My R3000 was doing well in August 2017, but when I returned from a vacation of 3 weeks I was getting little ink out of the C channel. I tried several cleanings but was not able to improve it past about 10% of the nozzle pattern. I emailed tech support and Jon wrote back. He thought that since I was running ink that was several years old I should probably get new ink and carts. Even if I succeeded in resolving the immediate problem, I should stop running the risk of fouling the printer with deteriorating ink. Made sense.
Today, after an Amazon-like response to my order on Tuesday, I replaced all the carts and filled with new ink after cleaning the heads with the shoeshine technique, something I’ve done in the past to good effect. The C channel looks good, but now I’m getting poor output on the VM and PK channels. I’ve cleaned x3, which first got me some improvement in the VM but after the 3rd cleaning I lost that.
Since I’m having a problem with a channel that was ok, I’m wondering if I might have not properly shoeshined. I did try it again with no effect, however. What are my options at this point? Thanks.
