Ink stabilizing material is applied to rotatable panels within a cap of an inkjet cartridge resting structure. The rotatable panels then rotate to contact an inkjet printhead when the printhead contacts the cap. Continuous periodic flushing of the printhead is performed while the rotatable panels are contacting the printhead by periodically and repeatedly alternating between ejecting a mixture of the ink stabilizing material and ink from the nozzles, and drawing the mixture of the ink stabilizing material and the ink back into the nozzles.
