Why is my printer showing a 'Paper Jam' error?
Open the tray or the rear door to clear any jammed paper. Check the fuser area and duplex path. Remove all torn pieces. Close all doors and press 'Continue'.
How do I connect the printer to my network?

The imaging unit lasts approximately 60,000 pages, but this varies with usage. Replace it when you see streaks or fading on prints.
