A card (or passport) personalization system is described that includes a print mechanism with one or more DOD print heads. A maintenance routine, also referred to as a spitting routine, is described where one or more nozzles of the DOD print head is electrically actuated a plurality of times in rapid succession, each actuation emitting a small drop of ink. The small drops of ink join together in flight after being ejected to create one or more larger waste ink drops. The larger ink drop(s) has less tendency to aerosolize which reduces aerosol contamination of the nozzle plate and the nozzle.
