US 7,244,009 B2 · Ink jet type recording apparatus, ink type information setting method in the apparatus and ink cartridge used in the apparatus

Abstract

Ink type information is read by a read and write system (62) from a semiconductor storage system mounted on ink cartridges (9a to 9d) attached to a cartridge holder (8). A decision control system (61) decides whether or not ink type information has already been stored in ink type storage system (63), and stores the ink type information thus read when the ink type information is not stored. In the case in which the ink cartridge is exchanged, the ink type information is similarly read and it is decided whether or not the same ink type information is identical to the ink type information stored in the ink type storage system (63). If they are not identical to each other, the operation of the recording apparatus is inhibited and a display system (68) is caused to display an error message thereon.

Dependent claims

An ink cartridge holding at least ink type information indicative of an ink type of accumulated ink and ink type setting permission information for permitting a recording apparatus to set an ink type by utilizing the ink type information,

wherein the ink type information and the ink type setting permission information are provided to the recording apparatus in a state of attachment to the recording apparatus, and an ink type to be used in the recording apparatus can be set on a condition that the ink type setting permission information is obtained in the recording apparatus;
wherein the ink type information and the ink type setting permission information are stored in a semiconductor storage system mounted on the ink cartridge, and the ink type information and the ink type setting permission information can be provided to the recording apparatus in a state of attachment to the recording apparatus and
wherein the ink type setting permission information stored in the semiconductor storage system can bring a state in which the ink type setting permission information cannot be reread or the ink type setting permission information can be erased upon receipt of a command from the recording apparatus.
