  • Make sure the IP address of this machine matches the one set on the PC.

  • Make sure the IP address does not overlap with that of other devices.

  • If [IP Address Set] is set to [Auto], the address may change dynamically. If the setting changes frequently, change [IP Address Set] of this machine to [Manual], and match the IP address of this machine with the one set on the PC.

  • Make sure the configured IP address, subnet mask and gateway address are all correct.

  • Make sure that the print port of the printer driver is correct.
