Mdrake2016 Posted January 31 Share Posted January 31 It's crazy that after 2 years I still have these issues, and I take extreme care of these printers. I've had Cyan clogs on 3 separate P800s (half of nozzles missing on nozzle check). I searched and it seems to be a common problem with the P800 and cyan....so strange. The first 2 P800s, from the very beginning I could never get a solid blue using Cadlink (I use 1440x720 but even 1440x1440 gave me some banding on blues). The strange thing is 1 day suddenly on my second P800, it began printing a perfect solid blue. On my third P800...same thing. Banding on Cyan from the beginning. It stayed overall consistent until about a few weeks ago, then it got worse and worse 5-10 prints in before having to do a head clean. Then 1 day I was getting no Cyan at all. Here's what I've tried so far: 1. Daily - I keep it in 50% humidity. Run a headclean before every printing session. I do a headclean and manual cleaning, and also clean wiper blade and capping station every day when done printing. 2. When the cyan was completely lost, I thought it may have been the capping station. I took it apart and flushed it. Didn't work. 3. I removed the dampers, and did a flush and reverse flush with cleaner through the Cyan channel. When I put it back together, the cyan was 90% back but still banding and not a solid blue. A week later, back to running a head clean every 5-10 prints. 4. Changed the Cyan cartridge but didn't make any difference. I was told the dampers would be the problem....I seriously doubt this because again, it's Cyan on all of these printers and they were a problem from the very beginning. And flushing cleaner through the Cyan channel seemed to bring most of it back. So there seems to be just a reoccuring clog. Can anyone help me troubleshoot this?
