Scanner Troubles - Canon ImageFORMULA DR-C125
There was a problem with my Canon ImageFORMULA DR-C125 yesterday.
When I scanned the first few pages of the 10-some books I just tore apart, it showed the error message "A double paper-feed has occurred. Please check the document and the scanned image on the display and scan the document again" even though there was clearly no double paper feed at all. After a several attempts which all resulted in the same message, I did everything that I could think of - turned off and on the scanner, cleaned inside the scanner, rebooted PC and etc. but nothing worked.
So I went to Canon's website and downloaded the latest version (Ver2.3) of the CaptureOnTouch application to install. After some more struggle on some stupid reason, this re-installation of the software did the trick and I could scan pages no problem.
Above mentioned another struggle - after re-installing the application, I thought there was a new option in the PDF setting screen, which was to let you choose whether to make the document compatible with PDF/A format. Naturally I selected this option thinking it wouldn't do any harm, which actually turned out to have been kind of a mistake - it limited the subsequent OCR language options and there was no Japanese (I was scanning Japanese books).
I thought updating the CaptureOnTouch software caused this problem so I again removed the software and then re-installed the original version, which didn't solve the problem until I deselected the PDF/A compatibility option (well, it wasn't a new feature for V2.3). It only took me about three hours to sort all these out... The scanner has been working fine.
Just thought there might be someone who is facing the same problem.
