Drivers are the piece of software that enables the communication between the computer and the scanner. It is seen that in fifty per cent of the cannon scanner not working problems, out of drivers were the real cause behind the issue. Contact tech support at 187 to get technical help if that is the case. Another reason behind the problem can be a broken glass surface. Check to see whether it starts to work or not. Applying only gentle pressure on the glass so that it does not gets damaged. To troubleshoot this cause first of all use a chemical agent like Collin spray with a clean cloth and clean the surface of the scanner glass. Whitening agent or glue from papers can get stuck to the glass because of the heat machine produces. Other problems with the glass like any technical issue from inside can also lead to the canon scanner not working issue.

If your scanner is not scanning the document properly or there is some other problem with the scanner then it is possible that the glass of the scanner machine is not clean. Also make sure that the cables you use are from canon as he canners with work properly only with original cables provided from scanners. You need to replace such faulty wires and cables. If the scanner is not working even now it is possible that any of your wires are damaged from inside. When both the cables are connected properly the scanner should work. If the power cable is all right then the USB cable might not be properly inserted. If it is not okay then that is the reason for your problem. First of all, check whether the power cable is properly inserted or not.

Improperly connected cables can be a big reason for the canon scanner not working issue.
