Oki Data CONFIDENTIAL
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.

The following Table lists the life counter of the I/D, fuser unit, and belt unit that are routinely re-
