Epson Refill Ink: Epson stores the number of printed pages in a computer chip, which is located at the front of a cartridge. If we refill a cartridge, we also need to reset the page number back to zero. Otherwise, the printer will still show low ink and prevent us from printing. You have two solutions: 1) Use a chip resetter. A "resetter" tool allows us to change page number. 2) Use a refillable cartridge. Not all cartridges have resetter or refillable cartridge available. BCH keeps a web blog of current development progress for all Epson refill ink cartridges. For example, there are no solutions for T220, T288, T410, T702, T802, and T786. There are CIS solutions for T220 and partial support to T288. Check the blog for more recent progress.
