I have a DCP 9020CDW with 2 broken fuser units. The first one lasted about a year. The second one lasted about 4 months. They have both failed in the same way. The heat roller has a soft black plastic like cover on it which has split and become damaged. I don't do anything unusual. I just put new paper in the tray and use refilled brother toner cartridges. I only ask, because I actually like this printer a lot. But I can't keep replacing the fuser. Nor am I likely to buy...
