The only service calls I have had on the MPCW2200's has been for loading paper. The issue people have is the edge feeding into the printer needs to be straight and square otherwise it will fail to load. The other issue that causes this is the spools being too tight to the sides of the roll of paper.
I think this is a good machine. I would rather it had a drawer and catch trays like the black and white machines have but I am sure that would be more money and it seems like all the colors machines are like this.
