In this step, the printer receives the print job from the computer and interprets the data to create a bitmap image of the page. This image is stored in the printer's memory. - Processing, The printer’s drum, a cylindrical photosensitive component, is negatively charged by a corona wire or a primary charge roller to prepare it for the next step. - Charging, A laser beam selectively discharges areas of the drum to create a latent (invisible) image of the print on the drum. The areas hit by the laser have a reduced charge, corresponding to where toner will adhere. - Exposing, The toner, which is positively charged, is applied to the drum. The toner sticks to the areas of the drum that were hit by the laser (where the charge was reduced). - Developing, The toner image on the drum is transferred to the paper. The paper passes close to the drum, and a transfer roller or corona wire applies a positive charge to the paper, which attracts the negatively charged toner from the drum. - Transferring , The toner on the paper is fused to the paper fibers by applying heat and pressure. The fuser unit, consisting of a heated roller and a pressure roller, melts the toner so it sticks permanently to the paper. - Fusing, Any residual toner left on the drum is cleaned off, usually by a cleaning blade or brush, and excess toner is collected in a waste toner container. - Cleaning,
