6Activating paper
As the image is being developed, a sheet of paper is transported to the photoconductor belt. The PCL board controls this activity. A series of paper
7Transferring the image to the paper
Next, the paper contacts the surface of the photoconductor belt. Above the paper and the belt is the transfer corona, which has a high positive charge, and attracts the devel- oped image from the belt to the surface of the paper. At this point, you can remove the printed image to verify print quality, but the toner is not yet fused.
8Fusing the image to the paper
The vacuum transport unit advances the paper with the developed image to the fuser unit where heat and pressure bond the toner to the paper. The finished print then arrives at the paper output tray.
9Cleaning routine
After a print is made, the photoconductor belt must be cleaned for the next print. The belt first passes the erase lamp where any remaining latent image is erased. The belt continues to the cleaning unit where a charged brush rotates against the surface to remove any residual toner. This toner is recycled to the developer unit for reuse.
