Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
What Windows 10 type do you have the 64-bit System Type, or the 32-bit System Type?
And also, is the printer/scanner installed as a USB-connected printer/scanner, or as a networked or wireless printer/scanner?
If there's a cable going to the printer from the computer
If the printer is within 6 feet of the computer
then it's a USB installation beyond doubt.
Please let me know, so that I may proceed.
OK! Thanks for checking on that detail.
Did the SCAN OCR function ever work, with this computer?
Did it previously work with this printer-scanner, but on another computer?
Did you install the printer, onto this computer, from a disc, or from a download, or did you just connect the printer to the computer with a cable and it worked?
Does the disc mention Windows 10, on its label? or only other Windows versions?
This model of printer, on Canon's website, has downloads listed for the
(which may or may not include scanning function)
and also a download for the
MP Navigator EX
program, which manages scanning.
Would you be willing to try an uninstall of what the disc installed for this printer, followed by a restart of your computer, followed by a re-install, from the Canon website, of the MP Driver and then the MP Navigator EX program? that has a chance of getting OCR scanning working. (Your disc probably does not have Windows 10 drivers on it. So it may not have installed properly, as to all the functions.)
If so, let me know, and I will give you exact instructions that will have the maximum likelihood, when followed, of producing a favorable result.
