Imaging Units (Drums) for Laser Printers

To work effectively, Laser printers use a photoelectric effect, like a photocopier. A drum with a special coating (The Imaging Unit) is charged with a static charge, then the image is shone onto the drum. This is done by rotating the drum and pulsing the laser. A rotating mirror moves the beam across the imaging unit and the result is a raster like system, like a TV. Where the light hits, the charge is removed. Then, the dust-like toner is transferred to the drum and where there is charge, the dust sticks. It is then transferred from the drum to paper. The last step is fusing, where a heated roller melts the toner onto the page.

Here at Office Technology Corporation we offer an extesive range of Imaging units for Lexmark and Develop machines.
