My Pro 1000 has worked flawlessly for almost two years until last week when during a photo print, I noticed significant banding in one of the photos. I ran a nozzle check and it indicates a blocked yellow channel so I initiated a head printing. This is quite a surprise since this printer performs frequent maintenance cycles to prevent such issues. One week later, during the middle of a large print job, the same issue appeared and the Yellow channel is blocked again. A manual cleaning cycle cleared the clog and the printer resumed normal operation.
This is quite strange to only have one channel clogging twice in one week so I have a feeling that channel is dying?
