Other Yield Parts; Adf (D578) - Ricoh DD 4450 Service Manual

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).
