(R): 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, and P/J). 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.
