Are others experiencing Windows 8.1 scanner incompatibility with Imageclass D420 drivers?

bross1976 — Mon, 10 Mar 2014 20:18:14 GMT

Ever since I upgraded from Windows 8.0 to 8.1, the scanner function will not work on my Canon Imageclass D420 printer. I have installed the latest "8.1 compatible" drivers for the D420 and the MF Toolbox software, but I am still getting error messages in Windows stating that the drivers aren't working. I also tried making the Toolbox software work in compatibility mode for Windows 8, but that doesn't work either. Any suggestions?

Thanks

Hi bross1976!

I know this issue is frustrating and I will be glad to assist you.

I recommend uninstalling and reinstalling the drivers in 'Selective Startup Mode'. Please follow the instructions below:

1. Press the Windows key and 'x'.

2. Select 'Run'.

3. In the Run window type: Msconfig.

4. Select OK. If the UAC window opens, type in your password and select OK.

5. In the System Properties screen, choose 'Selective Start Up'.

6. Uncheck the box labeled 'Load Start Up Items'.

7. Click Apply.

8. Under the Services Tab, click on 'Hide all Microsoft Services' at the bottom of the window just above the OK button.

9. Click 'Disable All'.

10. Click Apply.

11. Click Close.

12. Restart the computer.

Next, to uninstall the drivers for your D420, please follow these steps: (If certain items are not listed or found, move on to the next step.)

1. Unplug the USB cable from the printer.

***Please leave the USB cable disconnected until you have uninstalled and completely reinstalled the drivers. Connecting the printer before going through the "Setup Wizard" may cause the Windows operating system to install a generic driver for the printer.***

2. Press the Windows key and 'x'.

3. Select 'Control Panel'.

4. Select Devices and Printers. The Devices and Printers window opens.

5. In the Devices and Printers window, right click on the D400/420 Series and select 'Remove' to delete the printer. Delete all of the icons for the D420.

6. Close the Devices and Printers window then press the Windows key and 'x'.

7. Select 'Control Panel'.

8. Select 'Programs and Features'.

9. Double click on driver to uninstall. Follow the on screen prompts. Repeat to uninstall the MF Tool box.

10. Restart you computer.

11. Leaving the USB cable disconnected, please download the driver from the Canon website using the following link: http://www.usa.canon.com/cusa/support/consumer

12. The site will automatically detect your operating system.

13. Next, select [Drivers] and the file [Windows 64bit] imageCLASS D420 MFDrivers (UFR II / ScanGear).

14. Click "I Agree - Begin Download".

15. Save the file to your computer. Once the download is complete, click "Run".

16. Click "I Decline - Go Back" on the Canon site and select [Software] and the file [Windows 32bit & 64bit] Tool Box Ver.4.9.1.1.mf16.

17. Save the file to your computer. Once the download is complete, click "Run".

18. Close the Canon window and go to the location on the computer where the files are saved.

19. You will see two icons with the name D420_MFDrivers_W64_us_EN_2.exe. Double click on the yellow folder icon. In the folder you will see two files with the name "Setup". Double click on the "Setup" that has the type [Application].

20. The "MF Drivers Setup Wizard" will open. Please proceed through the setup and restart the computer.

21. After the computer restarts, please connect the USB cable to the computer and allow the computer to finish the installation process. Once the printer is listed in [Devices and Printers], right-click on the icon and select it as the default printer. Please open a document on the computer and print it out.

Please follow steps 19 and 20 to install the Canon MF Toolbox 4.9 software. Once the software is installed, please follow the steps below to complete a scan:

1. Press the [SCAN] button on the control panel of the printer and place a document in the feeder.

2. On the computer, open the MF Toolbox program.

3. Select the [PDF] scan function.

4. Click the green [Start] button in the PDF window. The scan should begin.

After you successfully scan a document, please follow these steps to return your computer to Normal Startup:

1. Press the Windows key and 'x'.

2. Select 'Run'.

3. In the Run window type: Msconfig

4. Select OK. If the UAC window opens, type in your password and select OK.

Hi Patrice,

I have a Imageclass D480, Windows 8.1, MF Toolbox crash everytime I open it.

I followed your instruction exactly every step from "Selective Start Up" to "Uninstall Driver & MF Toolbox" then download & install new one along with restart PC each step as instructed.

Up to the step where I need to open MF Toolbox it crashes.

Scanning is still possible here

But I really need the full feature scanning of MF Toolbox. It used to work fine in Windows 8.

Hoping for a fix!

Regards,

Have to tried right clicking on the toolbox and selecting "run as adminstrator"? Before I would have this error code pop up but after doing that it works fine but scanning doesn't work when starting from the mf4880dw

nguyen2014 — Wed, 09 Jul 2014 00:03:15 GMT

I have tried "run as adminstrator" too, but still geting same non responding error.

Hi rickyaz.

Is the MF Toolbox open on the computer when you attempt to scan directly from the MF4880dw?

I look forward to your reply. Should you need immediate assistance, please contact us at 1-800-OK-CANON (1-800-652-2666).

Hi nguyen2014.

Since the error persists, even with installing the drivers in 'Selective Startup Mode', and running the program as an administrator, I recommend that you contact our live telephone technical support for further assistance.

Please contact us at 1-800-OK-CANON (1-800-652-2666). While I understand that the forum may be your preferred method of communication, these steps must be performed with a telephone support representative assisting you.

