  • Patent number: 7869722
    Abstract: A toner dam maintenance process and system model the amount of toner mass at a toner cleaner blade, and apply a corrective procedure, such as insertion of a paperless copy into the print job mid-job or immediately prior to cycle out, to replenish the toner mass at the cleaner blade to maintain lubrication and reduce cleaning failure. The modeling includes contributing factors toward toner dam input and output, including untransferred toner, cycle-in/cycle-out bands, untransferred background, and leakage of toner from the cleaner blade. One or several threshold can be reached to cause one or more different corrective actions to take place. The action may be adding or skipping a pitch to insert a corrective maintenance pattern without transfer.
