Abstract
A print unit, such as an inkjet printing mechanism, includes a printbar assembly that has print modules with one or more printheads that collectively span a print region corresponding to a width of a print media and deposit an imaging medium, such as ink, onto the print media. Wiper assemblies move from a print position to a service position in the print region to service the one or more printheads of the print modules. A wiper assembly has one or more wipers that correspond to the one or more printheads, such that when the wiper assembly and the print module are positioned in the service position, the wipers clean the printheads. The wiper assembly also has one or more printhead caps that cover the one or more printheads on the print modules.
