Abstract:
An ink jet printhead includes: a nozzle plate having an underside and including one or more nozzles in the underside configured to dispense drops of fluid in a dispensing direction; and a multi-level maintenance structure coupled to the nozzle plate such that a gap exists between a portion of the maintenance structure and the underside of the nozzle plate. The maintenance structure includes: a first portion having a first upper surface suspended at a first distance from the underside of the nozzle plate; and a second portion that is coupled to the first portion, the second portion having a second upper surface suspended at a second distance from the underside of the nozzle plate, which is greater than the first distance, the second upper surface laterally displaced relative to the first upper surface.
