Some Windows users are encountering the ‘A problem prevented the document from being scanned‘ every time they attempt to scan a document with a connected scanner. If the user clicks on Preview, they are greeted by this error instead: ‘A problem prevented the document from being scanned.’
There are multiple bottom-line culprits that might end up causing this error:
- Generic glitch – You might encounter this particular issue due to a generic glitch caused by long idle periods. In this case, you should be able to fix the issue by initiating a power cycling procedure in order to clear any temp data that might be causing this issue. Additionally, you can attempt to run the Printer troubleshooter to see if any of the automated repair strategies will fix the issue.
- Windows Image Acquisition service is turned off – Scanning jobs won’t be processed unless the WIA service is running. If it’s disabled or if it’s stuck in a limbo state, you will need to restart it and configure it to remain open before you’ll be able to complete any scanning jobs on your computer.
- Insufficient permissions – If you’re encountering this error while attempting to complete a scanning job via the Windows Fax & Scan utility, try opening the application with administrative privileges and see if this manages to fix the issue for you.
- Install & Alignment job not completed – In case you’re seeing this error with a new printer, chances are you will need to complete the cartridge install and alignment by printing a test page before your printer will let you scan anything.
- Old printer/scanner is connected to USB 3.0 port – If you’re facing this issue with an old scanner, you might need to switch to a USB 2.0 connection in order to eliminate any incompatibilities facilitated by the new USB format. Additionally, if you’re using a front USB, switch to a rear one to ensure that the device receives enough power.
- Corrupted OEM scanning app – This problem can also be caused by a corrupted scanning app. If this scenario is applicable, you can circumvent the issue entirely by using a proprietary scanning app like HP’s Scan Extended utility or by downloading and using the UWP version of Windows Scan from the Microsoft Store.
- Corrupted Still Image key – Under certain circumstances, this particular error code can be caused by a corrupted key (StillImage). In this case, you can fix the issue by using the Registry Editor utility to navigate to its location and delete it.
- Bad USB cable – It’s also possible that a non-congruent or corroded cable might end up causing this problem. Replace it with a new one laying around in your house to see if you need to order a replacement or not.
- System File Corruption – In rare cases, this particular issue might end up being caused by some underlying system file corruption. In this case, refreshing every OS component with a clean install or repair install (in-place repair) will surely fix the problem for you.

Method 4: Running Windows Fax & Scan as Admin
As it’s been reported by some affected users, this problem can also occur due to the fact that the application you’re using to que your scanning jobs doesn’t have admin access in order to send the information to your scanning device.
If this scenario is applicable, you should be able to fix the issue by ensuring that the default scanning app (Windows Fax & Scan) is forced to run with administrative access.
Here’s a quick guide on doing this:
- If Windows Fax & Scan is already opened, close the application, but make sure that your scanning device stays open.
- Press Windows key + R to open up a Run dialog box. Next, type ‘ wfs’ inside the text box and press Ctrl + Shift + Enter to open it with administrative privileges.
- When prompted by the User Account Control (UAC), click Yes to grant admin access.
- After the Windows Fax & Scan utility is opened with admin access, queue another job and see if you’re still encountering the same error.
If the same ‘A problem prevented the document from being scanned’ error returns, move down to the next potential fix below.
Method 5: Finishing the printer’s cartridge install & alignment
In case you’re encountering the issue with a brand new printer (not a standalone scanner), ensure that you have completed any requirement that the printer asks for. Some users that were facing the same issue have confirmed that they’ve eliminated the error by completing cartridge install and alignment.
With most printers, you will need to physically print the scan and alignment page before the printer will let you scan anything. Of course, the steps of doing so will be different depending on your printer’s manufacturer. Some models will allow you to do this from their proprietary utility, but you should also be able to print an alignment page via the physical buttons of the printer.
Note: If you’re not sure about how to do this, read you’re printer’s user manual or search online for specific steps on aligning your printer.
In case you did this to no avail or this scenario is not applicable, move down to the next potential fix below.
Method 6: Connecting scanner to USB 2.0 port
In case none of the potential fixes above have helped, you should start investigating the port you’re using for your printer/scanner. Is it plugged in the front/rear? Is it a USB 3.0 port or 2.0?
Keep in mind that if you’re using an older scanner model, it might not be configured to work with the newer Univeral Serial Bus 3.0 interface. This problem is recurring and it’s affecting both printers and scanners released before the apparition of USB 3.0.
In case you’re using a USB 3.0 port for your scanner, switch to a USB 2.0 port and see if the issue is still occurring.
Also, in case you’re using a front USB port, switch to a rear one – Front USB ports tend to provide less power than their real equivalents.
