In fact my problem is that the PGI9 Clear cartridge of the IX7000 is a bit different :
I'm hesitating between piercing the top of the cartridge with my syringe or inserting it into the ink exhaust at the bottom ?!?
Too bad, I've already purchased 1000ml of this Glop :-(
By the way, if it worked it would be quite cheaper to refill cartridges with it than buying new ones (at least in Europe).
(It comes from a german supplier : Sudhaus)
Apart of paper jam problems, what do you mean in your last paragraph ?
You suggest that using this Glop in PGI9-Clear cartridges may affect the printhead ??
