  • Page 414: Theory Of Operation

    Theory of operation   Theory of operation POR sequence As the printer is turned on, the engine code goes through a series of tests to verify hardware integrity. If a hardware failure is detected, then it is reported to the printer. If the POR sequence cannot be completed successfully, then the printer may post an error message.
  • Page 415 Theory of operation Flowchart EP process Charge Charge roller Photoconductor drum The charge roller applies a uniform negative electrical charge to the surface of the photoconductor drum. The photoconductor drum, because of its photoconductive properties, holds the charge as long as it is not exposed to light.

  • Page 416: Service Tips

    Theory of operation Service tips • If the surface of the charge roller is damaged, such as having a nick or pit, then the charge on the photoconductor drum is uneven. A repeating mark may appear on the printed page. For more information, see Repeating defects on page •...
  • Page 417 Theory of operation Develop Auger Toner add roller Developer roller Photoconductor drum The developer roller applies the toner from the toner cartridge to the photoconductor drum. The relative opposite polarity in charge causes the toner particles to attract to the photoconductor drum areas which were exposed to light.

  • Page 418: First Transfer

    Theory of operation First transfer Photoconductor drum Transfer belt First transfer roller For each color, there is a charge difference between the developed toner image on the photoconductor drum surface and the first transfer roller. This difference causes the image to transfer to the surface of the transfer belt.

  • Page 419: Second Transfer

    Theory of operation Second transfer Second transfer roller Paper Transfer belt Fuser On the transfer belt, the four-color image is carried toward the second transfer roller until it reaches a set point. The paper pick is timed when the paper is at the exact position between the transfer belt and second transfer roller.
  • Page 420 Theory of operation Fuse Pressure roller Paper Fuser decurl rollers Heat belt Even if the toner image is already on the paper, the toner particles are not yet permanently bonded to the surface. Paper is transported from the second transfer roller to the fuser where heat and pressure are applied to it.
  • Page 421 Theory of operation Auger Cleaning blade Transfer belt When the toner image on the transfer belt is transferred to the page, the transfer belt rotates and gets cleaned by the cleaning blade. The cleaning occurs for every page that is printed.

  • Page 423 Theory of operation Second transfer roller Transfer belt Fuser roller Fuser belt Fuser decurl roller Fuser exit rollers Paper is fed from the tray or MPF into the printer by pick or feed rollers. The rollers push the paper to the transfer module where the image is transferred to the page.

  • Page 424: Printer Paper Path Sensors

    Theory of operation When the trailing edge of the media clears the fuser, the fuser engine rotates forward to prepare the fuser for the page traveling though the duplex unit. As the media reaches the gate aligner, the speed of the pick motor is adjusted to accommodate the speed of the transfer belt, ensuring the proper registration of the image on the media.

  • Page 425: Adf And Scanner Operation

    Theory of operation ADF and scanner operation Flatbed scanner drive Scanner glass area Motor (flatbed CIS scanner) Calibration reference strip ADF glass area Flatbed CIS scanner Sensor (flatbed CIS scanner) The flatbed scanner has a contact image sensor (CIS) scan module that illuminates the surface of the document.

  • Page 426: Adf Paper Path Sensors

    Theory of operation ADF feed/exit roller ADF separator roller ADF feed roller ADF pick roller ADF tray ADF bin ADF scan roller Paper from the ADF tray enters the ADF through the pick roller, feed roller, and separator roller. The back side of the paper is scanned after the paper passes the ADF feed/exit roller. The front side of the paper is scanned after the paper passes the ADF scan roller.
  • Page 427 Theory of operation Paper stop ADF pick roller ADF feed roller ADF separator roller Sensor (ADF paper present) Motor (ADF pick) The sensor (ADF paper present) detects if paper is loaded in the ADF tray. When the scan job command is signaled, the pick roller lowers to pick the paper from the ADF tray. Notes When the pick roller is raised, the leading edges of the paper in the tray are aligned by the paper stops.
  • Page 428 Theory of operation Notes If needed, calibration for the ADF CIS scanner occurs automatically before a job to adjust shading levels. During calibration, the ADF CIS scanner moves laterally to scan a reference white surface on the opposite side. The ADF CIS scanner is detected at its home position by the sensor (ADF calibration).
  • Page 429 Theory of operation ADF feed/exit roller Motor (ADF transport) Paper is fed to the ADF scan roller for front‑side scanning. At the ADF glass area, the  flatbed scanner does the scan. The ADF feed/exit roller ejects the scanned document to the ADF bin. The motor (ADF transport) drives the scan and exit rollers. The sensor (ADF scan 1) detects the paper entering the ADF glass area.
