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
Solved!

Hi jealkon,
There may be a third party scanner driver interfering with MP navigator.  Please try the following:
1.  Click 'Start' and then 'Computer'.
2.  On the left-hand pane, click the down arrow beside Local Disk (C: ).
3.  Click the down arrow beside Windows to open the folder
4.  Highlight the twain_32 folder.
5.  The folder should have 2 folders that start with PIXMA MX870 and a file called wiatwain.ds.  Any other folders or files should be dragged to the desktop. 
6.  Reboot the computer and try scanning again.

  • MP Navigator stopped working

    I have had the Canon PIXMA  MX439 for almost a year and it has worked perfectly until recently. A few weeks ago I started getting this message every time I try to scan: "MP Navigator EX has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available." Sometimes the scan still saves successfully to the folder and sometimes it does not. I'm not sure what made this start or how to fix the problem. I've looked online and tried some of the suggestions, but nothing has worked. My printer could beconnected wirelessly, but I've always used it hardwired.

    Hi mdolifka,
    There are several possible reasons for this error, but let's check the most common cause first.
    Follow these steps to check for any non-Canon TWAIN devices that may be conflicting with your scanner drivers:
    Click the Start icon and select 'Computer'.
    On the left-hand pane, double-click 'Local Disk (C'.
    Use the scroll bar on the left-hand pane to scroll down and then double-click 'Windows' folder.
    Use the scroll bar on the left-hand pane to scroll down and then double-click 'twain_32' folder.
    Under twain_32, right-click on the non-Canon model folder and select 'Cut'
    Use the scroll bar on the left-hand pane to scroll up and then click 'Windows' folder.
    In Windows folder, right-click in a blank any area and select 'Paste'.
    If prompted to provide administrator permission to move the folder, click 'Continue'.
    If prompted to provide permission again, click 'Continue'.
    Reboot the computer, open MP Navigator and try again.
    If this didn't work, or if you have any other questions, please feel free to Contact Us!

  • Canon 7D tethered stopped working

    When I click the shutter either on the camera or using LR, the message 'Transferring Files from Camera' stays and nothing happens.
    I'm pretty sure this stopped working after upgrading to LR3.5
    I upgraded to LR3.6
    Tried three different USB cables
    Tried each USB port with each USB cable combination
    Rebooted
    Followed every step here:
    http://kb2.adobe.com/cps/894/cpsid_89486.html
    Note, everything works fine using Canon EOS Utility
    I noticed someone mention upgrading to LR3.6C but I don't see where to download that. Wouldn't it be here?:
    http://www.adobe.com/support/downloads/product.jsp?product=113&platform=Windows
    Also, in this article:
    http://kb2.adobe.com/cps/842/cpsid_84221.html
    5D, 1Ds Mark II, 20D, EOS 350D (Rebel XT/EOS Kiss Digital N) on Windows require a driver downloaded from Canon. This driver is not available for 64-bit versions of Windows.
    Is it possible that the 7D should be included in that list?
    My setup:
    Sony VAIO laptop
    Window 7 x64 SP1
    Intel i5 2.67GHz
    4GB RAM
    USB 2.0
    LR3.6
    Is anyone else successfully shooting tethered with a Canon 7D?

    I'm happy to say that tethering is working after installing LR4.
    Thanks!

  • N97 Mini navigation stopped working

    I have N97 Mini (firmware 12.0.110.C01.01), and the navigation used to work very nicely, until recently.
    Funny thing is that it really gets the GPS lock. The voice guidance gives you the exact instructions where to turn and one of the screens work ok (the one, which shows the next action in symbols and writing). But the other screens are not updated. E.g. the speed indicator may freeze to some fixed value (today I was frightened when it showed 89 km/h in 50 km/h limit zone, while the voice guidance was still working, in reality it was below 50. It stayed 89 for as long as I was in the same screen).
    If I remember correctly, the background of the areas outside the map were black, when it worked. Now the background is grey.
    I have the Ovi -account active in the phone, internet APN is available and working. GPS gets the signal locked. But my location is not updated on the map.

    Your problems sound indicative of poor GPS reception. Have you considered an external bluetooth GPS receiver?
    Users should be aware that although it may still appear to function the use of "Bluetooth GPS' as a "Positioning method" is no longer officially supported by Nokia since OVI Maps v3.03
    Happy to have helped forum in a small way with a Support Ratio = 37.0

  • Canon 70D suddenly stopped working

    I recently shot a job with my 70D, came home and uploaded my photos with a card reader. Today, I reinserted my card and camera would not turn on. I put batteries, including my fully-charged backup battery, in charger. I inserted the two were fully charged batteries and it's still not working. I found out my 3rd-party batteries have not communicating with my camers. Only when I inserted my Canon battery in the single-battery postion, does it work. I just ordered two more Canon batteries 

    Hi zimbobway! Thanks for posting. Am I to understand correctly that you are using a battery grip with the camera and it will only power on with a single battery in the battery compartment of the camera without the battery grip installed? If so, are you also using a third-party grip or are you using a Canon grip?   Does the grip power the camera on when only Canon batteries are used in it?

