CompTIA A+ Hardware Chapter 10 Review

List the seven steps used by a laser printer to print a page.

1. Processing. The print job is rendered and a bitmap of the page is created. 2. Charging. The drum is conditioned to contain a high electrical charge. 3. Exposing. A laser beam discharges the high charge down to a lower charge, but only in places where toner should go 4. Developing. Toner is placed onto the drum where the charge has been reduced. 5. Transferring. A strong electrical charge draws the toner off the drum onto the paper. 6. Fusing. Heat and pressure fuse the toner to the paper. 7. Cleaning. The drum is cleaned of any residual toner and electrical charge.

During the laser printing process, what determines when the toner sticks to the drum and when it does not stick to the drum?
