[a] Estimated cartridge life means the expected or estimated toner cartridge life, which indicates the average capacity of print-outs and is designed pursuant to ISO/IEC 19752. The number of pages may be affected by operating environment, printing interval, media type, and media size. Some amount of toner may remain in the cartridge even when red LED is on and the printer stops printing.

Lenovo does not recommend using a non-genuine Lenovo toner cartridge such as one that is refilled or remanufactured. Lenovo cannot guarantee a non-genuine Lenovo toner cartridge's quality. Service or repair required as a result of using non-genuine Lenovo toner cartridges will not be covered under the machine warranty.