Thanks for your reply. The Toolbox is not open. When I use the "scan to pc" button, no scanning starts and it comes up with an error on the machine.

When I use the regular "scan" button, it displays a message saying that it can't find the toolbox software and I probably need to reinstall it.

I've installed the correct windows 8.1 version and have reinstalled in a couple times and no luck.

But when I run the program as "adminstrator" it works fine.

Check your windows\twain32 folder for old scanner drivers

stingray — Fri, 11 Jul 2014 13:11:39 GMT

We replaced our old Dell all-in-one printer that's no longer supported by Windows 8 or 8.1 with a Canon MF4700.

When we installed the drivers and the MF toolbox everything installed fine, but the MF toolbox would not start from the desktop. Same error as from the screenshot in one of the earlier posts in this thread.

Couldn't find a solution on any forums so we reluctantly called tech support. And we got a very helpful person on the line.

He suggested looking in the windows\twain32 folder for older scanner drivers that could be interfering with the Canon software.

Sure enough there was a Dell folder there from our install attempt of the incompatible printer, which the Canon has replaced.

After we moved that old folder out of the twain32 directory the MF toolbox worked normally.

Perhaps something to check.

Wow, it works!

Thanks stingray so much!

I check C:\Windows\twain_32 and see some folder and file not relating to my Canon D480, some with HP name in it too.

I temporarily move those out of twain_32 and try to start MF Toolbox, it start ok but can't scan with error.

So I also remove the D460 folder from twain_32.

Remove printer from Devices and Printers, replug usb cable, it reinstall driver automatically. New D460 folder show up.

Then toolbox & scan works ok now!

So happy!

Thanks for the suggestions, I have tried all that was listed. The uninstalled all other printers, and made sure the twain file was cleaned out again, then reinstalled with the selective start up. It prints, just won't scan. Toolbar clocks then says nothing is connected. Any more suggestions or do I need to get on the phone too?

Re: Check your windows\twain32 folder for old scanner drivers

rickyaz — Thu, 18 Sep 2014 07:50:33 GMT

Thanks for your reply. I'll have to check that out. I looked at my twain folder and have two listed which is odd.

Attached is a screen shot.

So should I delete both of those? And reinstall the entire driver. If something is wrong with this, how did it happen in the first place?

So basically I don't know if there should be two folders or if something is wrong what steps do I need to take to correct this.

Sorry for the late reply, thanks for your help.

nguyen2014 — Thu, 18 Sep 2014 21:51:27 GMT

I would suggest delete everything in that twain32 folder. Except .ds file probably wouldn't let you delete it then it's ok.

Then Remove MF4800 printer from Devices and Printers, replug usb cable, Windows should reinstall driver automatically. Expecting new MF4800 folder show up.

Then try toolbox and scan again.

Good luck!

This procedure was followed and used successfully for an imageCLASS D480 multi-function scanner/printer, too. I'm running the latest version of MS Windows 8.1 So far the Toolbox software allowed me to perform 2 scans - one as a PDF and one as a JPG.

Hi,

I have tried given in this forum as well as a few additional things that Canon support sent to me over email. However, nothing has worked so far. Here is what I have done so far

1. Followed the instructions in the forum for installing drivers which includes multiple restarts for Windows 8.1 computer

2. Set the MF Toolbox to run as Administrator

3. Set RPC Locator service in Windows to start automatically

4. Change the USB port which was used for the printer

5. Tried the Scan option in Devices and Printers but it does not bring up any dialog.

6. Talk to Canon technical support

The scanner works intermittently - typically after a re-install/restart (sometimes not even then). I am unable to use the scanner which for me is more important than printing itself (BTW the printer prints fine!).

According to the technical support person the problem is NOT with the printer but with my laptop (which is barely 6 months old). He even suggested that I re-install Windows in order to fix the problem.

I think the drivers rely on a outdated technology - RPC Locator service is a deprecated service is only kept in Windows for supporting legacy applications. I since so many people are experiencing this problem on Windows 8.1, Canon should provide a better solution/provide drivers which work with latest technology.

Any other ideas are welcome.

I'm now using my Canon on a Windows 7 computer and of course it works great. I don't know whose fault it is but I'm leaning torwards Canon on this. Canon has made no effort to update the drivers when clearly many people are experiencing the same problem. Go to Amazon reviews and most reviews mention the scanning problems. Can you imagine how hopeless all this will be or people who upgrade to Windows 10? Good luck with anything working. The only way I'll buy another Canon machine is if I see the Windows version stamped on the box.

sanjaykhandkar — Wed, 24 Jun 2015 18:31:20 GMT

Yes - that's right. The printer I am trying to scan with is an old one. The tech support person from Canon informed me that even if buy a new Canon printer - I will still have the same problem! As it is a problem with *my* laptop and not Canon's problem!

stingray — Wed, 24 Jun 2015 18:33:02 GMT

Take it back and buy a Brother printer. Much easier driver install and scan support from within the windows tool or the Brother tool. Canon makes great cameras.

Re: Are others experiencing Windows 8.1 scanner incompatibility with Imageclass D420 drivers?

rickyaz — Wed, 24 Jun 2015 18:35:54 GMT

I really like my Canon but to have a working scanning feature. Brother machines are well rated so I probably check them out next time.

Just registered on this forum to say thanks so much for the help, even though it was from over 2 years ago! An old driver folder in the twain32 folder was causing the MF Toolbox buttons to not work. They would just flash when clicked but they were not working - nothing else would happen...
