A "harmonica chip," a technology unique to Konica Mino lta, is characterized by low heat generation, high frequency drive, and a compact multi-row structure. Based on this technology we have developed products of thin high-resolution IJ heads such as KM1024i and KM1800i.<br/> KM1024a-RC is a new product of Konica Minolta with an ink recirculation function added to the harmonica chip. The recirculating path has been designed to exhibit sufficient recirculation performance against pigment sedimentation and drying of ink, and also enables stable jetting. <br/> In this report, we introduce two recirculating paths structure for the excellent recirculation performance of the KM1024a-RC, and the evaluation results of recirculation performance and jetting performance.
