my X5150 keeps saying cartrige error see guide book 50C. I don't have the guide book. I downloaded a driver for window vista and tried to get the printer to work and now it won't even copy. I was using it as a copyer until I got my new lap top.
Same problem. I can install the program but when I try to print, there's a msg saying the printer is not connected. I've done all the trouble shooting recommended.
