I'm new to the site. i have been having a serious banding problem recently. I did a test print and it showed the magenta missing a many lines on the right side which made then do a powerful clean. i did another test print and it came out with much better results. I then printed a sample image which was 6 inches in height. the sample image was printing fine at first but for the last 2 inches banding started to occur again. I did another test print and the result was the same as the first with many magenta lines missing. Any suggestions would be greatly appreciated.
