    OP-P1/MF1 Training Toner End Detection  Printer models and 3-in-1 models, except for Europe and N. America models (M145, M146, M147, M148): There is no toner end detection mechanism. The operator replaces or refills the AIO when printouts become faint or blurred.
  • Page 81 OP-P1/MF1 Training Toner End Option (1)  When the Toner End Option is set to ‘Stop Printing’:  The toner near end and toner end alert functions are enabled.  The toner near end alert will appear when toner supply runs low, and then about 50 pages can be printed until toner end.
  • Page 82 OP-P1/MF1 Training Toner End Option (2)  When the Toner End Option is set to ‘Continue Printing’:  The toner level in the AIO is not monitored.  The machine will continue printing even after toner runs out because the toner near end and toner end alerts will not appear.
  • Page 83 OP-P1/MF1 Training Toner End Option (3)  When Toner End Option is on ("Stop Printing" selected), the toner near end and toner end alerts will appear in the Error history box of the Service Mode Screen of Smart Organizing Monitor.

  • Page 85 OP-P1/MF1 Training Toner Consumption Toner Remains Rotation Time Toner Remains Progress Bar  The rate of toner consumption depends on the type of documents that are printed.  In the illustration above:  Line A shows toner consumption when documents consistently contain a large number of images that require area filling (photos, bar charts, grayscale).
  • Page 86 OP-P1/MF1 Training AIO Replacement - 1  When toner runs out, the AIO can be refilled by the service technician or the AIO can be replaced by the operator.  Refilling requires removal of two caps: the square cap to dump the toner and the round cap for refilling.
  • Page 87 OP-P1/MF1 Training AIO Replacement - 2  The ID chip on the AIO tells the machine that an AIO is installed. It is also used to detect when a new AIO is installed in the machine.  If a new AIO is detected, the toner counter is reset automatically.

  • Page 88: Refilling The Aio

    OP-P1/MF1 Training Refilling the AIO (All models except the Europe and N. America models)  The AIO is easy to refill. (Just remove caps to refill the toner and remove waste toner. There are no screws to remove.)  Drum life is the limiting factor. The AIO can be refilled 2 or 3 times (depends on use).
  • Page 89 OP-P1/MF1 Training Replacing the High-voltage Power Pack (HVPP)  There are four AIO springs but only three terminal nodes [A] (the black one doesn’t have a terminal node.)  Be sure to re-attach the black spring at the place marked with a red circle, and then the other springs with the terminal nodes in the other holes.
