1.What the quality of the Ink in Black (gonna print allot of documents and books), are they water prof do they clog and so on...
2.Does it leak.
3.What about the print head of the printer how much can they handle pages per month
4.What about the tubes are they silicon(from your system) or...
If you got your CISS working properly there's no leaks, no clogs, and ink not water proof that I know of.
Just print away to your hearts content with no limit to what you can print..
Cant say what the tubes are made of exactly
The tubes are high quality and the quality of the tanks is great. I don't know what inks your printer uses but the ones for my HP are excellent, the print quality is really impressive. I ordered more so I will have it on hand. I've been able to print more than I ever dreamed of, I just can't afford to replace expensive cartridges every few days. Email the seller, he will give you the straigh scoop, he is a nice guy to deal with.
