**Please note: This chip resetter is for a very specific range of printers, they are all 10+ years old and will not work on modern printers that have similar cartridge numbers** This device is used to reset the chip on the front of Epson ink cartridges that still have at least 15% of the ink remaining. This will be necessary when refilling cartridges featuring ink monitoring chips. The Chip Resetter can be used on the following cartridges types: T007, T008, T009, T015, T016, T017, T018, T026, T027, T028, T029, T0321, T0322, T0323, T0324, T0331, T0332, T0333, T0334, T0335, T0336, T0341, T0342, T0343, T0344, T0345, T0346, T0347, T0348, T036, T037, T037, T039, T0421, T0422, T0423, T0424, T0441, T0442, T0443, T0444, T0452, T0453, T0454, T0481, T0482, T0483, T0484, T0485, T0486, T0551, T559, T0552, T0553, T0554, T0611, T0612, T0613, T0614 T0711, T0712, T0713, T0714, T0801, T0802, T0803, T0804, T0805, T0806 Once the chip has been reset your ink cartridge and printer will continue to use the amount of pages printer and the average page coverage to estimate ink levels. If there is still ink left in the cartridge when it next reads as low... you can always reset it again!You can find more information on using chip resetters here.
