    Hii,

    Try you can use the Windows app: https://apps.microsoft.com/detail/9wzdncrfj3pv?hl=en-US&gl=US

    Do the following: go to the Start menu > Settings > Bluetooth & devices > Printers & scanners > Click on the printer/scanner > click on the "Scan settings" tab > "More scan and printer settings" > select the EPSON printer > right-click and select "Start scan".

    or

    If the scanner option is missing, do the following:

    Go to Start menu > Settings > Bluetooth & devices > Printers & scanners > select a EPSON printer > Remove device

    https://www.epson.pt/pt_PT/support/sc/epson-ecotank-et-2850/s/s1953

    Access the link below, download the full driver package, and run it as an administrator.

    Try scanning and see if it works using the top feeder.

    While this is not a Microsoft website, it is the official site of [2850/EPSON].

    If Epson Scan shows the scanner as busy, the supported Windows-side actions in the available guidance are:

    1. Remove and reconnect the scanner device.
      • In Settings > Bluetooth & devices > Printers & scanners, select the Epson device and remove it.
      • Disconnect the USB cable if it is USB-connected.
      • Reconnect the device and let Windows detect it again.
      • In some cases, Windows recognizes the scanner again after reconnection.
    2. Restart the Windows Image Acquisition service.
      • Open Services.
      • Find Windows Image Acquisition (WIA).
      • Stop the service, then start it again.
      • This is a documented workaround when scanner apps cannot find or properly use a scanner after device changes.
    3. Restart the PC with the scanner connected.
      • This is another documented workaround for scanner detection and WIA-related offline/busy states.
    4. If the problem happens only in the Epson app, use a WIA-aware scanning app instead of a TWAIN-aware app.
      • A documented issue exists where 32-bit TWAIN-aware applications on 64-bit Windows can hang or fail during scanning.
      • Scanning soon after opening the scan dialog can also avoid that specific TWAIN/WIA issue.
    5. If the Epson app itself is the part failing, the application vendor must provide the fix.
      • Microsoft’s documented guidance for a “Server Busy” scan error with 32-bit scanning apps on 64-bit Windows is to contact the scanning application vendor to update the application.

    If the Epson scanner is visible in Windows but only Epson Scan reports it as busy, that points more to the Epson application layer than to Windows device detection.
