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.
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.
Activate the scan. Click the "file" menu and select "acquire," "import," or another practical choice that applies.
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.
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.
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
Don't scan from the Canoscan toolbar. Use an imaging program (I used Picasa), import from the Canoscan, and Scangear opens up. In the settings for Scangear, you can choose positive or negative film (use positive for slides). You can keep using Scangear, or after using it once, you'll see it has corrected the problem with the toolbar
I had the exact same problem! the problem seems to be with the CCD calibrating itself before it starts to scan.
you look into the scanner, the scanner glass extends itself into the
casing of scanner where the CCD rests. Every time before the scan starts
the CCD starts to calibrate itself in its housing before it starts to
scan. If there is any reminiscence of dust or anything object (like a
piece of paper) stuck in the edges where the CCD rest, the white
balancing is thrown off and it causes white lines to appear along the
entire line where the dust was present.
Ideally the solution
would be to open the scanner casing to clean the housing where the
scanner CCD rest. This would solve the problem.
If you are unable
to open the scanner casing, then try using a piece of paper or a thin
edge of a cloth, slightly dampened to reach into the edge of the scanner
glass where the CDD rests and clean it. This is what i did and this
solved the problem.
i think your batch's thickness is high. so that when you are keeping your batch on the scanner then your cover will be not covering properly. so that the external light will be passing through the gap between scanner and cover. so that your scanning is showing black. if you want to scan your batch, then you have to cover by plane paper around your batch on the scanner. otherwise you try to protect out side light on the scanner glass. now you can get proper scaning.
if the unit makes color copies correctly, the scanner is working correctly, the application you are scanning to sets the size, resolution, color/b&w, etc. you will need to enter into the application and set it for color.
This sounds like you are trying to scan images at a larger size than they actually are? I am not an expert-(but I have a Mac)-but from what I'm reading, scan your photos at a 300-600 dpi resolution, then use photo editing software to enlarge them. The higher the resolution, the more disk space and the more photo detail (i.e. cracks, dust, scratches, paper type) will be captured, and the more time it will take to scan. Also, for the white, does your scanner allow you to select the area/define borders during the pre-scan? Mine lets me drag borders to just the image area (but capture the image first, then do the cropping and editing to a copy later). Rookie2112
