questionable longevity

these original cartridges has a serious problem: if we do not use quite frequently the printer, you can not use any ink, because even if the printer still indicates 1/2 or 1/3 and even after Lexmark cleaning cycle, the printing is bad

and this despite they replace entire print head because it was worse before, when buying the machine

of unnecessary when buying XL if we did not intensive use in a short period.
