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.
2.15 Life Counter of Replaceable Units
The following Table lists the life counter of the I/D, fuser unit, and belt unit that are routinely replaced
consumable parts.
2.16 Toner Usage Level Detection
The toner usage level is detected by counting the number of dots printed. The counted number of
dots is written in in IC tip in a toner cartridge.
Once toner low is detected, the toner shall be considered empty after dot counting 1,050 A4 sheets
at 5%.
However, when the power is turned back ON, and the cover is opened and closed, the printer can
still print 20 more sheets.
