INKJET RECORDING APPARATUS, INK TANK AND DATA COMMUNICATING SYSTEM

摘要

PROBLEM TO BE SOLVED: To avoid especially generation of an erroneous operation in a following apparatus of two-line serial communication when an ink tank of the two-line serial communication and a recording head of three-line serial communication are connected on the same communication bus. SOLUTION: A non-response command is performed (112) on either of the ink tanks (103 and 113) of the two-line serial communication on which ID is detected or the ink tanks (103 and 111) of the two-line serial communication on which no ID is detected. The performance of the non-response command is a processing that becomes non-response during a period of clock designated by a transmitting data. It is possible thereby to prevent the ink tank of the two-line serial communication connected with the same bus from generating the erroneous operation by the communication even when a communication to the recording head of the three-line serial communication is performed during the designated period after this transaction.
