2.14 Reading Version of Routine Replacement Units

This determines whether the parts are new or old according to the I/D of the consumable parts that
are routinely replaced, the fuser unit, and the state of the fuse in the belt unit (good/dead). If the fuse
is in a conductive state, then it is considered a new unit. A NEW or OLD decision takes place when
the power is turned ON and when the cover is closed. When the part is NEW, the life counter of the
unit is reset, and the NEW/OLD decision-making fuse in each unit is cut.
