Abstract
In the printing industry, electrophotography (EP) is a commonly used technology in laser printers and copiers. In the EP printing process, there are many rotating components involved in the six major steps: charging, exposure, development, transfer, fusing, and cleaning. If there is any irregularity in one of the rotating components, repetitive defects, such as isolated bands or spots, will occur on the output of the printer or copier. To troubleshoot these types of repetitive defect issues, the repeating interval of these isolated bands or spots is an important clue to locate the irregular rotating component. In our previous work, we have effectively identified the presence of isolated large pitch bands in the output from EP printers. In this paper, we describe an algorithm to estimate the repetitive interval of periodic bands, when the data is corrupted by the presence of aperiodic bands, missing periodic bands, and noise. We will also illustrate the effectiveness and robustness of our method with example results.
