Problems solved by technology

When an ink tank is replaced, the information stored in the IC chip provided on the case of the ink tank may not match the color of the ink, etc. stored in the new ink tank
Also, the information stored on the IC chip may not indicate the correct type of actual ink cartridge
The image recording apparatus may cause an ink cartridge to be installed by mistake in a position designated for supplying ink of a different color or an improper ink cartridge to be installed in the image recording apparatus

Abstract

The present invention relates to a determination system and a printing fluid cartridge, the determination system includes a cartridge installation part, a photoelectric sensor and a controller. A printing fluid cartridge can be installed in the cartridge installation portion. The printing fluid cartridge includes a memory storing type information indicating the type of the printing fluid cartridge, and an identification portion having an inherent light transmission state different depending on the type of the printing fluid cartridge. A photoelectric sensor is provided at the cartridge mounting portion. The photosensor is configured to detect an inherent light-transmitting state of the identification portion and output a different signal depending on the detected inherent light-transmitting state. The controller is configured to perform: (a) reading type information from a memory of the printing fluid cartridge in an installed state; and (b) determining the type information of the printing fluid cartridge based on both the read type information and a signal output from the photosensor. type.

Description

technical field [0001] The present invention relates to a printing fluid cartridge and a determination system including a cartridge mounting portion in which a printing fluid cartridge is mountable. Background technique [0002] An image recording apparatus known in the art records an image on recording paper with ink. This image recording apparatus is provided with an inkjet type recording head. This image recording apparatus selectively ejects ink droplets from nozzles in a recording head toward recording paper. The ink droplets landing on the paper form a desired image on the recording paper. An ink cartridge storing ink to be supplied to a recording head is provided in this image recording apparatus. The ink cartridge is detachably mounted in a mount provided in the image recording apparatus. [0003] An integrated circuit chip (IC chip) is provided on the casing of the ink cartridge. The integrated circuit stores information related to the ink cartridge, such as th...
