Hi, You may need to calibrate a new CIS with new Assembly. Later on this new assembly can be removed and your old one will do. Assembly means solonoid+ shading sheet. This will work for sure Samir Dhingra 9820800633

We have a Canon DR-9080C scanner. When scanning in Duplex on pages with data on both sides, the back side of each page is coming out unreadably faint. The header and any overall large blocks of black on...


The Canon DR 9080C is a 'contact' scanner. There is no optical lens, instead it uses a technology called "Contact Image Sensor' or CIS. The page to be scanned must be close to the glass for a proper image. This is achieved by a full-length rubber roller just above/below the scanning module. The roller is spring loaded and in case it gets stuck, there wont be enough pressure on the document to keep it close to the glass. ensure these rollers are moving smoothly and if required clean them. The rollers are on the opposite of the Scanning module.

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.

Line in scanned document


Its dirt! It takes just one tiny speck of dirt on the lens to make a vertical line.

We have some scanner maintenance videos;you want to clean the CIS front sensor.

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.

No image after scanning


The paper sensor must be checked. Check if there is a speck of paper stuck inside the sensor. Blow with a vacuum cleaner.

Scanned image has a line running through it


This could be one faulty sensor pixel or a speck of dirt on the scanner bar. It might be worth opening the scanner and carefully dusting the bar with a camera cleaner aerosol.
