“… for the first time in world history, mechanical reproduction emancipates the work of art from its parasitical dependence on ritual. To an ever greater degree the work of art reproduced becomes the work of art designed for reproducibility.”Walter Benjamin
The German thinker Walter Benjamin wrote these phrases in his landmark 1935 essayThe Work of Art within the Age of Mechanical Reproduction. While Benjamin’s thesis centred on the character of artwork in a capitalist society and the consequences of mass copy – and reproducibility – on it, it’s tempting to see parallels to the impact that photocopying had on the manufacturing and availability of textual materials within the trendy period.
What is photocopying?
Broadly, photocopying is a set of strategies with which to duplicate some content material utilizing, amongst different issues, mild. However, the up to date colloquial use of the phrase ‘photocopying’ refers virtually completely to xerography.
Both the phrase ‘xerography’ and the identify ‘Xerox’ come from the Greek root-word ‘xero’, that means ‘dry’. This is as a result of xerography is a kind of photocopying methodology whose course of doesn’t contain messy liquid chemical substances. Xerographic machines are in ubiquitous use all over the world at the moment to rapidly and cheaply reproduce printed materials.
How does xerography work?
Xerography has a number of fundamental parts.
The first is the photoconductive floor – a floor coated with a photoconductive materials. Such a fabric, when uncovered to mild, permits electrons to circulate by means of it (i.e. conducts electrical energy) however blocks them when it’s darkish.
This floor is negatively charged by inserting a skinny negatively charged wire with a excessive voltage subsequent to it.
Then, the sheet of paper to be copied is illuminated with a brilliant mild. The darker components of the paper – the place one thing is printed, i.e. – don’t replicate the sunshine whereas the unmarked components do.
This mirrored mild is carried by lenses and mirrors to fall on the photoconductive floor. In the components of the floor the place mild falls, the photoconducting materials will change into conductive and permit the electrons close to its floor to dissipate downwards (right into a grounding). So the components that stay negatively charged on the finish of this step will correspond to components of the paper-to-be-copied (TBC) the place one thing was printed.
Next, a powdery substance referred to as toner is utilized to the floor. The toner is positively charged, so it will settle the place unfavourable cost persists on the floor. The floor then transfers the sample of toner on it to a sheet of paper. The paper has a stronger unfavourable cost that causes the toner to leap.
Finally, the toner is heated in order that it melts and fuses with the paper. This is the paper that rolls out of the photocopying machine, the entire course of having been accomplished in a number of seconds.
In follow, a rotating drum is used as an alternative of a flat floor, and the paper TBC is illuminated by a flashing or stroboscopic mild or a transferring scanner.
There have been many inventions because the thought of a dry photocopying method first took form within the Nineteen Thirties to enhance the xerographic course of, together with the way in which the toner is equipped, the unit value of supplies, the event of colour-copying, using lasers, and the general consumer expertise.
Who invented xerography?
Inspired by the work of the Hungarian engineer Paul Selenyi, an American legal professional named Chester F. Carlson got here up with a rudimentary model of xerography by 1938. Seven years later, he offered his thought to a non-profit organisation referred to as the Battelle Memorial Institute in Ohio, the place researchers refined the method.
A 12 months later, in 1946, the small New York-based Haloid Photographic Company bought a licence from Battelle to construct a machine based mostly on the method. The firm trademarked the identify for this machine because the “Xerox machine” in 1948 and availed the primary mannequin on the market in 1949.
(Haloid’s managers had been chargeable for coining the phrase ‘xerography’, changing Carlson’s ‘electrophotography’.)
Haloid itself modified its identify to Haloid Xerox in 1958 and to Xerox Corporation in 1961. Two explicit fashions accelerated the adoption of this know-how worldwide: the Xerox 914 in 1959, which was marketed as being quite simple to make use of, and the Xerox 813 in 1963, as with the ability to match on a desk.

In 2008, Xerox unveiled a brand new brand meant to scuttle its previous picture as a photocopier producer and spotlight its software program, color printers and different technologically up to date merchandise.

About a decade later, Xerox additionally launched the laser-based photocopier. Instead of utilizing a lamp to replicate mild off the doc to be copied to the drum, the information to be copied – or printed – was encoded as a bitmap that was fed to a laser, which then inscribed the requisite shapes onto the drum.
By the second half of the twentieth century, Xerox wasn’t the only real maker of photocopier machines, even when it was the dominant provider. Companies like Kodak made and launched units based mostly on patents they owned. Xerox remained forward as a result of its patents ensured that its rivals’ merchandise had to make use of specifically ready paper (on which to print) quite than plain paper.
IBM was in a position to overcome this when one among its researchers developed a course of based mostly on an natural photoconducting materials within the late Nineteen Sixties, amongst different adjustments.
How did xerography change the world?
Three examples illustrate xerography’s wide-ranging affect.
(i) Counterfeiting: In 2002, folks found that Xerox machines refused to repeat banknotes that included a specific marking – of 5 small rings positioned like stars within the Orion constellation. Similar markings have since been discovered on the banknotes of not less than 35 nationwide banks. A 2005 assertion from the Reserve Bank of India, accompanying the discharge of recent Rs 50 notes, referred to as it the “Omron anti-photocopying feature”, suggesting {that a} Japanese company named Omron was chargeable for designing the rings to stop counterfeiters from duplicating or printing forex notes utilizing xerographic machines.
(ii) Copyright and surveillance: In 2012, a raft of educational publishers, together with Oxford University Press, filed a go well with alleging copyright infringement towards a photocopy store and the University of Delhi. The go well with claimed that academics on the college had picked pages from books revealed by the publishers to be copied and sure collectively on the store, and offered to school college students at Rs 0.50 per web page. The matter famously concluded within the college’s favour, highlighting the rights that attend to and the advantages that accrue from with the ability to make quite a few copies of academic materials at a low value.

Similarly, Katherine Eichhorn, an affiliate professor at The New School University, New York, wrote in a 2016 e book: “the spread of copy machines made copying an increasingly independent practice … As a result, these machines enabled the reproduction of texts that would never have passed the censors,” equivalent to “militant manifestos, … DIY guides on how to build your own bombs or grow your own marijuana.”
(iii) Art: Walter Benjamin contended that by taking away the ritual of manufacturing artwork, mechanical copy had rerooted artwork’s worth in politics as an alternative. But transformative applied sciences like xerography by no means have easy penalties. As Dr. Eichhorn wrote in the identical e book, a “vibrant arts scene” that emerged in Seventies’ New York created “a generation of innovative artists, writers, and musicians” who benefited as a lot from low hire in some areas as xerography, permitting “musicians without agents” to print “homemade posters advertising upcoming gigs”, artists “to move their art out of the gallery and museum and into the street”, and writers to “self-publish zines, broadsides, and even books.”
