My cannon ip2770 error 6000
My Canon ip2770 all in one has started sending Error 6000 messages. I have gone through the mantenance program in the manual -(it states that the rollers will wear if done too often), and made sure that all the inks are full, no paper jammed etc. I have even tried heavy photo paper which was better, but not perfect. The rollers still clunk, and on the odd occasion when it prints, it is gappy, smudged and creased. I have also tried a new pack of paper in case the quality was inferior. But still it come out by error 6000. Can you advise please?
