Can you post a good scan (300ppi so I can see detail) of your nozzle check for me to evaluate? Seeing your nozzle check will help me determine if it looks fixable or not.
If the mis-firing nozzles aren’t too excessive or severe, then I would suggest cleaning the capping station, wiper blade and bottom of the head following our instructions, getting a set of refill carts and PiezoFlush, and possibly also our print head cleaning kit (http://shopping.netsuite.com/s.nl/c.362672/it.A/id.6605/.f?sc=18&category=39428). You can find our recommended cleaning procedures, and a video demonstrating many cleaning procedures on a desktop model printer, here: http://www.inkjetmall.com/tech/content.php?133-Printer-Cleaning-and-Preventative-Maintenance
The R2880 is a great desktop model printer for up to 13x19 paper. We’ve had one that we’ve used for several years as our primary testing printer in our R+D labs, and that machine has been a workhorse. I have hope that you’ll be able to get yours working well after some manual cleaning, but if it turns out to be beyond repair, then the main factor to help me determine which printer(s) to recommend is, how often do you print vs. how long does the printer sit unused? If you print frequently, like at least several times a week, I would suggest getting a 3880, which can print up to 17x22 paper and has much bigger carts (less refilling, and more printing), but really- the R2880 is a great machine for smaller prints.
I hope this helps! Please keep me posted and let me know if you have further questions or there’s anything else I can help you with.
