I have just installed a set of the new IJM carts in my R2000. Prior to the installation, I was getting good nozzle checks on flush. I had to prime the Y cart to get it running, I have done a couple of head cleans but I am getting erratic behaviour where the nozzle check is good but bad a couple of hours lately on the Y cart.
This morning, I got a good nozzle check and then decided to run a purge pattern at 720. This showed the 5 darkest carts with some banding. Do I continue with head cleans or what? Prior to this I have been using other carts that did not produce banding.
