Abstract

The invention provides an image forming device and a method and a device for improving transfer printing characteristics of the image forming device. The method includes applying a preset idle test voltage to a transfer printing component of the image forming device by the aid of a voltage application unit of the image forming device; acquiring current values of currents transmitted through paper by the aid of an acquisition unit of the image forming device when a tip of the paper is transmitted through a clamping region between the transfer printing component and a photo-sensitive component of the image forming device; carrying out printing operation by the image forming device under the control on the basis of preset initial transfer printing bias voltage values; determining printing adjusting parameters for adjusting the initial transfer printing bias voltage values according to the current values and / or preset parameters of users; determining target transfer printing bias voltage values according to the initial transfer printing bias voltage values and the printing adjusting parameters; carrying out printing operation by the image forming device under the control on the basis of the target transfer printing bias voltage values.

Description

technical field [0001] The invention relates to the technical field of imaging control, in particular to a method, a device and an image forming device for improving the transfer characteristics of an image forming device. Background technique [0002] In the field of printing and copying technology, we know that the toner is mainly transferred from the developing unit to the latent image area of ​​the photosensitive drum under the action of electrostatic force, and then transferred from the photosensitive drum to paper such as paper. Due to the existence of impedances such as transfer rollers and paper, it has a certain impact on the electrostatic force added to the toner. Tests and experience have shown that in low temperature and low humidity environments, transfer rollers and paper have high impedance, while high impedance will result in toner It is difficult for powder to transfer to paper, and transfer defects such as white spots and mildew spots are prone to appear; u...
