Please Note: This will not fix faulty printheads, it is a cleaner used for removing dried particles from your print head. If your print head has a physical faul it will not repair it.
Please Note: Cleaning fluid can resolve the majority of issues however in some cases, particularly if no ink is showing on a nozzle check, the ink may be too solidified in the feed channels to the printheads for any type of cleaning fluid to break down enough and pass through. In these types of situations it is unlikely any cleaning solution will resolve the issue. Whilst cleaning fluid can be very sucessful there are situations where cleaning fluid will not resolve printhead related issues.
