Image forming apparatus having process cartridge, control method therefor, and storage medium
First Claim
1. An image forming apparatus having a cartridge comprised of a plurality of components, comprising:
- a memory device that stores instructions; and
at least one processor that executes the instructions to;
obtain life span information indicating respective life spans of a plurality of components of a first type cartridge, the first type cartridge being a type of cartridge on which life span information on some, but not all, of the components is obtainable;
obtain life span information indicating respective life spans of a plurality of components of a second type cartridge, the second type cartridge being a different type of cartridge than the first type cartridge, and the second type cartridge being a type of cartridge on which life span information on all of the components is obtainable;
determine whether a cartridge in the image forming apparatus is the first type cartridge;
calculate a life span of the cartridge in the image forming apparatus; and
provide notification of the calculated life span of the cartridge in the image forming apparatus,wherein, upon a condition that the cartridge in the image forming apparatus is determined to be the first type cartridge on which life span information on some, but not all, of the components is obtainable, the life span of the first type cartridge in the image forming apparatus is calculated based on only the obtained life span information on some of the components.

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.
