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: 4 copies / original (prints/job) Ratio 30%

Environment: Normal temperature and humidity

Yield may change depending on circumstances and print conditions. Symbol keys: C: Clean, R: Replace, L: Lubricant, I: Inspect
