Replacing the EEPROM (the PU control board) with a new one clears life
information about consumables, including the belt, and toner. Note that, until
the consumables are replaced, this makes differences between their displayed
consumed and consumed lives. Such life information cleared is as shown
below. Upon replacement of the consumables, the information (counts) except
the total number of printed sheets are cleared, and differences between the
counts and consumed lives of the consumables are cleared.
