Abstract
An inkjet printing device for printing plots includes a printhead, which has a plurality of nozzles, and is capable of performing a variety of servicing functions. A method of recovering a printhead of this device includes: defining a set of causes of failures for said printhead; checking if one or more nozzles of the printhead are failing; identifying the cause of failure of a failing nozzle within said set, and, based on the identified cause of failure, performing an appropriate servicing function for recovering the failing nozzle
