Apparatus and method for automatic adjustment of pre-clean corotron current |
摘要 |
Electrostatic printing machines require different types of paper with different width and thickness. In relation to the paper thickness and width is a phenomenon called the End Leakage Current Effect whereby highly positive voltage can be found in the non-paper contact area of a photoreceptor surface after the transfer stage. The paper transfer stage is when the paper touches the photoreceptor and an image is transferred onto the paper. This effect can result in cleaning failure and potential non-uniformity on the photoreceptor surface. The extent of the end leakage current effect depends on the thickness and width of the paper to which the image is being transferred. Adjusting the pre-clean corotron current based on paper thickness and width provides a remedy for the end leakage effect. Sufficient corona treatment can be provided to the residual toner to enable proper cleaning of the photoreceptor when the pre-clean corotron current is adjusted accordingly.
