The ready light (green) is on but nothing prints. Why?

• Your computer may not be properly connected to the printer. Perform the procedure described in "Connecting to the computer" in the Getting Ready guide. The interface cable may not be plugged in securely. Check both ends of the cable between the printer and the computer. Be sure to secure the connector using the wire retaining clips. Make sure you use a double-shielded, twisted-pair interface cable no more than six feet in length. The developer cartridge may be empty. To replace the cartridge, see "Replacing the developer cartridge" in your user's manual.
