Abstract:
1. A printing apparatus comprising: a first ink tank to an n-th (n is an integer equal to or greater than 2) ink tank in which ink accommodated in an ink pack is filled; a first slot to an n-th slot that respectively correspond to the first ink tank to the n-th ink tank; a first memory unit to an n-th memory unit that are packaged together with the ink pack and are respectively installed in the first slot to the n-th slot; and a processing unit that controls read-out from or writing to the first memory unit to the n-th memory unit that are respectively installed in the first slot to the n-th slot, wherein each of the first memory unit to the n-th memory unit has a storage device, wherein the storage device stores common communication ID information that does not depend on an ink color, and ink color information corresponding to the ink color of the ink pack with which the memory unit having the storage device is packaged, and wherein the processing unit selects the j-th (j is an integer satisfying the relation of 1≦j≦n) slot from the first slot to the n-th slot, outputs a read-out command in which the communication ID information is set, to the storage device included in the j-th memory unit of the first memory unit to the n-th memory unit, which is installed in the j-th slot, determines whether ink color information that is read out based on the read-out command and an ink color corresponding to the j-th slot are consistent with each other, and determines that the j-th memory unit is erroneously installed when the read-out ink color information and the ink color corresponding to the j-th slot are inconsistent with each other.
