Stay away. A disaster. The cartridges are recognized on the Epson BW40 after a stage in two phases (remove the old cartridge, unplug the printer and leave the free slot, plug in the printer and put the new cartridge). 3 of 4 cartridges (replacement as and extent) have not given ink at all (I have checked and yellow tape on the protective board was completely removed and I had taken care to shake the cartridge ). Result no impression and a big drop in level after 5 cleanings. (Limprimante else working fine with compatible models of the nozzles nétaient not dry when replacing cartridges).
