Photocopiers
are one of the most essential equipments in the modern office. The photocopier has become standard
equipment, whether it is a large or small business establishment. Photocopiers allow users to
create duplicate copy of an original image or a document.
Let us look on how photocopiers work and how could an exact copy of the document or picture
be taken using a photocopier.
Photocopying Process
Plain paper photocopier works by reflecting light from the original machine so that the
image is projected onto a ‘photoreceptor’ – an electrically charged drum or belt. The drum features
a photosensitive surface and it tends to lose the electrostatic charge when it is directly exposed
to light. The reflected light generates a pattern of charges on the drum or belt and provides a
latent image. The electrostatic charge attracts the toner and regenerates the image permanently
onto the paper by pressure and heat.
Color photocopiers
Color toners were first available in the market in the 1950s. However, full color
photocopiers became popular after the release of 3M in 1968, which used a dye sublimation process
rather than the usual electrostatic technology. The first electrostatic color copier developed by
Canon hit the market in 1973.
In the last few years, it is seen that high end photocopiers have adopted digital
technology, with the copier comprising of an integrated scanner and laser printer. The latest high
end photocopiers come with several other advantages including automatic image quality enhancement
and the ability to scan pages independently for the process of printing them. Some digital
photocopiers can also function as high-speed scanners. Most of such models are backed with the
ability to send documents through email or make them available on a local area network.
While purchasing a photocopier for your business or office use, you need to consider several
features to make the selection process much easy. Some of the main points one needs to consider
while purchasing a photocopier include:
· Deciding on a digital photocopier with an ordinary one
· The size and speed of the machine
· Determining the paper delivery and capacity you need
· The type of output features required such as sorting, finishing, or stapling
· If you are planning to purchase a digital photocopier, determine whether you need to
connect it to the network or work as a standalone single unit.
A photocopier is an investment in your business or office, hence it is a better idea to
compare the features and the prices of various machines before you spend your hard earned
mone.
