    PM Tables 2.1.1 OTHER 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).
