This month I've gone through 2 packs of these cartridges on my CX6000, and I had only printed a dozen pages before the ink ran out both times. 10 of those pages were just to print test pages to realign the printer. I'm through. I'm getting rid of this craptastic printer and it's dinky cartridges and buying something more substantial. For ~$35 a set, I want a lot more than 2 good prints kthx.

I tried search ink epson cx6600 then..find 69 series box so...scroll down like "Will This Work with Your Printer?" then..i choose Epson then stylus then cx6600. result: Yes Complatible...whats hell? its waste my money for ink.

I've been using epson printers for over 15 years and I've come to rely on their printers and scanners. Buying original is always best but I do admit I sometimes buy the imitation ones and alternate it with the original. If I use mostly replacement inks, they are prone to print head blockages.

Dead On Arrival

Two of the 3 cartridges did not work when placed into the unit. The system reported they were good but when printing only on color worked. Tried everything I could think of but no good. Had ordered them as a backup so when original unit ran out I was ready. Since it had been a couple months since I ordered them, I could not return defective units when I finally plugged them into the printer.
Junk and my loss..

Update : Ordered another set. Guess what. It did not work either. After play with everything I could think of and cleaning and cleaning the heads I think there might be something wrong with the printer. Maybe I should be writing a bad review on the Epson Workforce 600 instead.

Very good ink cartridges. No problem with them. Would like for them to be a little cheaper, tho. rw
