Pack 10 XL Epson (T1636) T1631-34 Superior quality ink cartridges for Epson WorkForce W WF2010 / WF2510 WF / NF WF2520 / WF2530 WF / WF2540 WF (Office Supplies)
These so-called "compatible" cartridges work on 1 dozen pages for each cartridge and the printer cartridge indicates unrecognized! So the chip in the cartridge becomes unusable while the cartridge is full, not the shot using the printer!
