Q

step 1 of the laser printing process, in which the printers raster image processing engine receives the page, font, test and graphics data from the printer drive, creates a page image and stores it in memory

processing

72
Q

step 2 of the laser printing process, in which the cylinder-shaped imaging drum receives an electrostatic charge fo 600Vdc(DC voltage) from a conditioning roller.

A

charging

73
Q

step 3 of the laser printing process, in which a moving mirror moves the laser beam across the surface of the drum. As it moves the laser beam temporarily records the image of the page to be printed on the surface of the drum by reducing the voltage of the charge applied by the charger corona to -100VDC

A

exposing

74

A

developing

75
Q

step 5 of the laser printing process: While the sheet is being fed into the printer, it receives an electrostatic charge of +600VDC from a corona wire or roller, which enables it to attract toner from the drum, which is negatively charged. As the drums surface moves close to the charged paper, the toner adhering to the drum is attracted to the electrostatically charged paper to create the printed page

A

transferring

76
Q

A

fusing

77
Q

step 7 of the laser printing process, which involves preparing the drum for a new page by removing the preceding page from the drum by using a discharge lamp. Toner that is not adhering to the surface of the drum is scraped from the drums surface for reuse.
