Tried filling two original cartridges - second fill for one of the two - seems clean as effectively as the original - recognized by the Clean & Renew system provided: - Clean the used cartridge or with alcohol - Fill with charging liquid and allow to rest before putting in the Clean & Renew - not to shake the cartridge thus filled (as it still bristles that can board in the circuit)
These precautions how many times can you refill a cartridge ??? I have not yet tested - but already with wins twice issue price compared to original cartridges
