Firstly, have you checked the manufacturer’s warning for your printer? Philips Crystal 650 – “Under very rare conditions, the ink cartridge of your device may overheat, which could damage your product and pose a potential risk of fire”.

The feedback for the download is a bit confusing – people seem to have downloaded it for use with their Crystal 660 printer and then given negative feedback because it didn’t work! Very strange. If it does work with your printer, please don’t forget to leave feedback.
