    MODULE 1

    PHOTOCOPYING

    MACHINE

    What this module is about?

    Hello! We meet again my dear student! Today, we will deal about

    another kind of technology which is very useful. We will be discussing

    its definition, its history, and the different parts of it. Now, can you

    figure out that kind of technology I am referring to? Sooner you will

    find out if your guess is right.

    What you are expected to learn?

    This module is designed for you my dear student. At the end of

    the lesson, you are expected to:

    Know the definition of a photocopying machine.

    Know all about the history of a photocopying machine.

    Be familiar with the parts and uses of a photocopying

    machine.

    Identify the difference between the original documents from

    the photocopied document.

    How to learn from this module?

    You will be exploring photocopying machine sooner. Who knows

    someday you will be a businessman/ businesswoman and you choose

    to have your photocopying shop. This lesson would be a great help for

    you. Before we go further, let us now set the guidelines on how you willlearn well from this module. Learning is as simple as eating if you:

    Read the lesson wee.

    Study it very well.

    LESSON 1

    PHOTOCOPYING MACHINE

    HISTORY

    PARTS AND USES

    This module is designed in order for the students to expand their

    knowledge about the photocopying machine.

    Hi. Do you know me already? Yeah. Youre right. Im a

    photocopying machine. Its good that you already know me. How

    about my history? Oh, I expected that you did not know yet my

    history that is why you have to read those sentences below to

    know me more. I included below my definition for more

    information. Okay, take your time in reading my history.

    Photocopying machine, also called Photocopier, anydevice for producing copies of text or graphic material by

    the use of light, heat, chemicals, or electrostatic charges.

    History

    In October 1937 Chester Carlson, a patent attorney in New York,invented a process called electro photography. In 1938, this was

  • 8/8/2019 Arlene Module

    5/16

    renamed Xerography and the first known photocopy was the "10-22-38Astoria". The Xerography copying process went on to become one ofthe most well known inventions of the 20th century. Carlson receivedworld acclaim and became extremely wealthy as his invention createda billion-dollar industry. It is estimated that Carlson gave away almost

    $100 million to charity and foundations before his death in 1968.

    You already know the history and definition of a photocopying

    machine. Its about time to know more about it. The next lesson is its

    parts, and the function of its parts. Be ready my dear student, for this

    lesson requires you to familiarize yourself with its parts and uses. Look

    at the pictures and familiarize its name and function.

    Platen / Document Feeder

    The photocopier's platen is the glass

    plate on which you place the document to be copied.

    It's important to keep this clean as smudges ordebris on the platen will appear on the copy.

    Use caution when copying stapled originals asstaples can scratch the platen. Deep scratch marks willappear on every subsequent copy.

    Although the simplest, low-end copiers do not offerautomatic document feeders, most mid-range and largerones do. Document feeders mechanically rotate pagesfrom the input stack, across the platen and return them toan output stack. Some manufacturers provide specialcleaning solutions that not only clean the platen butlubricate it and reduce static as well. Lubrication and static

    reduction reduce jams in the document feeder.2. Image Capture/ lenses

  • 8/8/2019 Arlene Module

    6/16

    A lens or scanner lies below the platen. Most photocopier models

    available today are digitally based and use a scanner to capture the

    image. Historically, image capture was done by a lens and mirror, and

    some analog (lens-based) copiers are still marketed today although

    their digital counterparts are more widely available. Digital scanners

    offer more flexibility. Once the image is captured via digital

    technology, it can be stored and manipulated in addition to simply

    being replicated. This is the foundation of many multifunction devices

    that scan, copy, print and fax.

    3, Toner

    Toner is the "ink" used by the photocopier. In

    most cases, it's a powder-like component specially formulated to carry

    an electrical charge. Monochromatic photocopiers use only black tonerwhile color copiers use yellow, magenta and cyan in addition to black

    to create the full spectrum of color. Toners are contained in some type

    of cartridge and many manufactures will take back the used cartridges

    as part of their recycling efforts.

    4. Paper Input

  • 8/8/2019 Arlene Module

    7/16

    Paper is held in either a tray

    or drawer. Many mid-range and large photocopiers have

    paper drawers which hold 500 to 2,500 sheets of standard

    bond depending on the device. Heavily used copiers

    warrant larger input capacities to increase efficiency.

    Additionally, many models have various input drawers ortrays to accommodate varying sizes of paper. Standard

    photocopier paper sizes in the U.S. are letter (8.5 by 11

    inches), legal (8.5 by 14 inches) and tabloid (11 by 17

    inches).

    5. Drum

    Once the image is capture by the lens or scanner, it's inscribed

    onto a photoreceptive device called the drum. As a central component,

    the drum receives the image from the input and transfers it to the

    paper. The drum's surface is charged electro statically. The charge is

    then removed from the areas of the drum representing the image to be

    copied. Because the toner has the opposite charge, it's attracted to the

    http://www.ehow.com/legal/http://www.ehow.com/legal/
  • 8/8/2019 Arlene Module

    8/16

    negative areas on the drum surface. As the paper passed under the

    rotating drum, the toner image is transferred from the drum to the

    sheet.

    Fuser. The fuser is made up of a heat roller and a pressureroller. After the toner is transferred to the paper, the sheet

    passes between the two rollers. The combination of heat and

    pressure literally bake the toner into the sheet of paper

    making the image permanent

    7. Output device

  • 8/8/2019 Arlene Module

    9/16

    The photocopier

    output device may be a simple catch tray into which

    printed sheets fall. Many models offer optional

    finishers that collate sheets into specific order, staple

    and/or fold

    We are through with the lesson. All you have to do now is to do the

    activity and self check. These are important because the result would be the

    indicator if you really study your lesson.

    ACTIVITY 1.

    Direction: This activity is very interesting. Below are the pictures of parts of

    retake the activity.

    For the self check, if you got 9-10, very good, you study the lesson

    very very well.

    I you got 6-8, you passed the subject, and if you want you can study

    again your errors.

    If 1-5, sorry but you failed. It seems that you did not focus on our

    discussion. All you need to do now is to review this module and retake the
