Method for increasing printhead reliability |
摘要 |
A method of reducing intermittent weak or missing (IWM) jet failures in a phase change ink imaging device comprises fluidly connecting a positive pressure source to a print head assembly of a phase change ink imaging device. The print head assembly includes a plurality of ink jets for emitting ink drops onto an ink receiver. The method includes activating the pressure source to deliver a positive pressure pulse to the print head assembly. The pressure pulse is delivered at substantially a purge pressure. The pressure pulse has a pulse duration such that the pressure pulse bulges ink from the plurality of ink jets without emitting ink from the plurality of ink jets.
