Red Bus Cartridges offer a selection of HP LaserJet Pro M401n toner cartridges including original and recycled cartridges. Recycled cartridges are recycled through our recycling factory in Lincolnshire. Then they are cleaned, repaired, refilled, tested and packaged. These are guaranteed to match the quality of an original, but at a much lower price. Red Bus Cartridges are also able to offer a free next working day delivery service as these are all dispatched from our UK factory.
