Canon MP Navigator Stopped Working (MX870)

Running Windows7, 64 bit Oper System

Canon MX870

Scanning was not an issue prior to a few days ago. No new software or programs have been installed.

Went to scan a document and scanning looked like it was working, then it greyed out and received error message: Canon MP Navigator EX has stopped working.

Searched internet for solutions and tried them. Nothing works. I've gone as far to un-install all Canon products and utilities, even went into registry and searched and removed everything I thought I could related to Canon.

 

Still receive error. What do I do now?

 

Guess I've pretty much stumped the panal since there's been no response

You're right!! This is just too bizarre. I put a shortcut of the Navigator folder on my desktop so I can find my scanned docs easily and move them. But this is just a work around - until I can get a new printer/scanner. Thanks for passing this along.

your welcome 🙂

I experience the same issue on my win7 64bit computer and spent several days searching the web reading this forum and trying suggested fixes. I had tried the twain_32 folder, the removal of any MSN files technique, reinstalling and still could not get it to work. Short of one suggestion of a corrupted profile and attempting to do a recover on it I decided to start systematically removing apps like Dropbox, Google Drive and online backup software (MyPCBackup) I had. What lead me to look at these type apps was a call into tech support where they asked me to remove the Google Drive to see if that would fix it. Well on my removal of the backup software I had the MX Navigator starting working. I since reinstalled Dropbox and everything still working as expected.

 

I have a MX870 printer and the version of the navigator software is 3.1.

 

FYI here is an oddity prior to removal of my apps if I attempted to start  the Navigator software over and over around the 8th time it would start.

Jon,

 

I just recently installed "Smart Notebook" and now my scanner isn't working.  I am not understanding what I need to do though to get it up and running again.  Any help you could give me I would really appreciate it. 

 

Thanks,

Dara

After searching for weeks and following all the suggestions to no avail, another fix is in the link below IF you use justcloud software - followed this and fixed my problem

Hi Dara

 

if you navigate to  C:\windows\twain_32 you will see a file called sdc330Twain.ds, delete it and you should be able to scan again.

Wow after 3 hours of trial and error, uninstall, reinstall, restart...I took your advise and uninstalled MYPC Backup and MP Nav 3.1 w Windows 7, USA works again!  change compatibility to Windows7. Turned off Malware, AVG.

Had the same problem and obviously many others have as well.  Seems like some solutions work for some but not others.  After unintalling, reinstalling several times as well as checking the Twain_ds file, nothing worked.  Spent 90 minutes with tech support and finally was asked if I had any backup software.  As soon as i uninstalled Justcloud, the scanner probelm was solved.  Also, after reinstalling Justcould and changing settings the two programs are compatible.  In Justcloud, go to settings, explorere integration and uncheck the context menu and sync folder overlay boxes.  Hope this helps others.

Thanks I will try this.

Thanks Jon it worked!!!!
