Query: Paper Eater

I purchased the BJC-6000 because I loved my BJC-620 my wife took over after she got her own computer. I like the idea of seperate ink cartridges that can be replaced individualy. However, my BJC-6000 has been in the shop 3 times because of constant paper jamming. The machine would not accecpt the paper correctly every time, and when it did take, it came out crooked. The 2nd time it went in, they corrected the problem which lasted about 3 weeks. Then, one day, it snatched in a page and managed to crumple it up and damage the print head in the process. Ink all over the interior resulted in replacement of the platten. Insult to injury was added on when I was charged for a new print head even though the machine was still under warranty. I may have purchased a lemon. I am dissapointed in the BJC-6000, especially after I had good results with the BJC-620.
