Abstract
A method and apparatus to store information on an amount of toner used. The method includes determining whether a customer replaceable unit monitor (CRUM) memory to store information on an amount of used toner is included in a cartridge of an image forming device; storing the information on the amount of used toner in a non-volatile memory of the image forming device when the CRUM memory is not included in the cartridge of the image forming device; and storing the information on the amount of used toner in the CRUM memory when the CRUM memory is included in the cartridge.
Claims16
A method of storing information on an amount of used toner, the method comprising:
- determining whether a customer replaceable unit monitor (CRUM) memory to store information on an amount of used toner is included in a cartridge of an image forming device;
- storing the information on the amount of used toner in a non-volatile memory of the image forming device when the CRUM memory is not included in the cartridge of the image forming device;
- and
- storing the information on the amount of used toner in the CRUM memory when the CRUM memory is included in the cartridge.
A computer readable recording medium storing a program to execute a method of storing information on an amount of used toner, the method comprising:
- determining whether a CRUM memory storing the information on the amount of used toner is included in a cartridge of an image forming device;
- storing the information on the amount of used toner in a non-volatile memory of the image forming device when the CRUM memory is not included in the cartridge of the image forming device;
- and
- storing the information on the amount of used toner in the CRUM memory when the CRUM memory is included in the cartridge.
An apparatus to store information on an amount of used toner, the apparatus comprising:
- a non-volatile memory to store the information on the amount of used toner;
- a CRUM memory determination unit to determine whether a CRUM memory is included in a cartridge included in an image forming device;
- and
- a memory controller, to control the non-volatile memory to store the information on the amount of used toner when the CRUM memory determination unit determines that the CRUM memory is not included in the cartridge, and to control the CRUM memory to store the information on the amount of used toner when the CRUM memory determination unit determines that the CRUM memory is included in the cartridge.
An image forming device comprising:
- a non-volatile memory to store information on an amount of toner used;
- a CRUM memory determination unit to determine whether a CRUM memory is included in a cartridge included in the image forming device;
- and
- a memory controller, to control the non-volatile memory or the CRUM memory to store the information on the amount of used toner, according to a determination of whether the CRUM memory is included in a cartridge,
- wherein a cartridge having the CRUM memory and a cartridge having no CRUM memory are installed in the image forming device.
