A toner cartridge includes a customer replaceable unit monitoring (CRUM) apparatus to store error information of a toner injection process of the toner cartridge using a toner refill apparatus. Based on the error information not being stored in the CRUM apparatus, an availability of a refill operation of the toner cartridge is identified based on a predetermined first reference value and an amount of toner detected in the toner cartridge, and, based on the error information being stored in the CRUM apparatus, the availability of the refill operation of the toner cartridge is identified based on a predetermined second reference value and the amount of toner detected in the toner cartridge.

Method for error handling in the toner refill process

Provided is a method of operating an image forming apparatus. The method includes: calculating a remaining lifespan of at least one component consumed through an image forming job in the image forming apparatus; determining whether to proceed with a refill operation to refill a toner in a cartridge of the image forming apparatus, based on the remaining lifespan of the at least one component; and displaying guide information to guide the refill operation based on a result of the determining.

Image forming apparatus for guiding refilling operation of toner

An image forming apparatus is provided. The image forming apparatus includes a print engine to perform a print job by using a toner filled in a toner cartridge, a communication apparatus to communicate with a memory chip attached to a toner refill apparatus refilling the toner in the toner cartridge, and a processor to, based on an error being found in a toner injection process for the toner cartridge by using the toner refill apparatus, store information related to the error in the toner cartridge.
