Good morning JMiller,
First, I am sorry to hear about your troubles with our refillable cartridges, we are here to help resolve your concerns and get to the bottom of the problem(s).
We have 3 R2880 printers that we use for testing in R&D, I keep the 2 that are not being tested on the regular stored with Piezoflush, the other that sits on my desk and gets USED for everything is not always that well maintained. We put our carts, inks and printers through the ringer, I have found the less I clean and maintain the printer, the more problems I run into. This would be the same if you never changed the oil in your car, the engine would seize up after about 30,000 miles, same applies to your printers head, capping station and wiper blade. I have found if the printer sits for more then 5 days with pigment inks it will have a very bad nozzle check and will take at least 2 head cleanings to bring it back. I find that doing a simply cleaning of the Capping station, wiper blade and bottom of the print head every 3rd time I top off the carts save me from encountering problems in the long run, saving me time and expense of a problematic printer in less then a year.
If you have [U]never[/U] cleaned your printer and you’ve been using it for 4 years with pigment inks, yes even OEM inks, then I would suspect you have a VERY clogged Capping station and VERY dirty print head and wiper blade. I would suggest the following steps be taken before refilling your cartridges and trying again. Please watch this video, follow the procedure, MINUS the Flushing attachment for the head itself, Clean the BOTTOM of the print head, the Capping station and the Wiper Blade, using ONLY bounty paper towels (they’re a safe, lint free paper towel).

Please let me know the condition of your Capping station, wiper blade and how much gunk comes off the bottom of the print head. I suspect what is happening is the Capping station is so gummed up with pigments that it is making contact withe bottom of the print head and effectively draining the cartridges while it sits. There could absolutely be a faulty cartridge, I am not ruling the out, so to play it safe I am going to send you a replacement PK & VM cartridge, I will fill them here myself to replace your lost inks and ensure they are filled correctly.
Once you are done cleaning the printer thoroughly and have received the cartridges I would appreciate it if you would drop the “faulty” carts in question in the mail for me to test. As Brian has mentioned we have had some complaints about these cartridges recently and I need to inspect for fault or damage. I will send you a prepaid label and a box for you to ship them back to us. Please let me know your results and I will get those carts in the mail today.
