Caused by :
The printer IP port is in use (ip.port_alternate or ip.port_json_config).
Steps to be taken :
- Setvar ip.port_alternate or ip.port_json_config to another value (e.g., 9101).
! U1 setvar "internal_wired.ip.port_alternate" "9101" <CR>
! U1 setvar "external_wired.ip.port_alternate" "9101" <CR>
! U1 setvar "wlan.ip.port_alternate" "9101" <CR>
! U1 setvar "ip.port_alternate" "9101" <CR>
- Setvar ip.port to the value, for example, 9100, and restart the printer.
! U1 setvar "internal_wired.ip.port" "9100" <CR>
! U1 setvar "external_wired.ip.port" "9100" <CR>
! U1 setvar "wlan.ip.port" "9100" <CR>
! U1 setvar "ip.port" "9100" <CR>
- As long as the value is not in use, you can make changes to the IP. port (internal, external, wlan).
Examples
Replace "value" with your desired IP port number.
Example 1 (For Internal Ethernet Wired)
! U1 setvar "internal_wired.ip.port_alternate" "9101"
! U1 setvar "internal_wired.ip.port" "value"
! U1 do "device.reset" ""
Example 2 (For Wireless)
! U1 setvar "wlan.ip.port_alternate" "9101"
! U1 setvar "wlan.ip.port" "value"
! U1 do "device.reset" ""
Example 3 (For External Wired Print Server)
! U1 setvar "external_wired.ip.port_alternate" "9101"
! U1 setvar "external_wired.ip.port" "value"
! U1 do "device.reset" ""
Example 4 (For printer's main IP port configurations)
! U1 setvar "ip.port_alternate" "9101"
! U1 setvar "ip.port" "value"
! U1 do "device.reset" ""
