    <description>&lt;P&gt;Hi SEALboy.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;There are no known issues with the Windows 8 or 8.1 drivers.&amp;nbsp; The information you gave indicates that the USB cable is being unplugged while the machine is in the process of scanning a document.&amp;nbsp; If you remove the USB cable while the machine is processing a scan, it will result in an error and you will have to restart the computer and the printer.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Since you continue to experience issues, even after uninstalling and reinstalling the drivers, we recommend that you call in and speak with our live technical support technicians.&amp;nbsp; Please contact us at 1-800-OK-CANON (1-800-652-2666).&amp;nbsp; The real time feedback of a live technical support call would be very beneficial in this case.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I hope this information is helpful.&amp;nbsp; Have a good day.&lt;/P&gt;</description>

      <description>&lt;P&gt;When can we expect proper working drivers for Windows 8 and 8.1 x64 for this printer?&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Right now the scan function is extremely fickle and if the Toolbox fails to detect the scanner sometimes I have to remove the drivers and reinstall them (even a restart doesn't always work).&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;This is very frustrating as I need to scan documents on a regular basis.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;If this is the sort of support I can expect from Canon then I will never be buying one of your products again.&lt;/P&gt;</description>

      <description>&lt;P&gt;Hi SEALboy.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I apologize for the delay in response&amp;nbsp;to your question.&amp;nbsp;&amp;nbsp;Currently the drivers listed under Windows 8 (x64), at the Canon website, are compatible with Windows 8 and Windows 8.1.&amp;nbsp; They have been tested with the imageCLASS MF4450 and there are no known issues.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;There are a few things that you can check to verify if they are the cause of the issue, such as the length of the USB cable.&amp;nbsp; We don't recommend cables over 10'.&amp;nbsp;&amp;nbsp;If you have the device connected to a USB hub or switch, we recommend that you disconnect it.&amp;nbsp; I also recommend moving the cable to another USB port on the computer and if you experience the same issue with the USB port, replace the USB cable.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Should you still need assistance, we recommend that you contact us at 1-800-OK-CANON (1-800-652-2666).&lt;/P&gt;</description>

      <description>&lt;P&gt;There is a PDF file in the Windows 8 driver download that specifically says that the scanner driver will stop working under Windows 8 if you turn the printer off.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;EDIT: Here is the exact wording:&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;[Limitations During Operation]&lt;BR /&gt;When using the scan function while the device is connected to a computer by USB, removing the USB cable and then&lt;BR /&gt;plugging it back in or turning the device off and then on will cause the scanning function to be unable to execute. If this&lt;BR /&gt;occurs, please restart the computer.&lt;/P&gt;</description>

      <description>&lt;P&gt;I have similar problems. &amp;nbsp;The ONLY way to scan is to delete all of the Canon software, reinstall the Canon software, and then try again. &amp;nbsp;After a few attempts this usualy works, but it takes twenty or thirty minutes of this before scanning a one page document and then a few hours later when I try to scan something else it does not work. &amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Lately the unit does not want to print any more either. &amp;nbsp;If I send something to the printer nothing happens. &amp;nbsp;If I restart the compter three or four times, however, it magically prints the document that I attempted to print days earlier. &amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;It should be noted that this machine worked PERFECTLY when I was running Windows XP Pro and it barely works at all since I switched to Windows 8. &amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;It has been long enough now that Canon would have fixed this problem if they had any real intention of doing so. &amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Hi. I have the same text in a PDF that is included in the driver package.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;These words are straight from Canon: When using the scan function while the device is connected to a computer by USB, removing the USB cable and then plugging it back in or turning the device off and then on will cause the scanning function to be unable to execute. If this occurs, please restart the computer.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;They don't mean During Scanning. They mean Ever. My Canon works perfectly with every machine But my Win8.1 machine. This is an issue with the drivers. Kindly reply.&lt;/P&gt;</description>

      <description>&lt;P&gt;The message below refers to removing the USB cable or turning the machine off in the middle of an active&amp;nbsp;scan:&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;[Limitations During Operation]&lt;BR /&gt;When using the scan function while the device is connected to a computer by USB, removing the USB cable and then&lt;BR /&gt;plugging it back in or turning the device off and then on will cause the scanning function to be unable to execute. If this&lt;BR /&gt;occurs, please restart the computer.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;If you are using Windows 8.1, there was an update to the operating system a few months&amp;nbsp;that may have caused issues with scanning from the Canon MF Toolbox.&amp;nbsp; I recommend uninstalling and reinstalling the drivers in 'Selective Startup Mode', and then setting the MF Toolbox to run as an administrator.&amp;nbsp; Please follow the instructions below:&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;To place you computer in a Selective Start Up, please follow these steps:&lt;/P&gt;&lt;P&gt;&amp;nbsp;1.&amp;nbsp;

