Laser
printing is a blessing to offices; the technology can print a lot of documents
efficiently and quickly without making a lot of noise. Moreover, the efficiency
of laser printers means that companies will save both time and manpower.
Despite the advantages brought about by laser printers, there are only a few
individuals who appreciate the intricate technology involved in the conversion
of blank paper into printed documents.
Static electricity rules laser
printing. The paper passes through a drum, which is a tube made of highly photo
conductive material that is discharged by light photons. The drum, initially
charged positive by the charge corona wire, revolves while exposed to a tiny
laser beam emitted by the printer that discharges certain points.
These points become the letters and
are coated with a positively-charged toner, which is a fine black powder. The
powder only attaches itself to the negatively-charged points of the drum.
Before the paper rolls over the drum, it is given a negative charge, so the
toner sticks to the paper. Finally, it rolls through a pair of heated rollers,
called a fuser, so that the loose toner powder melts.
After undergoing this intricate
process, your document is finished. Though printing documents with a laser
printer is relatively quick and efficient, the process is actually rather
complicated.
