Canon MX490 Cannot communicate with scanner

Hi,                                                                       November 10, 2017


I have had the MX490 for a year. Today, a neighbor needed to borrow my USB cable from my Printer/Scanner.


When I re-installed the USB cable and go to make a scan I get the message:

Cannot comminicate with scanner for this reason

-Scanner is turned off

-USB cable is disconnected

Code 5, 156, 69


The USB cable is connected and ther printer/scanner is turned on.

I am able to make prints from the internet with the printer but I get the above message when I try to use the scanner.


I re-nstalled the driver but that doesn't help.


Please help me resolve this issue.
