    Theory of operation   Theory of operation POR sequence As the printer turns 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 427: Charge

    Theory of operation Charge Charge roller Photoconductor drum The charge roller applies a uniform negative electrical charge to the surface of the photoconductor drum. The photoconductive properties of the surface material allow it to hold the charge as long as it is not exposed to light.

  • Page 428: Expose

    Theory of operation Expose Printhead Photoconductor drum The printhead emits the light that contacts the surface of the photoconductor drum. The light turns on or off coinciding with the digital latent image. The light causes areas of the photoconductor drum surface to lose charge, resulting in a relative opposite polarity.

  • Page 429: Develop

    Theory of operation Develop Toner cartridge Developer roller Photoconductor drum The developer unit applies the toner from the toner cartridge to the photoconductor drum. The difference in charge causes the toner particles to attract to the photoconductor drum areas which are exposed to light.

  • Page 430: Transfer

    Theory of operation Transfer Charge roller Transfer roller Paper The transfer roller applies a positive charge to the paper, which is pressed between the transfer roller and the photoconductor drum. Due to relative opposite polarities between the paper from the transfer roller, and the photoconductor drum from the charge roller, the charge attracts the toner to the paper.

  • Page 431: Fuse

    Theory of operation Fuse Fuser Paper Even if the toner image is already on the paper, the toner particles are not yet permanently bonded to the surface. For the final part of printing, the paper is transported to the fuser where heat and pressure are applied to it.

  • Page 433: Printer Paper Path

    Theory of operation Printer paper path Simplex print job Paper exit roller Fuser exit roller Fuser Photoconductor drum Deskew roller Transport roller Feed roller Pick roller Transfer roller The pick and feed rollers pick the paper, and then feeds it to the transport roller. The transport roller moves the paper to the deskew roller where the paper skew is corrected.

  • Page 434: Duplex Print Job

    Theory of operation The deskew roller feeds the paper to the transfer roller for image transfer. At the transfer roller, the photoconductor drum transfers the developed image to the paper to create the printed image. As the paper passes the fuser, heat and pressure are applied to bond permanently the toner to the paper.

  • Page 438: Adf Paper Path

    Theory of operation The flatbed scanner has a scanner lamp that illuminates the surface of the document. The reflections produced are processed to create the scan image. For flatbed scan jobs, the flatbed scanner moves across the scanner glass area to scan the front side of the document.

  • Page 439: Adf Paper Path Sensors

    Theory of operation The scan rollers continue to move the paper to the scan area until the trailing edge of the paper reaches the sensor (ADF scan). When the trailing edge of the paper reaches the sensor (ADF scan), the sensor goes to the off position. Scanning continues for a predetermined length of time.
