Cannot Print over a TCP/IP Network (MF4890dw/MF4870dn/MF4780w Only)

Is the printer driver properly installed on your computer?
NO
Uninstall the printer driver and install it again.
YES
Is the file name of the print job too long?
YES
As a rule, LPR sends jobs under the name of the application software used for printing or the file name. A job cannot be sent to the machine if a file name exceeds 255 bytes. Use a shorter file name.
NO
Have you selected the right printer?
NO
Make sure to select the right printer to send your print jobs to. You can make your selection in the printer folder.
YES
Is the printer port of the computer properly set up?
NO
Check the printer port settings.
(1) Open the printer folder.
(2) Right-click the icon of the machine and select [Printer properties] (or [Properties]).
(3) Click the [Ports] tab.
(4) Check the settings specified for the TCP/IP printer port, the printer IP address, and name to see if the settings are configured properly in the [Print to the following port(s)] list.
If not, select the right port and press [OK].
YES
Is the TCP/IP network properly set up?
NO
Check to see if the IP address is entered correctly.
When setting the IP address through DHCP, BOOTP, or RARP, note that the DHCP, BOOTP, or RARP server needs to be running.
YES
Is the machine connected to the network successfully?
NO
Check your network settings.
YES
Are you connected with the wireless LAN?
YES
Check the following
The distance between wireless LAN router/access points is within 50 m (may vary on the communication speed or environmental condition).
There are no obstacles between the wireless LAN router/access point and the machine.
There are no microwave ovens or digital cordless phones near the installation area.
When multiple networks are used, to avoid interference between the channels, each network will be set to a channel that is as far apart from other network channels as possible such as Ch.1, Ch.6, and Ch.11.
For information on checking and setting methods for channels, refer to the instruction manual of the wireless LAN router/access point, or contact the manufacturer.
If there is no improvement:
Turn OFF the machine and wait for at least 10 seconds before turning it back ON.
