NVRAM initialization

serial number and page counts. You will also need to reconfigure any computers that print to
this printer to recognize the printer. Initialize NVRAM only when absolutely necessary. In

service menu to gather the following information:
● total page count and color page count
● fuser kit count
● serial number

until all three
lights on the control panel are lit.
