I am having an issue with an Epson 9800 that I acquired. The printer had sat up for several years with minimal use. In fact the ink carts that were in there were from 2012. When I first got it I did a few power cleans and I was able to get a good nozzle check and have successfully printed with it.
However, it has been giving me intermittent nozzle clogs and never the same nozzle on the nozzle check. In fact, it would seem to get worse with the regular/auto clean cycle during the nozzle check and like I said, never the same nozzle clogged.
I have replaced the capping station, flushed all the ink lines and even removed the printhead and manually flushed it to make sure all the nozzles were spraying. When I was flushing the ink lines I noticed that I was getting some air in the lines, especially when the ink levers were raised and lowered during the initial fill and during power cleans.
After letting it sit and then inserting new carts, I did an initial fill and noticed again that small air bubbles were getting in the ink lines. The nozzle checks were again random clogs and didnt get better with auto clean. I hate to keep doing power cleans and wasting so much ink!
What would be causing this? I have not replaced the dampers. Could this be the issue? Or would it be an issue at the cartridge inlet point?
Thanks for your help!
