Well - to be honest if you are comfortable doing something about as complex as say - removing the head carriage cover and changing your own dampers or capping station top then installing this is simple.
Took me about 30 minutes in total. That being said - their ink train warranty
paper does require that an official dealer "certified" tech do the install. The instructions which are pretty well laid out and self explanatory does want you to flush the entire printer during the changeover which I can understand if you are running any other ink. However the instructions do want you to flush even if you are already running Triangle ink which I dont really get, nor did I do.
There are a couple of minor quirks I'm not too fond of. One being that this only uses 4 of the cartridge slots (this in itself I'm fine with) but they do not have any method to fool the printer into thinking at least those unused slots have something in them. As a result - (and the install guide even mentions this) your printer beeeeeeeps every 5 minutes complaining that 4 cartrdiges are missing - of course those 4 slots have their red lights on all the time too. Does not hurt anything or prevent printing in any way but somewhat annoying if your printer is nearby you all day. I found that I can simply stick 4 empty cartridges (does not even matter if they are full, empty, or even the right color or type of ink) in those slots though and it shuts up but this comes with a caveat. The printer could try to switch to those since it thinks they are now full and in place.
I am working on a solution for this myself though and will keep this updated with what I do.
