Xerox - what is this device? Characteristics and use of Xerox

Almost everyone knows that this is a photocopier. This is a copy machine, which is in almost every office. Its sole purpose is to make copies of documents (most often A4 standard), drawings, photographs, etc. However, few people know the basic characteristics of a photocopier, and some people even heard about it for the first time. Let's try to make out in detail what kind of device it is, how it works and how to use it correctly.

The concept

Xerox is an outdated name for this device and partly incorrect. The very device for creating copies of the text is called a copier, and when people use the term “copier”, then most often they mean a copier (if they don’t talk about Xerox).

The fact is that the first company to implement text copying technology was Xerox. And when the devices of this brand flooded the market, then everyone began to use the brand name when they had in mind the copying machine itself.

Principle of operation

Modern copier models are very different from those that Xerox produced in the sixties of the previous century. They have become more functional, faster and more compact.

The principle of operation consists of four stages:

1. A high-brightness halogen lamp illuminates the original document.
2. The light is reflected from the document and, through a system of mirrors, forms an image on the drum. In this case, positive and negative charges are formed on the surface of the drum.
3. When a picture is transferred to paper, the toner particles are magnetized to the drum (to the illuminated area) and then transferred to a blank sheet of paper.
4. After that, the sheet with the applied toner is heated to a high temperature, because of which the toner melts and is absorbed into the paper carrier itself.

The result is an exact copy of the original document. Depending on the model of the copier, 20-40 copies can be made in one minute. It’s easy to calculate how many copies you can make in an hour.

Now you understand that this is a photocopier. The unit's device as a whole is not difficult to understand: at the top there is a scanning element, on the front there is a control panel and a display, paper trays are installed at the bottom, and the tray for feeding copies is located in the middle. Of course, different models can have different designs.

Specifications

Xerox is a technically sophisticated digital device that has certain characteristics.

1. The very first and most important parameter is the print resolution, which is measured in dpi. This parameter indicates how many points the copier can print on one inch (more is better). However, it is important to note that the resolution cannot improve the quality of the original, but it will allow you to print a copy as close as possible to it.
2. Speed ​​is the second important parameter. The higher the speed, the faster the operator will be able to get the finished result. This factor plays a decisive role when it comes to choosing a copier for use on an industrial scale. For large companies, where documents are printed in huge batches, you need very fast photocopiers that can make 30 or more copies in a minute. For home use, this option is of secondary importance.
3. The number of copies per cycle. With regular use and printing of documents on a large scale, the operator has the ability to set the cycle settings. The default value is 999 copies per cycle.
4. Scaling of the source document is an additional functionality that could previously be present in more expensive models. Although most modern copiers at the moment have the function of zooming the copy from 25 to 400%.

Functional

Specified specifications are standard. Almost every copier possesses them, although modern models can have more features:

1. Single or double-sided printing.
2. Automatic sheet feed.
3. Setup via PC.
4. Print from a flash drive or phone.
5. Wi-Fi control.
6. Copy double-sided documents.
7. Adjust image contrast.
8. A memory block that allows you to save certain settings.
9. Energy-saving mode or automatic shutdown after prolonged non-use.

Cost-effectiveness

When choosing a copier, buyers pay attention to such a parameter as the price of prints of one sheet. For one copier it can be 50 kopecks, for another - 3 rubles, so this criterion is important. The fact is that Xerox refueling is a paid service. And if you choose a device with a small cartridge capacity, then you will have to refuel it quite often, and every time you pay money for refueling. As a result, the cost of one copy will be high.

How to use xerox?

The manufacturers of this technology are doing everything possible to simplify the operation process for the user. They succeed. To create a copy you only need:

1. Put paper in the special tray.
2. Attach the original document to the glass panel, cover the document with a cover.
3. Press the print button.

After a few seconds, a copy of the document will be ready. As you can see, there is nothing complicated.

Conclusion

Now you understand that this is a photocopier. This tool combines the functions of a scanner and a printer. That is, he first scans / photographs the original sample as a scanner, and then prints it as a printer.

Note that at the moment, copiers as separate devices have become obsolete. Now almost all manufacturers offer technical solutions of type 3 in 1: printer, scanner, copier.
