    3.2.3 Photosensitive drum 1 Photosensitive Drum (OPC) The printed images are formed electro-photographically by the LSU and then developed on the surface of the OPC. 2 Charge Roller The charge roller creates a charge on the surface of the OPC. 3 Cleaning Blade After the image is transferred from the OPC to the media the cleaning blade scrapes any residual toner from the OPC surface into the waste toner bin.

  • Page 46: Printing Process

    3.2.4 Printing process Charging The steel shaft of the charger roller applies a high-voltage DC bias to the OPC and creates a -600V negative charge on the surface of the OPC. High voltage 1190V PCR (charge roller) -600V Exposure When the photoconductor (OPC) is exposed to the laser beam the charge on the OPC is removed. The area on the OPC that was not exposed maintains its charge, creating an image of electric potential difference.
  • Page 47 Developer The surface of developer roller adheres to a layer of charged toner by rubbing against the feed roller. After the OPC is exposed, a voltage is supplied to the developer roller (DR) when the exposed OPC contacts it. The supplied voltage is higher than the exposed area of OPC but lower than the unexposed area.
  • Page 48 Separation The printing sheet has a positive electrical charge and will be attracted to the negative charge of the OPC when it separates from the transfer roller. A serrated separation pad near the paper guide path has a ground or negative voltage that caused the sheet to separate from the OPC. A heating roller set at the designated temperature melts the toner onto the sheet when the sheet passes between it and the pressure roller.
