No one warns that installing the CISS means losing the warranty on the printer, our printer began to print poorly 2 months after purchase, as a result, the diagnosis is 200 UAH, how much repair - I do not know, they promised to call back the day before yesterday, but no one called. The warranty for the printer is an essential point, having information about the lack of warranty, I would buy a printer with a CISS installation from them, and I would buy a model with the original CISS, since there are such on the market.
