This is a report on the R2880 that started this thread. Well, today is D-day. D for decision. It's the last day I can order an R3000 and take advantage of a roughly 25% cashback. I need to decide whether to persist with the R2880 or upgrade. I'd much rather the R2880, since I can put flush carts in and hibernate it much more easily and cheaply.
It's been a long saga, and to save you all the trouble of reading it all again, here is a brief summary.
. I purchased this printer s/h at the beginning of October 2014. It appeared to be in good condition and little used, and the WIC Reset utility confirmed this. I had a good nozzle check with OEM carts
. I had a LOT of trouble initially getting fresh ConeColor inks and carts to work. My experiences are discussed in this thread. The short version is that I think the M cart was faulty, but there may also have been a little user error in filling the carts, i.e. not following the instructions to the letter. It's hard to say how much of each. I've not found other similar printers to be over sensitive about how IJM carts are are filled and reinserted.
. I eventually succeeded, but where this thread started, I had trouble keeping a good nozzle check. After a few good days I was getting gaps and bleeding. Where I got to in my last post on the R2880 on 29 Dec, a couple of carts had drained and I put the flush carts back in.
. I had strong suspicions that the PK cart was faulty and was draining. In order to test this I refilled the empty carts, gave the printer another thorough clean, and tried again.
. Surprisingly I had problems getting a good nozzle check after taking out the flush carts and reinserting the carts with ink. The PK cart was still not right, and LC had a lot of gaps. I persisted by printing purge patterns, and the occasional head clean. It never came good, and it wasn't long before I found that the PK cart had drained, again.
. I took this to be confirmation that the cart was faulty, although it was / is possible that the PK ink nozzle isn't a good fit for refillables, and I may need to use OEM in that slot.
. So another thorough printer clean, another new cart in the PK slot, and off we go again. This time I got a perfect nozzle check on all channels pretty much straight away. Fingers crossed.
. That was four days ago. The next morning I got a few similar gaps in PK (i.e. a couple of rows missing and not just random gaps) in the first nozzle check and thought oh-oh. But a closer inspection of that pattern indicated some misfiring nozzles, and the second nozzle check immediately after the first was fine. All nozzle checks since then have been ok. Well, there was a single PK nozzle in one check that was missing, but not repeated in subsequent checks.
So today I need to decide whether my problems this printer have mostly been a couple of faulty carts, or whether this printer is messing with my mind and is going to wait until 1 Feb when the cash-back has finished to recommence misbehaving, thereby demonstrating its incompatibility with refillables. At the moment, I am going to wait and cross my fingers. If it was just the faulty carts, then we need to talk offline about the four that I've had with the R2880 and R1900 being discussed in this thread, plus the issues with the R2400 being discussed in another thread.
