4 4 A+ Guide to Managing and Maintaining Your PC, Fifth Edition Major Categories of Printers Impact printers Dot-matrix Non-impact printers Laser (highest quality) Inkjet Solid ink Dye-sublimation Thermal

5 5 A+ Guide to Managing and Maintaining Your PC, Fifth Edition Laser Printers

6 6 A+ Guide to Managing and Maintaining Your PC, Fifth Edition How a Laser Printer Works Places toner on electrically charged rotating drum Deposits toner on paper as paper moves through system at same speed the drum is turning

7 7 A+ Guide to Managing and Maintaining Your PC, Fifth Edition Six Steps of Laser Printing 1.Cleaning 2.Conditioning 3.Writing 4.Developing 5.Transferring 6.Fusing Take place inside toner cartridge Use components that undergo the most wear

8 8 A+ Guide to Managing and Maintaining Your PC, Fifth Edition Six Steps of Laser Printing ( continued ) 1. CleaningCleans drum of residual toner & electrical charge 2. ConditioningConditions drum to contain high electrical charge 3. WritingLaser beam discharges a lower charge to only those places where toner is to go 4. DevelopingToner is placed onto drum where the charge has been reduced 5. TransferringStrong electrical charge draws toner off drum onto paper; takes place outside the cartridge 6. FusingHeat and pressure fuse toner to paper
