B2375dfw Mono MFP Scan Issues - System Resource not ready or Busy

I've recently encountered an error with a client's printer's scanning function:
I can no longer scan via the "Scan to PC" button on the printer. When I attempt to use this button, I receive the following error message on my computer: "The requested image could not be scanned. Please, check if your scanner is connected properly. If your system does not have enough memory, please, try to reduce the image resolution or size". On the printer's digital display, I see a message that says "System Resource not ready or busy".

That being said, the printer can scan images using Windows Fax and Scan, so the scan functionality is actually working, but the Scan to PC button is not.

Information about the setup:
- Connected to my computer via USB
- Windows 10
- Plenty of free space on computer, memory/disk space is not an issue

Things I've tried:
- Completely uninstalling and and reinstalling the printer drives and all related software
- Restarting Windows Imaging Acquisition service
- Ensuring the printer is set as the default
- Restarting the Spooler service

Although the client can currently scan via Windows Fax and Scan, he wants this issue fixed ASAP because the button on the printer is more convenient and saves him time for the large amount of scanning he has to do.

How can I fix this issue?
