  • Page 123: Theory Of Operation

    5025-2xx, 4xx Theory of operation Print engine theory Electrophotographic process (EP process) The method that all laser and LED printers use to print is called the electrophotographic process. These machines use differences in charge to manipulate and move toner from the toner cartridge to the printed page. Even though the basic EP process is the same for every laser and LED printer, the specifics for each printer are different.

  • Page 124: Step 1: Charge

    5025-2xx, 4xx Step 1: Charge During the charge step, voltage is sent from the high-voltage power supply to the charge roll inside each of the four photoconductors. The charge roll is part of the photoconductor unit. The charge rolls (A) put a uniform negative charge over the entire surface of the photoconductor to prepare it for the laser beam.

  • Page 125: Step 2: Expose

    5025-2xx, 4xx Step 2: Expose During the expose step, the laser fires a focused beam of light at the surface of each photoconductor (B) and writes an invisible image called a latent image or electrostatic image for each color. The laser beam actually discharges the surface only where the beam hits the photoconductor. This creates a difference in charge potential between the exposed area and the rest of the photoconductor surface.

  • Page 126: Step 3: Develop

    5025-2xx, 4xx Step 3: Develop Once the laser exposes the photoconductor, the high-voltage power supply sends charge to the developer roll (C). For each color, the toner cartridge engages the photoconductor so it applies toner to the surface. Because of the charge difference between the toner on the developer roll and the electrostatic image created by the laser, the toner will cling to the PC.

  • Page 127: Step 4A: First Transfer

    5025-2xx, 4xx Step 4a: First transfer When the latent images are developed on each photoconductor, the high-voltage power supply sends voltage to the first transfer rolls located in the ITU (D). The charge difference between the developed toner image on the photoconductor surface and the first transfer roll causes the images to transfer to the surface of the ITU belt for each color.

  • Page 128: Step 4B: Second Transfer

    5025-2xx, 4xx Step 4b: Second transfer Once the four planes of color are transferred to the transfer belt from the photoconductors, the image is carried towards the transfer roll (E). The transfer roll is also part of the ITU. Based on the speed of the transfer belt, the proper time to send the signal to pick the media from an input source is determined.

  • Page 129: Step 5: Fuse

    5025-2xx, 4xx Step 5: Fuse Once the image has been fully transferred to the media, the transfer roll helps move the paper into the fuser area. The fuser (F) applies heat and pressure to the page to melt the tiny toner particles and bond them permanently to the media.

  • Page 130: Step 6: Clean/Erase

    5025-2xx, 4xx Step 6: Clean/erase There are two main cleaning processes that take place during the EP process. One process cleans the transfer belt and the other cleans the photoconductors. Transfer unit clean Once the toner image on the transfer belt has been transferred to the page, the transfer belt rotates around and is cleaned by the cleaning blade (G).
  • Page 131 5025-2xx, 4xx Photoconductor clean/erase After each plane of color has been transferred to the transfer belt from the photoconductors, a cleaning blade (H) scrapes the left over toner from the surface of each photoconductor. This is the clean/erase process. Now the photoconductor surface is prepared to begin the EP cycle once again. This cleaning/erasing cycle happens after each plane of color is transferred to the transfer belt.

  • Page 132: Paper Path, Transport Components

    5025-2xx, 4xx Paper path, transport components In order for an image to be printed, the media has to be moved from an input source (such as a tray) into the printer and eventually exit into the output bin. The most important component in this process is this media itself. Old, damaged or out-of-specification media can and will cause feed and transport problems.

  • Page 133: Transport Components

    5025-2xx, 4xx Transport components In summary, the media is fed from the tray into the printer by a feed roll and carried to the transfer roll (ITU). The pick rollers time the media to enter the EP process at just the right moment. The pick rollers push the media to the ITU where the image is transferred to the page.

  • Page 134: Duplex Process

    5025-2xx, 4xx Duplex process The duplex paper path is a secondary paper path in the front cover and the 250-sheet paper tray to print on the second side of a sheet of paper. After the first side of the media is printed and the trailing edge of the paper clears the fuser exit sensor, the fuser motor reverses.

    5025-2xx, 4xx Color theory What is RGB color? Red, green, and blue light can be added together in various amounts to produce a large range of colors observed in nature. For example, red and green can be combined to create yellow. Televisions and computer monitors create colors in this manner.

    5025-2xx, 4xx My color transparencies seem dark when they are projected. Is there anything I can do to improve the color? This problem most commonly occurs when projecting transparencies with reflective overhead projectors. To obtain the highest projected color quality, transmissive overhead projectors are recommended. If a reflective projector must be used, then adjusting the Toner Darkness setting to 1, 2, or 3 will lighten the transparency.
