Canon PIXMA MX870 - Scanner not working after Mac OS High Sierra Update

[rexus31]

Hello, I'm hoping someone can assist.

I recently upgratded the OS on my iMac to mac OS High Sierra Version 10.13.1.  I've noticed the scanner function on my MX870 (connected via wireless) will not operate.  When I click on Scan/Import photos or documents in the Canon Solutions Menu, I see the scanner icon bouncing in the tool bar at the bottom, then it disappears and I get the folowing error message:

MP Navigator EX quit unexpectedly.

Click Reopen to open the application again. Click Report to see more detailed information and send a report to Apple.

I'm not sure if this helps, but this is the first section of the report the system sends to Apple when the issue is encountered:

Process: MP Navigator EX 3.1 [3067]

What I've tried so far:

- Serached the Canon website for updated drivers or firmware but it says everything is up to date

- Powered the unit off/on

- Unplugged the unti for a minute, plugged it back in

Similarly, I had the same issue with the MX870 scanner.

When I attempted to scan documents from my Canon MX870 using a MacBook (High Sierra 10.13.2), I received the following error message "MP Navigator EX quit unexpectedly".

As recommended by an earlier contributor, I successfully began using Image Capture (default program for Mac). However, this was not as useful as MP Navigator EX.

Subsequently, I dragged MP Navigator EX to the Trash and reinstalled MP Navigator EX for 10.11.

MP Navigator EX is now working for me on 10.13.

Hope this information helps someone else.

My Solution was to reinstall the Canon IJ Network Tool. Before then, the scanner only worked sporadically: I had to constantly restart it to secure the wifi connection.

Canon, please update your drivers!

Ihave an iMac using Mac OS10.13.2 High Sierra. I had the same problem with MP Navigator quitting. However you can still scan using Mac software. Go apple/System Preferences/Printers & Scanners and click on Canon MX870 series. This brings up a scanner window which works for me.

Thanks passajero, Your solution works also with my Pixma MG 6100 series.

I am experiencing the same problem. Unable to print or scan with the Canon MX870. This printer was a work horse! Canon could have at least warned their customers they will no longer support this model for MacOSX development. Instead they left their loyal supporters of their products in the dark.

Most people would have bought new printers during the black Friday holiday sale (Nov. 2017) had we known. Amazon had a plethora of new printers (Canon and others for ridiculously cheap prices). HighSierra was released at the end of September and it is February 4th, 2018 and still no mention of what is going to happen regarding the MX870 driver.

I am really disappointed in Canon customer service. Just be honest guys! Do not keep us waiting in the dark. If you are going to write the driver and share it please do so. If not, just say this model printer is slated to be decommissioned from future support and be done with it. Communication with your loyal customer base is key to keeping your customers.

Keep the thread going and I hope more people add to it so Canon can just give us a straight answer. Thanks everyone.

Me Too... Devastating! Perfectly fine Printer/scanner headed to the dump!

Can you help us by posting the link for downloading the 10.11 driver? I am on Cannon website and can't find it... If this works I will be overjoyed! Can't afford to buy a new printer/scanner and I use the MX870 every day! Thanks!

[MacLove]

Thank you SO much! This WORKED!

Would be grateful if would post the link for downloading the 10.11 driver. MacLove seems to have received it but I cannot find it.

Same problem for me. I'm running High Sierra 10.13.3.  The Canon driver for 10.11 doesn't work for me.
