    Chapter 2 Toner adheres to the electrostatic latent image on the photosensitive drum, which becomes visible. Step 3: Development Toner acquires a negative charge from the friction that occurs when the developing cylinder rotates against the developing blade. When the negatively charged toner comes in contact with the drum, it adheres to the latent image because the drum surface has a higher potential.

    If properly connected with a bi-directional interface, an external device may be used to check the printer status. When printing is executed in a Microsoft Windows or Macintosh environment, CAPT (Canon Advanced Printing Technology) serves to reduce processing speed and enhance the ease of operation to provide a user-friendly printing environment. To that end, CPU is designed for the following: — The print data from the application is turned into dot data and sent to the printer without conversion into the printer’s page description language (PDL).
