  • Patent number: 10120333
    Abstract: An image forming apparatus which is capable of prompting a user to replace a process cartridge. The process cartridge is comprised of a plurality of components. At least CPU executes instructions to obtain life span information indicating life spans of the components of the process cartridge, determine whether or not the process cartridge is a specific process cartridge for which life span information on a part of the components of the process cartridge is obtained whereas life span information on all the components of the cartridge is not obtained, calculate a life span of the process cartridge, and provide notification of the calculated life span of the process cartridge. When the process cartridge is the specific process cartridge, the life span of the process cartridge is calculated based on only the obtained life span information on the components.

  • Patent number: 9522553
    Abstract: A sheet conveyance apparatus includes a convey unit, an obtaining unit, a determining unit, and a control unit. The convey unit conveys sheets. The obtaining unit obtains attribute information about sheets used in a job. The determining unit determines a first interval and a second interval. The first interval is an interval between sheets that are conveyed by the convey unit in a case where the attribute information about the sheets obtained by the obtaining unit is first attribute information. The second interval is an interval between sheets that are conveyed by the convey unit in a case where the attribute information about the sheets obtained by the obtaining unit is second attribute information that is different from the first attribute information. The control unit performs control to make the convey unit convey sheets at the interval between sheets determined by the determining unit.

  • Patent number: 9411290
    Abstract: When a toner cartridge is mounted to an image forming apparatus, if the toner cartridge is new, the image forming apparatus sets a value calculated from cartridge capacity as an initial value of a toner remaining amount. If, when the toner cartridge is mounted to the image forming apparatus, the toner cartridge is not new, the image forming apparatus sets a value calculated from a page count number as the initial value of the toner remaining amount. Furthermore, when the toner cartridge is mounted to the image forming apparatus, the image forming apparatus acquires a sensor value, and if the acquired sensor value is an indefinite value, the image forming apparatus determines an alternative value according to sensor ability as the initial value of the toner remaining amount.
