Operating System:  Windows 10


Have the printer set up to using  USB cable.  This used to scan without a problem, but no longer works.  I get an error in the window of the printer that says:

" Set the PC to start scanning."    I have contacted Canon three times but still cannot get it to work.  I would consider setting it to use Wi-Fi, but don't know how to even do that. I cannot find directions for Wi Fi connection in the Canon manual that came with this printer.

The last help from Canon wanted me to change a bunch of settings in the Registry.  I do not feel comfortable doing that.


I would appreciate any help anyone might offer.  Thank you.

I would uninstall all of the Canon printer software you have that is related to this printer, go in to Devices and Printers in the Control Panel and remove the printer there, then restart your computer.


Go to the Canon Support Page for the Pixma MX870 and download the latest driver package, which shows up first, is dated 1/29/2016, and is 31.73 MB in size, then install that.  It should walk you through the entire setup process.  You will not want to have your printer plugged in via USB when you start the software.  It will tell you when to plug it in.  If you wish to set it up for wireless use it should also have a section of the installation that allows you to do that, and you typically do it while the printer is initially plugged in.
