White spots on scanned pictures

There are white spots (looks like dust) on my pictures after I scan them and view them at 100%. Have never had this problem previously. Have cleaned the glass carefully and it still appears. Please help!

    white spots on scanned photos no dust on photo or glass. Canon is junk!

  • jonhenry Dec 17, 2008

    I just purchased a LiDE 100 it has the same problem. I scanned solid black photo. Looked like a starry night. Customer support was mystified, said it wasn't a known problem but will ship me a new LiDE 100 to replace it. I hope they are not all junk.

SOURCE: Documents scanned as 256 grey scale/TIFF show up as black pages.

Grey as you know is different shades of black. Uncompressed TIF can store this information. Compressed TIFF is not designed for this. Compressed TIFF is for blck & white only. Try JPG option. JPG can compress Color & Grey. For pure black & white chose TIFF compression.

SOURCE: CanoScan 5000F foggy glass

No problem.
1st step. Remove the lid. It just pulls out at the hinge end by lifting straight up, horizontal if you like. Where the two lid posts insert in the scanner body you will find 2 screws, undo them, no need to remove at this point, too hard. Rememeber you left them in there though.
2nd step. Around the 4 buttons at the control end is a striped trim panel that is the full width of the scanner. Locate the join between this trim and the light grey underside of the scanner body and just left and right of the COPY & EMAIL buttons, Using your fingernails lift with some gentle force. This edge will pop up. Note, the trim panel has 3 location tabs that insert under the grey border edge around the glass. So pop the front edge first and pull towards yourself.
3rd step. Once this trim is removed you will note 4 little grey plugs equally spaced under this area. remove the plugs and you will find 4 screws. Unscrew them, no need to remove, remember point above.
4th step. Time for CAUTION. You will be able to lift the upper part of the scanner up in which the glass is mounted. ***There is a lead with little play connected to the 4 buttons PCB which is attached to the upper panel. To ensure you don't damage it accidently when cleaning the glass you can remove the 2 screws attaching it to the upper panel.
5th step. See if you can wipe it, with a VERY SOFT LINT FREE cloth, without putting you finger on it somewhere......................
6th step. reassembly is the same in reverse

SOURCE: light stripe on scans

I have a Canon Lide 25 and I had a thin black stripe with a fat rainbow stripe in color mode and a bright light in grayscale mode.

I use canon scan toolbox, I checked the box for "display the scanner driver", in the advanced mode tab find calibration and click on execute.
If you have a different Canon scanner with a different software, look for calibration or adjustment.

How to have white background on small documents


All areas outside of the document will be black only. I don't know how you were getting white background.
If you want white background around your scanned image, a) stick the check (in this example) onto a white paper and scan the whole sheet. Ensure double detection is off. b) You can also do this in software, by cropping a larger area outside the scanned image.

There are many options to view the scanned image like Actual size or Fit or Fit vertically or Fit width. The same image will appear different in each case.

THERE IS A LINE ON THE RIGHT SIDE OF THE SCANNED COPIES, CANNOT SEE ANY OBVIOUS DIRT ON ROLLERS


Look at the glass strip through which the documents are scanned. Even a tiny spot there results in a dark line along the scanned image. Often such spots come from scanning a document with corrections made using the white correction fluid :)
The users manual (UM) describes the cleaning procedure on pages 61-62, you can get the manual here:

Unable to scan b/w neg's correctly using Digital ICE


Unfortunately, you cannot use Digital ICE on B&W films due to silver particles contained within the film. The Digital ICE future only works with C-41 (negatives) and E-6 (slides) processed films, but not B&W films.

DR-9080C BackgrounfColour Dropping Out


Color scanning is a big technology. There are concepts like Hue and intensity, refer to wikipedia for explanation. There is something called source light (your monitor for example) and reflected light (your picture that is being scanned). After scanning properly, say you view on a monitor where the Brightness & Contrast are not proper, you will see the image poorly! To test the scanning scan absolute white and check the output. It should read the values 255,255,255 for RGB (Red, Green & Blue). If the values are 255,255,255 but still the image does not appear white on the monitor, it is monitor setting that is wrong. If the output is not 255,255,255 then CANON service personnel only can help. Any good imaging software will display the RGB values.

CANON uses LED light source and they have fairly long life as compare to scanner bulbs. It is okay if you use a powerful system, but it has limited role as the scanner does all the jobs and it only sends the data to the Comp. May further processing is better withe high performance CPU and large RAM.

Line on Scanned Documents


There is a spot on the thin strip of glass that sits next to the large scanner glass. Because you are moving the paper when using the feeder, a spot appears as a line. Shining a flashlight on the glass can help you locate it. You can scrape it off with a finger nail or clean it with a damp cloth.

Scanning B+W shows dots


Don't use Descreen. That is for scanning things such as Magazines that, when looked at very close, appears to have a lot of little dots that can cause a moire pattern when scanned.

Dirty scans


Small white dots would indicate progressive failure of the CCD[sensor] or perhaps ingress of dirt to the inside of the glass. hard to say exactly with out seeing the machine.

You need to go farther than the lens glass. The dust is actually on the photo board itself. I'm assuming that the problem is on the bottom scanning side. You will need to dis assemble the scanner to remove the scanning unit. This can be done by remove the back, the sides, and the two front pieces. Once inside remove the silver metal cover over the rollers. This will help you get the actually scanning equipment out. Remove the black scanning unit behind the silver metal cover.

Make sure to ground yourself before continuing or you could short the boards.
Under the lens glass there are three boards. Two are visible. One is white, long and skinny. On the backside one is green. The one you need to get to is hidden between the black piece, and silver metal piece. There should be 6 screws that you will need to remove first.
Very gently pry the plastic from the metal. The problem that you are looking for is there.
Wipe the photo cells with an alcohol swab, and you should be good to go.

Epson 1640 SU problem, faint yellow line while scanning


Perhaps this: the scanner calibrates itself on a white strip above the place where the lamp is in rest. When there is a spot on that white strip, the scanner wil use the retreived information for the whole scan, resulting in a line on your scan.
