  Erittäin hieno asia kun saa tälläisiä nollaus avaimia edullisesti. Paikallinen huolto ilmoitti että tulostin on romua kun mustetyyny tulee täyteen ja tulostin lopettaa toimintansa. Tutkin hieman internetin tietoja ja löysin tämän sivusaton sekä youtube videon. Homma hoitui ja tulostin tulostaa taas. Kiitos paljon!
