Abstract: An automatic fault diagnosis method for receiving paper unit in printing press is given in this paper.The following content are included in this method：Collect the real-time image of receiving paper unit and extract the texture features of image based on Gray Level Co-occurrence Matrix；Analyze the feature and realize the automatic classifying of faults with support vector machine.

Key words: texture feature, Support Vector Machine（SVM）, printing press, fault diagnosis, image processing
