[edit] Guide Note

Photocopiers are electric machines that are used to make copies of documents and pictures instantaneously.

5. Can reproduce colored and/or black & white copies
6. Multifunction photocopier can also fax, scan, and print
7. Refurbished photocopiers are available for purchase or lease
8. Color photocopiers use digital laser technology
9. Some have the capability to connect to a network

A photocopier can be analog or digital. An analog photocopier will scan one page and then make copies, then scan the next page and make copies of that sheet, and so on. But a digital photocopier will first scan all the original documents once, and then reproduce several copies in a sorted and stacked fashion. An analog photocopier is less expensive than a digital photocopier.

Multifunction machines are now available due to the new digital technology. Certain models can now serve as an all-in-one machine: a photocopier, a scanner, a printer, and a fax machine. Also, some photocopiers, whether analog or digital, have all or some of the following features: stapling, folding, perform two sided copying, sorting/collating, and hole-punching. Another feature is the reduction/enlargement capability. Many of today's digital photocopiers have the ability to connect to a network through the use of an unit or an interface card.

Color photocopiers use digital laser technology, and can perform as a color printer. And through its scanning capabilities, an inkjet color printer can function as a color photocopier.

There are several factors when determining the right time to purchase a new photocopier. First one needs to consider the cost of maintaining and operating the older photocopier, and whether or not it would be cheaper to buy a newer one. Secondly, if the older photocopier is more than five years old or if the photocopier has a high volume of copies, then a changeover should be considered. As a rule of thumb, it is suggested that an older device should be replaced within four of five years after purchasing. Thirdly, one may need a replacement if the existing copier is breaking down more, has an increase in paper jams, and is in need of constant servicing, because these are obvious signs of wear-and-tear. Also, when replacing the outdated model, compare the records of its average copying volume to the photocopier’s size and speed of the new device.
