About 99% of the time, there is something stuck on the lens. Our clients that use these are hard to convince of this, but often if you take a small flashlight, you can either find something stuck on one of the lenses or there's a scratch on one. If it's scratched, you're out of luck and will have to replace it. Otherwise, use a light alcohol based pad and clean with it wrapped around your fingernail. Kodak scanner cleaning supplies work great.

Scanning half a page


You will need to check your page settings. As each program is different, the page setup will generally stay the same. It will also change if you are scanning at 0, 90, 180, or 270 degrees as well.

I have a big black line down the middle of my scans


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.

My Canon DR 7580 has image void in the front image. Looks like two void columns. The Image reader is clean. Can the upper and lower imager be swapped to see if the problem is the upper imager?


You cannot swap upper and lower images. You can scan the page twice (in duplex mode) by reversing the same. Ensure which side is giving perfect output.
DR 7580 is a CONTACT scanner and hence the paper has to touch the glass surface properly. There are two full sized rollers, just above/below the scanning module, which does this job. Ensure that they are proper and there is enough pressure, press and release 3-4 times to check it is stuck.

Need the part number for the scanner led array? getting lines on scans not all led's are turning on and just need to order the new array. Its the upper array on the canon scanner dr 7580


MG1-3616 is the part number for the entire reading unit. I am not aware if only the LEDs are available separately. It is very unlikely that only some LEDs are working. Ensure glass is clean.

Canon dr-7580 scanner how to initialize cis


If the Black lines are jaggered and are vary in size with different levels of brightness, then most likely it is scratch on the glass. If the lines are sharp and perfect and does not change when different brightness is chosen, then it could be failure of CIS module (Try this under B&W mode). To the best of my knowledge there is no concept of initialising the CIS, you may need to clean the Shading sheet.

Your hard disk must be almost full. Direct the scanning software to send data to a hard Disk location where you have enough space.

Canon dr 7580 is not scanning multiple pages.


Check if you have selected 'multipage' option. Then you will get only a single file, but with multiple pages.
If your question is that the second or subsequent pages are not pulled in for scanning, then you need to change the rubber rollers.
