These are for the C62/CX3200 printers. if you are using Genuine Epson cartridges, then yes, they are easily refillable IF you have a chip resetter.
If you use generic cartridges, the chip resetter will not work, at least I'm not aware of any compatibles that can be reset. There are indentations on the cartridges which makes the fill hole(s) easy to find.. but do not OVERFILL these or they may leak!!! Use a toothpick to determine each of the correct colour chambers, and with a bit of practice, you will learn this quickly.
can the printer still print without resetting the cartridges just like canon cli tanks? my brother just got this cx3200 and i'm trying to find out some info on it for him
No..he will need a resetter. Epson resetters are very cheap, so if the printer is still in excellent condition and will last a while, it is definitely worth refilling.
