1. Open the bypass tray on the right side like you are removing a paper jam, leave open
2. Unplug the network wire from the back of the copier, leave unplugged.
3. Turn the machine off by the switch under a clear plastic flap; it looks like a light switch.
4. Leave the machine off for a few minutes while completing the next few steps.
5. Go to the computer where you are trying to print from, delete any files in the printer queue.
6. Restart computer.
