[sane-devel] Problem with Epson Perfection V39 on Sane server on Raspberry Pi zero 2W. Please help!!

[Gaurab Dey]

Hello Everyone,

I have created a SANE server on a raspberry pi zero 2w. The server 
successfully found 2 scanners with the command sudo sane-find-scanner -q

My focus is on the Epson scanner.

found possible USB scanner (vendor=0x0bda [Realtek], product=0x8152 [USB 
10/100 LAN]) at libusb:001:004
found possible USB scanner (vendor=0x04b8 [EPSON], product=0x013d [Epson 
Perfection V39]) at libusb:001:003

scanimage --list-devices shows Both The scanners.

device `airscan:w0:HP LaserJet Pro MFP M126nw[86BC13]' is a WSD HP 
LaserJet Pro MFP M126nw[86BC13] ip=192.168.1.64
device 
`hpaio:/net/hp_laserjet_pro_mfp_m126nw?ip=192.168.1.64&queue=false' is a 
Hewlett-Packard hp_laserjet_pro_mfp_m126nw all-in-one
device `epsonscan2:Perfection V39/GT-S650:esci2:usb:ES010D:317' is a 
EPSON Perfection V39/GT-S650 flatbed scanner

Apart from sane, I have installed Epsonscan2 package.

The Epson scanner scans fine when done locally on the Raspberry Pi. But 
Not Another PDF Scanner 2 says cannot communicate with scanner when done 
from a Windows 11 computer on the network. There are 2 types of profile 
available on NAPS2, Wia does not show the Epson scanner and TWAIN option 
shows the Epson scanner. But does not work.

What can I do to scan via the Epson scanner from a Windows computer over 
the network?

What can I do to make the Epson scanner work on Windows?

Thanks in advance.
