Are the network cables connected properly?
If the printer is capable of printing using another port (parallel or LocalTalk), the network or network setup may be incorrect. Check the setup and correct it if necessary. • Are the cables in good condition? Replace any worn or suspect cables with cables that you know work properly. • Does the cable-jumper setting inside the printer match the cabling that you are using? Refer to the section “Making Jumper Selections” in the manual for your Network Interface Card (NIC). In general, environments that are 10BaseT should have LINK OFF and JP1 & JP2 ON.
