  • If network printing is slow, check the network status sheet and check the signal strength. If it is poor, place your printer closer to your router or access point. Do not place your printer near a microwave oven, 2.4 GHz cordless phone, or large metal object, such as a filing cabinet.

  • If your router uses a single network name (SSID) for both the 2.4 GHz and 5 GHz band, give each band its own network name (SSID) instead, such as Home Network 2.4 GHz and Home Network 5 GHz.
  • Verify if your wireless router or access point has the Privacy Separator function enabled that prevents printing from a device through the network. See the documentation of your router or access point for instructions on disabling the Privacy Separator feature.
