Abstract
A method for responding to read/write consumable volume information in an imaging device. The method includes: receiving first consumable volume information from the imaging device and storing the received first consumable volume information; receiving second consumable volume information from the imaging device; obtaining, by the imaging cartridge chip, the first consumable volume information and transmitting the first consumable volume information to the imaging device when the imaging device requests reading consumable volume information stored in the imaging cartridge chip for determining a remaining consumable volume in an cartridge; obtaining, by the cartridge chip, the second consumable volume information and transmitting the second consumable volume information to the imaging device when the imaging device requests reading consumable volume information stored in the imaging cartridge chip to indicate the remaining consumable volume in the cartridge, the second consumable volume information being less accurate than the first consumable volume information.
