Toner cartridge life is directly related to the number of rotations of the OPC. Longest
unit life is achieved with continuous printing, which requires a cleaning rotation after
every fourth page of an average-size job. Intermittent printing with small job sizes
requires a cleaning rotation after each one-page simplex job, and therefore impacts
OPC life.
A toner cartridge contains enough toner to print letter/A4-size pages at the percent
coverage stated. However, other factors also affect toner life.
