It hasn't always been so easy to make copies. We now can just walk up to a photocopier
machine and press the print button and we instantly receive perfectly
replicated copies of our original. Just
forty seven years ago the copy machine was a pen and some sheets of carbon
paper. Instead of pushing a button you
had to write and write and then write some more! Just before the 60's this was a reality and
carbon paper was a big seller. Chester
Carlson, a patent attorney knew how much of a pain it was to continue rewriting
everything by hand because Carlson had arthritis. Carlson had an idea of designing a machine
that would automatically make copies, so he didn't have to do all of that copying
by hand.
Think about doing your job without a copier. You probably will have a hard time imagining
it. Did you know that most manufacturers
didn't think that a copier would be of much use? Chester tried for years to get people to
catch his vision but nobody was interested.
Between 1939 and 1944, Carlson got the thumbs down by many corporations,
including IBM, Kodak, General Electric, and RCA.
In 1937 Chester invented a process called
electro-photography. They renamed it
Xerography in 1938. He figured out that if the image of an original document
was projected onto a photoconductive surface, current would flow only in the
areas where the light shined on it. The first copy was made with a sulfur
coating on a zinc plate. He took a glass
microscope slide and wrote on it 10-22-38 ASTORIA with ink. He then pulled down the shade to darken the
room. He built up an electrostatic
charge buy rubbing the sulfur surface with a handkerchief. Then the slide was placed on the surface and
a light was shined on it for few seconds.
He then sprinkled lycopodium powder on the sulfur coating. Gently blowing on the surface, the loose
powder blew off and all that was left was the inscription, 10-22-38 ASTORIA.
10-22-38 is the date that the first photocopy was made. Astoria was the location.
The Birth of Xerox The company that decided to take a chance
on Carlson's dream was the Haloid Company.
Haloid was a photo-paper manufacturer in New York. Guess what they came to be known as? Yes, the
Xerox Corporation. In 1960 the first
office copier was produced. It was the
Xerox model 914. It was the first office
copier that could make copies on plain paper.
Being a copier repairman for over thirty-five years, I have
seen the good copiers with the bad copiers.
I began working on copiers in 1975.
The copiers that I began working with were messy and they would not last
long in between servicing. The prices
for the machines were very high especially for higher volume copiers. There were some interesting ways of
transporting the paper through the machine like the Sharp SF-740. It grabbed the paper with two gripper devices
that were driven with chains. This
machine fused the toner to the paper with a toaster oven type device.
Some people may even remember having to pour toner into the
copier from a bottle. Today's copiers have a cartridge
system that works well. They keep
most of the toner inside the copier, not on you best pair of slacks or your
dress. They have rollers for fusing the
toner to the paper and have very sophisticated paper feed and transport systems
that help reduce jamming problems.
Digital copiers are now on the market.
Now you can not only copy, but print, scan and even fax with them. Perhaps the most revolutionary change in the
industry is the full color copier. The
sales of full color copiers have really started to explode. There are a lot of new and exciting products
being introduced and the quality is really quite good. We have come a long way
from Carlson's '10-22-38 ASTORIA. I just
can't help to think what the future will bring us. What will the copier of the year 2020 look
like?

Thanks for sharing most important information about copier service, It's very helpful for those people who are using a copier. And I also need this type information. Keep giving me updates.