  • Three finger navigation stopped working

    The last two days the ability to go backwards and forwards through web pages with a three finger sideways swipe across the trackpad has disappeared. Unclicking and reclicking it in System Prefs doesn't bring it back, nor does restarting Safari. I tried trashing ~/Library/Preferences/com.apple.systempreferences.plist but it still didn't work. Any other tricks to try out? This is on my MBP 13" with 10.6.1.
    Chris

    Try doing a PRAM reset, the instructions are:
    *Resetting PRAM and NVRAM*
    1. Shut down the computer.
    2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    3. Turn on the computer.
    4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    6. Release the keys.

  • Since upgrading to OS X Yosemite my Canon LBP3300 has stopped working ???

    With the above complete, empty the Trash and restart the Mac. Once you have logged back in download and install the CAPT v3.67 driver. When the installation has completed, open Printers & Scanners and add the LBP3300. Then see if you can print.

  • Mouse Navigation stops working

    This is weird. I have a multi-forms application running (6i and 10g). At some point somehing seems to happen and I cannot mouse click into any fields in the form. The only way I can move to a new field is with a tab or enter keys. Once this happens, it will be a problem for any new form I open. The only way it seems to fix itself is if I close the entire application and go back in. I put messages in and the 'When-Mouse-Click' trigger is firing. Any ideas?

    you are not the only one with this problem. Pls search in the forum. There are many posts with that topic.

  • My Canon i560x printer stops in the middle of print jobs

    My Canon i560x printer stops in the middle of print jobs when printing via Airport Extreme. Single-page jobs are fine, but the printer sort of runs out of steam on when printing multiple pages. It simply stalls with a flashing warning light, and if I press the resume button it spits the sheet out. The job remains in the queue until I delete it.
    This only happens when printing via the base station. If I connect the printer directly, it happily churns away, printing as many pages as I like.
    Is there anything I can do to fix this problem?

    For the record, though, I did actually do the search, ...
    OK, I let you off
    And it's not a Canon- or Tiger-specific
    problem, as I've also had similar problems with
    different versions of OS X, including Jaguar and
    Panther, and also with some HP printers.
    Now that is strange indeed. My Canon Pixma 5200 stopped working correctly the minute I upgraded to Tiger. Now I got the 5200R and it works beautifully.
    You've probably done all this already, still a few random thoughts:
    - Got the current Printer driver ?
    - Use Airport Express firmware 5.5.1 (*do not* use 5.6 or 5.7!)
    - Make a hard reset of the Airport base
    - Disable the Mac firewall (and set up the printer again)
    - Try all this with another (temporally) user account
    - Repair permission + restart before and after installing drivers
    Good Luck and let us know if (and how) you solved the problem.

  • "canon mp navigator ex has stopped working" cannot get this to work - fresh install on windows 8.1

    Trying to get LiDE 110 scanner working on my laptop. I keep getting this message once scan is complete "canon mp navigator ex has stopped working" and then a corrupted pdf is saved - fresh install on windows 8.1 I have used most up to date drivers and software and tried these two "fixes" from an internet search on this topic (it seems to be a common problem that hasn't been addressed by Canon) - I'm on the verge of returning the scanner!! 1) Delete this file: C:\Users\<user name>\App Data\Roaming\Microsoft\Windows\Network Shortcuts\My Web Sites on MSN.      RESULT - "My Web Sites on MSN" does not exist in that folder on my computer. 2)Remove "sdc330Twain.ds" from windows Twain-32 folder      RESULT - didn't have any effect Thank you, in anticipation!

    Currently running the scanner on "Advanced scan to pdf" but would like to have access to the canon software with more options 

  • Canon MX870 scanner stopped working

    The fax still works but scanner gives a "stopped working" error.  I have tried all the usual trouble shooting including going to the twain32 folder to check for third party interference.  Nothing has worked.  Any ideas?

    Hi katevancolen!
    So that the Community can help you better, we will need to know the Computer Operating System you're using (Windows XP/Vista/7/8 or Mac 10.x), and how you're connecting to your device (USB, Wi-Fi, or ethernet). Any other details you'd like to give will only help the Community better understand your issue! Thanks and have a great day!

  • MP870 MP Navigator EX 3.1 Error Message: "MP Navigator has stopped working"

    Hello
    I have a MX870 multi function inkjet. The scanned is the most important thing for me. BUt all of a sudden The software went crazy and cannot load. Everything was working fine up until a few weeks ago.
    The error message from Windows is: MP navigator has stopped working then it gives me the option to debug or close. Either way nothing makes it work.
    I am running it on Windows Vista Home Premium (service pack 2) . Device is connected via USB.
    I have read other posts about the twain 32 folder but they refer to other operating systems  such as windows 7.  I also tried reinstalling the software. In fact, the cannon website where you can get support does not seem to have the model MX870.  I had to select model MX876 which was the closest, in order to obtain a link to download the software.
    Please help

    PLEASE help!
