I have two 3880's: One for K7 ink and the other is dye ink for metallic and more vibrant color.
I try and run a nozzle check every week with them. I also keep them under a vinyl cover too as I'm in a very dry climate with A/C which sucks the humidity out of the air and I will get a clog if I don't run them weekly. If you live in high humidity area, it may rarely clog. I'll also pull the tanks and agitate them at least once a month, preferably twice to keep them from separating out.
I'm somewhat leery of papers over 300gsm with them. I had a very bad head strike and no doubt it caused some carriage damage. The paper used is known to have a bad edge curl and when it hit, it actually shoved the paper sideways and I suspect that broke a plastic tab in the carriage assembly (The print head's carriage is in two pieces and the inner one slides up and down via two cams to set the height off the paper.). Bad part is if one tab breaks, the head can tilt and it is then more likely to encounter another strike (and setting the head/platen distance will not matter as the head is now crooked in the inner carriage!) and do more damage. Eventually the second plastic tab broke and the head began dragging across the paper leading to a very bad mess. They sell the carriage unit out of China for $75, but it is a total pain to install. Always set Wider than you suspect (Round "up" for paper thickness distance.).
When they work they are a nice printer though. Having tore deep into mine to fix, I have a lot more respect for the designers who built it, although it is a total pain to fix when it does break.
