SOURCE: Drum, alarm, and data lights on--won't prnt

This unit might need resetting!

Here's how..

There's two ways to reset it

First: Soft Reset
1. Open front cover.
2. Hold down button located under LED's until all LED's are lit.
3. Release button and make sure drum LED is off, then
4. Close cover

Second: Factory Reset
1. Turn the printer off.
2. Hold in the circular button on the front panel of the printer.
3. Turn the printer back on.
4. When the DRUM light is lit by itself let go of the button.
5. Hold in the circular button on the front panel again.
6. Once the Alarm light comes on, let go of the button.
This will perform a factory reset on the printer.

I hope that's everything you want.
