Count the drum rotation in a unit of [Letter
Paper Length + Paper Interval during
continuous print].
Life: When printing a distance equivalent
to 30K sheets (3P/J).
Count the number of print dots.
Determine the usage level according to
the counter value.
(Refer to 2.16)
Convert the drum rotation into [Letter
Paper Length + Distance Between Paper
Upon Continuous Printing].
One sheet of paper passing through is
counted as one on the counter.
Life: When the counter value reached 100K.
Disposal Toner Near-Full state.
If paper is longer than 13 inches, the
number of the paper sheets will be an
integer multiplied by 13 inches plus one.
Life: When counter value is 100K.
Converts the weight of discharged toner
to the number of A4 sheets and counts
the number.
Life: When the counter has reached 30K.

Stop Printing
However, 1500 sheets can be

and on again or opening/
closing the cover, the printer will
be able to print 500 more
sheets or, after 150K, 50 more
sheets.

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 50 more sheets.
