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.
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.
Are the scan settings correctly specified for the scanning application software used? Check if interface cable are correctly connected.When the error occurs on ADF front, clean the glass inside of Base Unit. When the error occurs on ADF back, clean the glass of the Upper Unit.Check if any dirt get on the white reference sheet?
Also, check the mirror of the OPT Unit dirty, clean the mirrors. Check the connector and check any cables are damaged,if so, then replace the damaged cables.
If the above doesn't help, then the issue may be due Optical unit or Control PCA problem. hence, you may have to seek the help of Fujitsu scanner technicians for rectification.
This is acutally easier than it looks. I just had the same problem with a cloudy film starting to form underneath the glass on my older HP 4400C scanner.
First completely remove the hinged top lid by lifting straight up on both long ends of the lid - notice the 2 hinges on the back end of the lid will come straight up and out of the body of the scanner, still attached to the lid.
Next look down inside the 2 hinge holes (on the main body of the scanner where the lid hinges just came out of) and you will see a screw in each hole. Remove both screws using a phillips screwdriver. This will allow the rear end of the scanner to come apart enough so you can now lift it up a few inches to separate it and get your hand inside there to clean the underside of the glass with a soft cloth - BUT JUST REMEMBER THE FRONT END OF THE SCANNER WILL STILL BE CONNECTED, so don't pull it too far apart because it could snap and break something that is still holding the front end together. (I could not figure out how to separate the front end piece, and then I realized I didn't have to).
So on the rear end of the scanner, now carefully pull the light upper colored plastic apart from the lower dark plastic just enough so you can get your hand inside the compartment and use a soft cloth to clean the underside of the glass. I just used a small piece of an old cotton t-shirt with a couple little dabs of water on it and then just kept rubbing the dirty areas on the underside of the glass over and over until all the dust film/streaks disappeared and the glass was once again clean and all clear.
Then gently lower the glass back down and line up the plastic pieces together on the rear end and put the 2 screws back in the hinge holes, and then reinsert the hinges in their slots and lower the lid back on top of the scanner glass and it is ready to go again !!
1. Scanner lamp has failed or does not come up to full color temp
2. Scanner attempts to initialize, which means it must move a bit to what is the "home" position where the scanner actually reads a very small coded imprint on the underside of the glass. If this area is too dusty or dirty, that will cause this problem, but also if the scanner motor and worm drive are binding for any reason, such as the scan rails internally being too dry this will also happen.
Locate a service manual and remove the copy glass by removing the lock guide on one side, the glass should lift partially, allowing some gentle cleaning with soft cloth and glass cleaner. Do not attempt to force the scanner to move inside, as it is worm gear driven and such an attempt will strip the nylon gears or worse.
Follow the manual instructions if you need to fully remove the top cover, glass and platen assembly for cleaning. It is very simple once you are in the interior...but gentleness and care are necessary.
Sadly, parts are difficult to find for all scanners now, and it is often far more economical to replace with a new, low cost and higher performing, higher rez unit for $ 120 or less. Often a lot less.
You mean the inside of the scanner glass? (The platten is a part of the print unit),
You'll have to remove the sides and read cover. Unplug the scanner wires and remove the scanner assembly. Separate the document feeder from the scanner bed. Open the covers of the scanner bed (usually there are screws holding it together). Remove the glass and clean it. Reverse the process to reassemble.
Be careful. Canon multipasses are built a little like a Chinese puzzle box. There are little snaps everywhere as well as screws. Watch out you don't force anything and cause the snaps to break.
OK Just Stupid (G).... Open the lid, pull it up and off and you will see two screws below the hinges. If you have decided to purchase another scanner already, you are clear to proceed. Take these out, pry the halves apart until you hear a click. Push the upper section toward the control panel and the will come apart like a freshly caught oyster.
I would not only clean the inside of the glass, but would get a can of compressed air and blow the heck out of the area below the black thing. This should get most of the dust off of the mirrors (3).
I took mine apart and cleaned them, but, if you had problems opening the case, I definately would not try taking this assembly apart. It'll make you cuss.
hi im jules_09,the scanner glas should not be remove from the unit because if it is remove you might get a error code,so just get a soft cloth or a any kind of tissue and table tissue will do then apply a glass cleaner on it then gently rob it on the scanner glass until the glass is clean just make sure the unit is off and ulplug.if the scanner glass is cleaned
