Question

Network administration

EPSON L366 printer connected via WiFi. When I try to scan, I get the error "Unable to establish a connection with the scanner, make sure the scanner is on the network", everything worked fine before ... Printing works, all computers see it

Answer 1

The issue is most likely already resolved, but so be it.
1) In the folder where EPSON Scan is installed, find the escfg.exe file and run it.
2) In the window that opens, in the "Connection" item, select "On the network". The "Network Scanner Address" item appears.
3) Click "Add". In the window that opens, select "Auto Find Addresses" or "Manual Address Entry" to specify the address of your printer/scanner. When the address is specified, click "OK".
Should work for different EPSON printers. I have an EPSON XP-410.
