Image forming device, image forming system, and image forming method

Abstract

The invention provides an image forming device, an image forming system, and an image forming method which can prevent meandering of continuous paper when using the continuous paper for image forming. The image forming device includes an image forming unit for forming an image on continuous paper, a continuous paper conveying unit for conveying the continuous paper, and a control unit for controlling the image forming unit and the continuous paper conveying unit, wherein, after conveyance is started by the continuous paper conveying unit in printing preparation and before printing is started, the control unit is enabled to perform meandering prevention approach control of stabilizing conveyance of continuous paper that is being conveyed, and allows switching between performance and non-performance of the meandering prevention approach control and / or changing a level of the meandering prevention approach.

Description

Technical field [0001] The present invention relates to an image forming apparatus, an image forming system, and an image forming method capable of printing on continuous paper. Background technique [0002] In the case of an image forming apparatus using continuous paper, there are cases where the continuous paper skews at the start of printing and the printing result desired by the user cannot be obtained. In order to prevent the paper from snaking, the position of the edge of the paper is read by a sensor to detect the snaking (see Patent Document 1). This technology relates to a printing device for avoiding a snake-like phenomenon that may occur within a few seconds from the start of printing. Specifically, the paper edge position data is sent from the device for detecting the position of the paper edge to the meandering alarm detector, so that when meandering is detected, the progress of the paper is stopped and an alarm is displayed. Furthermore, the paper edge position d...

Problems solved by technology

[0010] However, in the technology proposed in Patent Document 1, if the meandering occurs, the device is stopped, the production efficiency is poor, and there is no means to eliminate the meandering.

[0011] In this regard, in the technique of eliminating snaking by briefly conveying paper, it is necessary to confirm that the paper is conveyed without snaking, and the work efficiency is poor.

[0012] Furthermore, in the technique proposed in Patent Document 2, it is only intended to reduce the occurrence frequency of snaking, and does not show the target method for once snaking occurs.