Method 7: Using Scan Extended utility (HP Only)
If you’re encountering the issue with an older HP scanner model, you might need to use their proprietary scanning feature in order to avoid the ‘A problem prevented the document from being scanned’ error.
Some HP users have confirmed that they managed to fix this issue by installing and using HP Scan Extended as an alternative scanning solution.
Important: This software is proprietary and only works with HP printers.
If this scenario is applicable, here’s a quick guide on installing and using the HP Scan Extended in order to circumvent the error:
- Access Official HP HD Scan to download the HD Scan Extended utility.
- Once the download is complete, open the HPScanExt.msi file, accept the End-User License Agreement, then follow the on-screen prompts to install the utility.
Note: When prompted by the UAC (User Account Control), click Yes to grant Administrative privileges.
- After the installation is complete, click on Finish and restart your computer if you’re not prompted to do so automatically.
- Once your computer boots back up, click on Start and search for ‘HP Scan extended‘. Then click on the utility from the list of results.
- Create a new Scanning job and see if the operation completes without the same error.
In case this method was not applicable, move down to the next potential workaround below.
Method 8: Using the Windows Scan app (Windows 10 Only)
if you’re encountering the issue on Windows 10, there’s one additional workaround that you can try. As it turns out, Microsoft published a UWP application (Windows Scan) that you can potentially use to avoid the ‘A problem prevented the document from being scanned’ error.
Some users have confirmed that using this Scan app instead of the OEM equivalent allowed them to complete the scanning jobs with no issues.
Here’s a quick step-by-step guide on installing and using the Scan app on Windows 10:
- Press Windows key + R to open up a Run dialog box. Inside the text box, type ‘ ms-windows-store://home’ and press Enter to open up the Home screen of the Microsoft Store.
- Inside the Microsoft Store, use the search function (top-right section) to find the Scan App. Then, click on it from the list of results to open it.
- From the next screen, click on Get to initiate the download of Windows Scan.
- Wait until the installation is complete, then click on Launch to open the utility.
- Next, follow the on-screen connections to connect a scanner and see if it allows you to circumvent the error message
If the same problem is still occurring, move down to the next method below.
Method 9: Deleting the StilIimage key
As it turns out, you might also encounter the ‘A problem prevented the document from being scanned’ error due to a corrupted Registry entry that ends up preventing the scanning jobs from being executed. This problem is typically reported to occur after an AV ends up quarantining or removing OS items.
Several affected users that were facing this error with Canon printers have confirmed that the issue was resolved after they used the Registry Editor to delete the StillImage key. Most of them reported that the issue was resolved after they rebooted their computer.
Here’s a quick guide on deleting the StillImage key in order to fix the ‘A problem prevented the document from being scanned’ error:
- Press Windows key + R to open up a Run dialog box. Next, type ‘regedit’ inside the text box and press Enter to open up Registry Editor.
Note: When prompted by the UAC (User Account Control), click Yes to grant administrative privileges.
- Once you’re inside the Registry Editor utility, use the left-hand menu to navigate to the following location:
Note: You can also get there instantly by pasting the location directly into the navigation bar and pressing Enter.
- After you get to the StillImage key, right-click on it from the left-hand side menu and click on Delete from the context menu.
Note: Don’t worry about causing any issues by deleting this key. Windows will recreate it from scratch due to the fact that the scanner driver rewrites it at the next startup.
- Close the Registry Editor and restart your computer.
In case the same problem is still occurring, move down to the next potential fix below.
Method 10: Replacing the bad USB cable
Another potential culprit is a faulty USB cable that’s connecting your computer and your scanner/printer. An old cable can turn out to be non-congruent or corroded, and this might end up affecting the transfer of data.
Since very few printer and scanner nowadays are being released with proprietary cables, try replacing it with a generic one and see if you still have the same problem. However, if the cable is proprietary, you have no other choice but to order a new one or send it for warranty.
In case this method was not applicable, move down to the final fix below.
Method 11: Changing Windows Image Acquisition (WIA) Startup Type
Another noticeable module which we found to be causing problems was the Windows Image Acquisition. This service is involved in fetching details of Windows image from official Microsoft servers. However, it is known to cause problems with other modules which includes the scanning module as well. In this solution, we will change the startup type of this service to Delayed Automatic and see if this fixes the problem.
- Press Windows + R, type “services.msc” in the dialogue box, and press Enter.
- Once in the Services tab, search for the entry of Windows Image Acquisition, right-click on it and select Properties.
- Now, change the startup type to Automatic (Delayed Start). Save changes and exit. Restart your computer and see if the problem is resolved.
