Chapter 7: Fundamental Printers and Scanners 9Step 6. Fusing: In this step, the toner is permanently fused to the paper. The printingpaper is rolled between a heated roller and a pressure roller. As the paper movesthrough the heated roller and the pressure roller, the loose toner is melted andfused with the fibers in the paper. The paper is then moved to the output tray as aprinted page.The following mnemonic will help you memorize the order of the steps of the laser printingprocess:Continuous (cleaning)Care (conditioning)Will (writing)Delay (developing)Trouble (transferring)Forever (fusing)WarningThe primary corona wire or grid, or the conditioning roller, can be very dangerous. The voltage runsas high as –6000 volts. Only certified technicians should work on the unit. Before working inside alaser printer, you should make sure that the voltage is properly discharged.Describe Impact PrintersImpact printers, such as the one shown in Figure 7-3, are basic.
