After years of flawless operation, my IP4300 has begun to malfunction. It has begun to skip half of horizontal lines. It is difficult to describe and I wish I could upload a photo. I did a cleaning. I tried to align the heads but it keeps failing which I think is caused by my problem. I love this printer and haven't really used it much. Any suggestions? I did a test print and the printer cut off the bottom and/or the top of some of the printed lines.
