Title: Inkjet printing device and method of detecting abnormality of end part sensor of the same
Inventor: MURAMATSU Asuka
IPC: B41J2/01
Filed: 2020-03-30
Abstract: To provide an inkjet printing device, which is configured so that an abnormality of an end part sensor that detects a side end position of continuous paper is surely detected to prevent color drift or the like due to skewing of the continuous paper on which an image should be recorded.SOLUTION: In a recording part of an inkjet printing device, end part sensors that detect a side end position of continuous paper are provided for recording head rows corresponding to ink colors, respectively. An image position is shifted in accordance with image position correction amounts CAx(x=k, c, m and y) calculated from detected values by the sensors, so that skewing of the continuous paper can be compensated. When any of the calculated correction amounts CAx is out of a correctable range Rc, it is determined that an abnormality occurs in the end part sensor 25x (S116). Even if all of the correction amounts CAx are in the correctable range Rc, when any of in-pattern distances Dc, Dm and Dy in a JI-pattern image recorded on the continuous paper is out of an allowable range, it is determined that an abnormality has likely occurred in the sensor (S112).SELECTED DRAWING: Figure 10
