LASER PRINTERS
STEP PROCESS DESCRIPTION (California Condors Won't Dance The Fandango)
1 CLEANING EP drum is cleaned with a rubber blade , and the eraser lamp (or LED's) are turned on near the surface of the EP drum, causing the drum to loose it's charge. Now the drum is ready to take on a new image
2 CONDITIONING ( CHARGING ) The EP drum is given a negative charge of approximately -600 Volts by the primary corona wire
3 WRITING ( EXPOSING ) A laser beam is used to write to the EP drum,causing the dots on the drum to loose some of the negative charge and become relatively positively charged.
4 DEVELOPING A toner is transferred from the toner cylinder to the EP drum by attracting to the area of the drum that has relative positive charge.
5 TRANSFERRING The transfer corona wire charges the paper with a high positive charge. The EP drum turns as the paper passes under It, pulling the toner into the paper. A static charge eliminator prevents the paper from wrapping around the drum.
6 FUSING The paper passes between the heated fuser roller and the rubber roller, the toner is melted and pressed into the paper. The heated roller reaches the temperature of about 180 degrees Celsius. The temperature sensor on the fuser roller will shut down the printer if the temperature gets dangerously high. Finally the excess toner is scrubbed off the paper by the cleaning pad.
