Thank you for the detailed step by step procedure. Apparently, the printheads were out of date or nearing the expiration date, even tho the info panel showed "in warranty" and "OK", Some printheads had almost 1700 ml ink go thru. The weakening heads plus the aridity of our workplace adds up to drying up and failure. This is the shortest lifespan of printheads we have experienced (other printers include Roland, Encad (Kodak), Canon.
