The first consumable memory stores therein first lifetime information related to a service life of the first consumable. The second consumable memory stores therein second lifetime information related to a service life of the second consumable. The controller is configured to perform: a reception process to receive an instruction to initialize the first lifetime information and the second lifetime information; an initialization process to initialize the first lifetime information and the second lifetime information; and a write process to write first initialization information indicating that the first lifetime information was initialized in the first consumable memory and to write second initialization information indicating that the second lifetime information was initialized in the second consumable memory.
