Scott Martin has posted on the Wiki about his successful use of the iPFX100 generation inks with iPFX000 printers (a Canon iPF5000 and iPF9000):
http://canonipf.wikispaces.com/message/view/FAQ/2730092Since the printers now have updated inks, but not the newer screening algorithm of the iPFX100 series printers, he has called his hybrids iPFX050 printers.
While he has successfully done the conversion with two printers, use at your own risk!
For questions or comments, please post to the Wiki Discussion forum, as Scott has requested not to get individual emails on this topic.
Thanks.
