Review on Inkjet Printhead Cleaner Printer Cleaning by Michael Wiley

I have used this product with a Canon MX922 and 6821 printhead both connected. 6821 lost his pigmented black head and he cleared up quickly and easily. On the 922 All-in-One, the magenta nozzle was clogged and the black pigmented one was partially clogged. Great instructions led to clean heads the first time. The only reason I gave it 4 stars was that the "hoses" on the syringes were difficult to attach securely to the head connectors. I would buy it again. ps What is "transparency”?
