Research and Analysis of Modern Printer and Printing Defects

A printer is already crucial office equipment. However, when using any printer, it is normal to see defects in the printed contents. The research integrates the common defects that users will encounter and analyzes some feasible solutions. The paper focuses on the basic procedures of the laser printer and analyzes the common printing defects based on the procedures. After some analysis, the paper finds that most regular defects can result from malfunctioning charging units for the charging process, the laser path and its optical components, or the photosensitive drum. Afterward, the paper addressed some improvements to inhibit the defects, including enhancing craftsmanship to different units. The paper has left the common users some insights on solving the defects and has provided the manufacturers or the researchers with ideas for further improvement.
