Monitoring and reporting toner cartridge capacity with synthetic toner level values to provide finer granularity
An approach is provided for monitoring and reporting capacity of a toner cartridge in a printing device. The printing device determines estimated toner levels based on actual toner levels obtained from a toner sensor of the printing device. The estimated toner levels are determined based on a first actual toner level and a second actual toner level obtained from the toner senor and print usage between the two actual toner levels. The estimated toner levels are determined for levels below the second actual toner level and are mapped to synthetic toner levels. Visual indications of the synthetic toner levels are displayed on the printing device.
