After my last set of issues with R2000 carts, I had my printer sitting with flush carts. When I started it again, it all looked good. I thought that it may be advisable to start recording my daily nozzle check in case of any future issues. It didn’t take long. I got four days before the problems started. For the next to days, the PK cart was missing a few segments which were cleared by another nozzle check. Today, the nozzle check showed about two full lines missing on the R cart. I ran another nozzle check and then had 2 lines missing in R and PK. I ran an inksep which gave a nice big blob on the paper but a subsequent nozzle check was clear.
I pulled the carts to see if there is any obvious draining. If there is, it must be slow. As you know, I have already replaced two defective carts and now I have at least one more. I bought a number of sets of these carts when I bought my R2000 but I’m now wondering whether there is a good set in the lot of them.
I would not have thought that I was asking for anything unusual when I bought these carts. My belief is that they are defective to start, and certainly more problematic than they should be. What am I supposed to do now? Should I keep on trying different carts in the hope that I may actually get a reliable set?
