Yield Parts
The parts mentioned in these tables have a target yield. However, the total copy/print volume made by
the machine will not reach the target yield within the machine's targeted lifetime if the machine is used
under the target usage conditions (ACV, color ratio, P/J, and C/O). So, these parts are categorized not
as PM parts but as yield parts (EM parts). The parts with "(R)" in this table are yield parts.
Chart: A4 (LT)/5%
Mode: 2 copies / original (prints/job)
