AI Technical Summary

Technical Problem

When dealing with printing media of inconsistent sizes, existing image forming apparatuses have difficulty in effectively correcting severe tilting due to mechanical structure issues, resulting in offset and incomplete printed images, which affects printing quality and efficiency.

Method used

The sensor detects the offset angle of the printing medium in the paper tray and forms a transfer image with the corresponding offset angle on the transfer belt, ensuring that the angle of the transfer image is consistent with that of the printing medium, thus achieving image correction.

Benefits of technology

It effectively corrects the offset angle of the printing medium, reduces the probability of relative tilting during the printing process, improves printing quality and user experience, simplifies the operation process, and saves equipment costs.

Abstract

The application relates to the image forming field, in particular to an image correction method and device. An image correction method applied to a control component of an image forming device, comprising the following steps: determining a first offset angle of a printing medium in a paper tray; determining a second offset angle of a to-be-formed transfer image according to the first offset angle; and forming the transfer image on a transfer belt at the second offset angle. The embodiment of the application forms the transfer image with the corresponding offset angle on the transfer belt to perform printing, ensures that the normal printing of the image can be realized when the offset angle of the printing medium is large, and reduces the probability of the relative inclination between the transfer image and the printing medium.
