Your Windows and hardware problems solved
I recently purchased an Epson WorkForce WF-7720DTWF multifunction peripheral (MFP) to replace an ageing HP Photosmart C6280. My initial experience is that its printing and scanning are very good, but I have a problem that sours the whole experience. If I try to scan from a computer as a standard user (ie, without administrator privileges), I get a series of error messages, which is extremely inconvenient and makes it impossible to import into another program. I have a similar issue if I try to scan on the device itself and choose the computer as the destination.
As a family, we have several computers that currently run Windows 10 version 1709. The systems are set up with an admin account, but everyday work is done through standard user accounts. On any of these systems, if a user starts the Epson Scan 2 application they immediately get the error message, ‘Unable to create a work folder in the specified location. The default location will be used instead.’ If they click on the OK button they see the message ‘Connecting to the scanner’, but then there are three more of the first error messages before Scan 2 actually starts.
We see the same error message every time a setting is changed, and again when we click Preview or Scan. If I’m trying to import into PaintShop Pro I might see the error more than 20 times, and the import can fail. We never used to have any such problem with our HP Photosmart. All of the Epson software has been updated, but the only way to scan without issues is to log in as an administrator.
I’ve been in touch with Epson, whose only real advice has been for me to use an administrator account when scanning, which seems an inappropriate security risk in today’s environment. Epson also suggested that I should move the work folder to an accessible location, but didn’t tell me what it’s called or where it’s currently located.
Despite spending a lot of time searching I have been unable to find it, and besides it appears that there’s no option in the software or installer to specify an alternative location. Can you help? IM Williams
We weren’t able to re-create your issue with our test PC, which may be a good thing: given that you have the problem on all of your systems, the fact that we can’t re-create it suggests that there’s something common to all of your PCs that’s contributing to the problem. Unfortunately, working out what that is could prove challenging.
The root of the issue is almost certainly related to file permissions. Our investigations found that Epson Scan 2 creates a folder within the current user’s Temp folder called ES2WorkTemp. In your case, it seems that the software either can’t create that folder or it can’t save any files to it.
You can confirm our theory and shed a bit more light on the problem by manually exploring your Temp folder. Log in as a standard user, open an Explorer window, overwrite what’s in the address bar with
%temp% (include the % signs), then press Enter. This should bring up the contents of the currently logged-in user’s temp directory: the path will probably be C:\Users\NAME\ AppData\Local\Temp, where NAME is the user’s account name.
If, when you try to open the Temp folder, you see the message, ‘Windows can’t find C:\ Users\NAME\AppData\ Local\Temp’, navigate to C:\Users and doubleclick NAME. When prompted, click Continue and provide administrative credentials.
If Scan 2 were working normally, within the Temp folder you would see the ES2WorkTemp folder, and you would be able to open it and explore its contents. If you do see it, try right-clicking in the folder, choosing New and creating a new text file. If at any point you see the message, ‘You don’t currently have permission to access this folder’, click Continue and provide administrative credentials when prompted.
Assuming you don’t get any further error messages, try scanning again; there’s a good chance that either of the above steps will have fixed the problem.
