Windows 10: Scanner not recognized by Win 10

I have a multifunction printer which I have been using for a couple of years. Today I tried to scan a document to file and the scanner program says" "scanner not detected on this device."

Win 10 does not recognize scanner


I hesitate to suggest this, because it's far from free ($40/$80 for standard/pro), but Vuescan has your scanner on its supported list:

VueScan Scanner Software for Windows, Mac OS X and Linux

 

Unable to get Win10 to recognize EPSON 4870 Photo Scanner


I'll walk you though the steps I do to install my Perfection 1200. I have to do this periodically for some reason to reestablish the 'non-standard' Perfection 2400 driver.

1. Right click on the scanner in Device Manager (as Admin) and select Update Driver. Then select the option to browse my computer for driver software.



2. Then select Let me pick from a list of device drivers....



3. Select Imaging Devices from the next list.



4. Finally, select the correct Epson driver you have installed then click Next. If it isn't listed then something has gone wrong with the driver installation.



5. Hopefully, the scanner should now work?

 

Win 10 does not recognize scanner


This is a very old scanner:
Microsoft Windows 2000, Microsoft Windows 95 OSR 2.1, Microsoft Windows 98/ME
Acer ScanPrisa 640U Specs - CNET

Just wondering if you really have a 64 bit driver for it?

If you only have a 32 bit driver you could use a virtualised 32 bit OS under win 10 and use it that way; other ideas suggested with 'difficult' scanners- a commercial program called Vuescan; you could also try a driver scanner program - DriverMax has found me 2 drivers I couldn't get any other way under Win 10 x64, but won't help if no 64 bit driver actually exists of course.
