A fiber tracking management system controls fibers clinging to an inkjet printhead in an inkjet printing mechanism, to stop these fibers from trailing across freshly printed wet ink and leaving unsightly fiber tracks. The system includes a sled which supports a fiber crushing member that contacts the printhead when the sled is in the servicing position and crushes fibers dangling from the printhead against the printhead. The printhead carriage has a datum which extends over the printzone and collects fibers from a wiper following printhead wiping. The system also has a fiber remover which removes fibers deposited along the exterior surface of the datum. The fiber remover may be a clutch actuator or other mechanism which plucks the fibers off the carriage, or a compressible pad which smashes the fibers and scrubs ink residue from the datum. A method of controlling fibers clinging to an inkjet printhead is also provided.
