Service action

  1. Re‑seat the imaging unit one last time and make sure it is locked into position; the blue levers should be fully pushed down and locked into position.

    Note:  This is referenced as Transfer Module in MobileTech.

  2. Replace the COLOR imaging kit since this includes the IU basket.

    Note:  No on-site service is required for this component.

  3. Should there be additional concerns or questions, contact the next level of support for further diagnosis.


This is likely a contact issue between the imaging basket and the High Volt Power Supply (HVPS).
