If the part causing the problem was not supplied, use the unit including the part for replacement
Caution:
Before attempting to check the power supply, fuser unit, and the IH controller PWB, be sure to turn the power
switch off and unplug the machine from power. Allow at least 5 seconds before starting to conduct service until
the capacitors on the circuit boards have been completely discharged.
To reset a service call regarding the Maintenance T display and the DP, performing U906 Disconnection at
Defect is required. (See page 1-3-224)