Uncheck the box labeled 'Load Start Up Items'.&lt;/P&gt;&lt;P&gt;&amp;nbsp;7.&amp;nbsp; Click Apply.&lt;/P&gt;&lt;P&gt;&amp;nbsp;8.&amp;nbsp; Under the Services Tab, click on 'Hide all Microsoft Services' at the bottom of the window just above the OK button.&lt;/P&gt;&lt;P&gt;&amp;nbsp;9.&amp;nbsp;

      <description>&lt;P&gt;[Con't.]&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;After restarting the computer, please follow the instructions below to set the Toolbox to run as an administrator:&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;1. Open the&lt;SPAN&gt;&amp;nbsp;&lt;/SPAN&gt;&lt;SPAN&gt;Windows&lt;/SPAN&gt;&lt;SPAN&gt;&amp;nbsp;&lt;/SPAN&gt;desktop.&lt;/P&gt;&lt;P&gt;2. Right click on the MF Toolbox icon and click properties.&lt;/P&gt;&lt;P&gt;&lt;IMG width="248" src="http://kbsupport.cusa.canon.com/system/storage/1/kb/attachments/embedded/15235_image_1.gif" border="0" height="323" /&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;3. Click the Compatibility tab, then click "Change settings for all users".&lt;/P&gt;&lt;P&gt;&lt;IMG width="380" src="http://kbsupport.cusa.canon.com/system/storage/1/kb/attachments/embedded/15236_image_1.gif" border="0" height="509" /&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;4. Put a check next to "Run this program as an administrator", then click Apply and OK.&lt;/P&gt;&lt;P&gt;&lt;IMG width="373" src="http://kbsupport.cusa.canon.com/system/storage/1/kb/attachments/embedded/15237_image_1.gif" border="0" height="487" /&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;5. Click OK again on the&amp;nbsp;properties screen.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;The MF Toolbox should operate normally.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;If the error persists, or you need further assistance, I recommend contacting us at 1-800-OK-CANON (1-800-652-2666).&lt;/P&gt;</description>

      <description>&lt;P&gt;I did all the steps you suggested, in the order provided. I couldn't believe that the scan (your previous post) worked.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;But then when I re-enabled startup scripts and restarted, I could no longer scan.&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;So I'm right back where I was, having followed every one of your suggestions.&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;It seems like all the people on here might be on to something, and there is an error in the driver. Would you please ask someone at Canon just to test it?&lt;/P&gt;</description>

      <description>&lt;P&gt;For reference, I have a 4350d, but it is the same issue every single other ImageCLASS user is having on Windows 8.1.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Like them:&amp;nbsp;&lt;/P&gt;&lt;P&gt;1. I have a windows7 machine that runs the scan function just fine&lt;/P&gt;&lt;P&gt;2. My windows8.1 machine runs the PRINT function fine, but NOT the SCAN function.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;So, please, escalate this so someone at Canon can release a driver that works with this OS for all functions of the multifunction device.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Thanks Patrice!&lt;/P&gt;</description>

      <description>&lt;P&gt;I called Canon, who asked me to go into Services and try to Stop my WIA service. I couldn't do it. Turns out there is something wrong with Windows 8 that affects some devices but not others.&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I switched&amp;nbsp;WIA to manual and restarted.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I scanned successfully!&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I unplugged the printer from USB. Then I replugged it in.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;No more scanning.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;So Windows can obviously drive the scanner, but&amp;nbsp;&lt;EM&gt;something is wrong with the driver&lt;/EM&gt;.&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Hey James&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I spoke to them. They said that WIA is not working correctly. Except it is, because I can scan. But only once. Because there is a driver problem.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I hope this helps you get this in front of the developers!&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Matt&lt;/P&gt;</description>

      <description>&lt;P&gt;I called again and got the same walkthrough and puzzlement. "It should work" appears to be Canon's diagnosis. It does...just not with the driver Canon made for WIA on Windows 8.1!&lt;/P&gt;</description>

      <description>&lt;P&gt;Any chance of getting an updated driver?&lt;/P&gt;</description>
