Re: MX-M550
The ARM series had a lot of fuser issues but they fixed most of them with MXM series with adding the fuser cleaning web. What I would look at is the heat roller for toner build up, pressure roller for wrinkling, look at the sub heat roller for damage and toner buildup (make sure that cleaning felt is not loose and wrapped around the sub heat roller [a common occurrance]), look at the cleaning rollers for excessive toner buildup and finally look at the fuser cleaning web to make sure that it is turning properly and not sticking to the orange sponge roller.
I would take the following parts, as you may need them, AR620UH heat roller kit, AR620LH press roller kit, AR620HR sub heat roller kit, MX705RC web PM kit and the bearings and gear for a complete fuser rebuild. I would also bring an AR620KA kit and look at the drum side seals and toner seals to see if they need replaced.
Good luck.
