Question about Office Equipment & Supplies
Posted by Anonymous on
E191 code indicates a communication error/fault has occurred between the DC Controller PCB and the HVT unit on the Composite Power Supply.
Check all of the connections for the DC Controller PCB and the Composite Power Supply.
Make sure the wire harness between the DC Controller PCB and the Composite Power Supply is good by performing continuity checks (including cross-checks and checking for a pinched wire to ground for each wire) and visually inspecting it.
Make sure the wall voltage is correct (neutral to ground should be less than 1 volt).
Finally, try replacing the DC Controller PCB and/or the Composite Power Supply.
