The scanner,which has not been used for about 1 year is scanning slides completely black except for 2 white lines,equal distance apart,down the middle,horizontally

If dirt sticks to the scan module, it will be scanned continuously and appear as a line in the output. Clean the glass with Isopropyl Alcohol. Dont use any other solvent.

The reason it has white lines is because the glass is dirty in the inside. If it has one speck of anything inside the scanner it turns into a line because it stays in that one place as the picture slides over it. So that line is actually a dot that is covering the picture throughout the scan. The solutions don't work. I don't suggest taking yours apart. I took mine apart and cleaned the glass. The pictures scanned fine and then the lines show up again. The real solution is to get your money back if you can. It will do this over and over. It's a design flaw in the scanner. The picture is actually squeezed as it it scanned. As pictures are squeezed against the glass... residue builds no matter how clean your pictures are.

Place the document or image into the scanner for scanning. A scanner with a paper feeder will only receive flat papers and photographs, but a flatbed scanner opens to accommodate books, fabrics and leaves along with flat papers. There is even a attachment for feeding photo slides into flatbed scanners.

Step 2 Start the scanning software. If the scanner does not engage the software automatically, press the "start" or "scan" button, or click the scanner icon on the computer screen to initialize the software.

Step 3 Activate the scan. Click the "file" menu and select "acquire," "import," or another practical choice that applies.

Step 4 Preview the item to be scanned. Most scanners have a preview option. This will show the scan area inside dotted lines. The lines can be moved with the mouse to relocate, enlarge or crop the scanning area.

Step 5 Set the resolution for images by number of dots per inch (dpi). For computer screen viewing, 100 dpi should suffice. Use 200 to 300 dpi for items to be printed.

Step 6 Use the appropriate setting for scanning black and white text. If the scanner does not show a preset for text, use "line art" or "black and white" at 300 dpi. Then use the optical character recognition (OCR) program to convert the image of the text into a file for word processi

Did you make changes to the scan type when you scanned the slides? It sounds like you have the scanner set to do a negative image as a slide would need.
Check the preferences for the scan type.
The scanning manual is available on Canon's Website.

Make sure the white document matt from uner the lid has been removed. Also in Epson scan make sure you have changed the document type from reflective to Film and Colour positive.

Most Mustek scanners have a black inside cover on the lid, this can give a black line down the side of the job.
ether cover the inside of the lid with white paper or place a bigger sheet on top of the sheet to be scanned!

the scanner assembly is getting blocked somewhere internally due to dust collected in the assebly.or it can be due to any of the wire internally gone loose or cut slightly so this problem.

Open the top cover to the scanner, the lock switch is on the left hand side of the glass. It is about 1 1/2 inches oblong and SLIDES back and forth. The switch is black with 3 lines across it. Are you able to see it now? And your answer is ????

There may have dust on inner side of the glass after the lamps.Try clean it.

Please do the following to scan slides or negatives in manual mode of the Epson TWAIN:
1) In the program you are working from, begin the scanning process. If working in full auto mode, as the scan begins you will see a message that reads TO CANCEL SCANNING IN FULL AUTO MODE AND SWITCH TO MANUAL MODE, CLICK CANCEL. At this point, click CANCEL, then MANUAL MODE.
2) You will now see all Epson Twain settings displayed. If the scanner has not previewed automatically, click the full page preview button (icon of a paper with one corner folded down).
3) Ensure the settings on the right hand side of the Twain are correct. For example, the DOCUMENT SOURCE for transparencies must be either TPU: COLOR NEGATIVE FILM, TPU: MONOCHROME NEG or TPU: POSITIVE FILM.
FILM here indicates that the item being scanned is transparent to light; this setting is also used for slide scanning. Positive indicates that the image is in true colors (ie the grass is green and sky is blue), whereas negative indicates reversed colors, as produced in some photo finishing processes. (If you are scanning a black and white slide in true colors, choose TPU: POSITIVE FILM as the DOCUMENT SOURCE and BLACK AND WHITE PHOTO as the IMAGE TYPE.)
If the DOCUMENT SOURCE is flatbed, the scanner will not activate the backlight in the transparency unit. If the DOCUMENT SOURCE is greyed out and you cannot select a TPU option, close the twain, reseat the power/communication cable connecting flatbed to TPU, then re-open the twain and try again.
4) Ensure the other twain settings are correct for the type of scan you are doing.
IMAGE TYPE should be color photo for all positive or negative color transparencies, or BLACK AND WHITE PHOTO for monochrome transparencies.
DESTINATION is unimportant, however you should select a RESOLUTION appropriate to what you plan to do with the scans. (There are no hard and fast rules for DPI. As a general guideline, if you are saving scans at original size, a resolution ranging from 400-600 DPI should capture enough information to faithfully record the image. If the slide or negative will be enlarged, you will need to increase this DPI accordingly. We have no guidelines on this; you will need to experiment and view the output to gauge the appropriate input DPI from the scanner.)
PREVIEW. If your scanner is doing an AUTOMATIC THUMBNAIL PREVIEW, the slides will automatically preview and appear in boxes on the left side. Here, you can select or deselect the slides you wish to scan.
If you recieve a message that the scanner could not find the film, click the CONFIGURATION button and uncheck AUTOMATIC THUMBNAIL PREVIEW FOR FILM, then OK, and try the PREVIEW button (page with corner folded down) again.
In this mode, you will have to manually marquee or crop the slides you wish to scan. Use the left mouse button to lasso one slide inside a box made of dotted lines, then click scan. Only the selected area will scan. Repeat this process (manually crop then scan) for as many slides or filmstrips are on the bed.
5) Click CLOSE once scanning is complete. The images will now transfer to the application in use.
