Abstract
A paper feeding control method for compensating the rotational speed of a paper feeding roller by varying the rotational speed appropriately according to the paper feed delay when detecting the presence of the paper feed delay on a paper feeding path of a liquid electrophotographic color printing device. The paper feeding control method measures the time taken for a paper to be fed on the paper feeding path to a certain part of the feeding path, and determines the presence and degree of the paper delayed at the certain part by comparing the measured time at the certain part with a preset paper feeding time for the certain part. Next, according to the determination made, the method adjusts the rotational speed of the driving motor for driving the paper feeding roller to increase the rotational speed of the paper feeding roller, and to compensate for the paper feed delay. Accordingly, the frequency of paper jamming occurrence due to the paper feed delay is decreased, and the paper curl occurs steadily, and also the papers are kept at uniform intervals. As a result, the deterioration of the print quality is prevented.
