Step 1. Open the front cover of the machine where the toner cartridges are inserted. Keep this cover open until otherwise instructed.

Step 2. Ensure that the printer is turned OFF. Let it remain off for a few seconds before continuing.

Step 3. Hold the Go button down and turn the printer back on. All four LED lights should light up. When they do so, you can release the Go button. (Don’t do it before the lights come on, or you will have to start over) The LED lights should then turn off.

Step 5. Press the Go button 2 times. The LED lights for toner, drum and paper will light up and should remain on.

Step 6. Press the Go button 5 more times.

Step 7. The light for paper will be blinking. That is OK! Close the front cover and the printer should be back to normal and you can resume printing.
