  • Page 274: Theory Of Operation

    7562 Previous Theory of operation Paper path, transport components In order for an image to be printed, the paper or specialty media has to be moved from an input source (such as Next a tray) into the printer and eventually exit into an output source. The most important component in this process is this paper itself.

  • Page 275: Transport Components

    7562 Transport components Previous The paper is fed from the tray into the printer by a pick roll and sent to two sets of feed rollers which time the paper to enter the Electrophotographic Process (EP Process) at just the right moment. The feed rollers push the paper to the transfer roll (ITU) where the image is transferred to the page.

  • Page 276: Print Engine Theory

    7562 Print engine theory Previous 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 print cartridge to the printed page. Next Even though the basic EP Process is the same for every laser and LED printer, the specifics for each printer are different.

  • Page 277: Step 1: Charge

    7562 Step 1: Charge Previous During the charge step, voltage is sent from the HVPS to the charge roller beside each of the four photoconductors. In this printer, the charge roll is part of the photoconductor unit in the print cartridges. The charge roller puts a uniform negative charge over the entire surface of the photoconductor to prepare it for Next the laser beam.

  • Page 278: Step 2: Expose

    7562 Step 2: Expose Previous During the expose step, the laser fires a focused beam of light at the surface of each photoconductor and writes an invisible image, called a latent image or electrostatic image, for each color. The laser beam only discharges the surface where the beam hits the photoconductor. This creates a difference Next in charge potential between the exposed area and the rest of the photoconductor surface.

  • Page 279: Step 3: Develop

    7562 Step 3: Develop Previous Once the laser exposes the photoconductor, the HVPS sends charge to the developer roll. For each color, the print cartridge engages the photoconductor so it is in contact with the surface. Because of the charge difference between the toner on the developer roller and the electrostatic image created by the laser, the toner is attracted to areas of the photoconductor surface exposed by the laser.

  • Page 280: Step 4A: First Transfer

    7562 Step 4a: First transfer Previous When the latent images are developed on each Photoconductor, the HVPS sends voltage to the 1st Transfer Rollers inside the ITU. The charge difference between the developed toner image on the Photoconductor surface and the 1st Transfer Next Roller causes the images to transfer to the surface of the ITU belt for each color.

  • Page 281: Step 4B: Second Transfer

    7562 Step 4b: Second transfer Previous Once the four planes of color are transferred to the transfer belt from the photoconductors, the image is carried toward the transfer roll, which is also part of the ITU. Based on the speed of the transfer belt, the proper time to send the signal to pick the paper from an input source is determined.

  • Page 282: Step 5: Fuse

    7562 Step 5: Fuse Previous Once the image has been fully transferred to the paper, the transfer roll helps move the paper into the fuser area. The fuser applies heat and pressure to the page to melt the toner particles and bond them permanently to the Next paper.

  • Page 283: Step 6: Clean/Erase

    7562 Step 6: Clean/Erase Previous 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 Next 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).
