts off and you can clean the glass. Reassemble in reverse order.

Line going down page

Don't know if this is a solution per se but I replaced the glass bar (there is a part # on it) on the inside front of the scanner and still got a line. Then I played around with the back scanner glass and still got a line then I got in there real good and cleaned and when I scanned something it would show no lines until I saved the document then I got two lines. Thought it was my software going haywire but I did not give up, got some canned air and alcohol and cleaned the glass once again and blew out every part I could find and the problem resolved itself. Apparently the smallest piece of lint or dust, smudge or anything foreign on the scanner lenses will cause this line. But I love this scanner and I wasn't willing to give it up or pay $600 for a new one. Only had it a little more than a year. Persistence seems to be the key but check those little scanner bars and be careful, they are tricky to get out.

Underside of document table needs cleaning

Hey! I've just find the solution. The only thing you need is a multi-screwdriver to take out the two screws sitted on the backside, then use a screwdriver with a plain point to separate the dark grey plastic piece from the light grey one (use a few toothpicks to keep every flap open). When you get all the flaps open just pull the light grey piece (the bottom one) and separate the dark one with the lid and the glass. Now you can clean conscientiounly the glass. Be sure to put in its right place the back little plastic piece that covers the power connector before closing your scanner when it's clean. Close it introducing the front side before and pressing over every flap. Work done! enjoy you Epson scanner!

I apologize for my english, maybe I've used any unconvenient word, but I think you'll understand it.

There is some contamination on that side of the glass. Look on the side where you feed in the paper in the scanner.
Only takes a smallest of spots on the glass where the lamp parks in the document scanner mode.
Clean that throughly and see if maybe there is something on the bottom of the seal glass. Like i said, it can be a very small very hard to see mark on the glass.
