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

Concept

Xerox is an outdated name for this device and partly incorrect. The device itself for making copies of text is called a copier, and when people use the term "copier", they most often mean the copier (if they are not talking 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, everyone began to use the name of the brand,when they meant the copier itself.

Working principle

Modern models of copiers 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. Light reflects off the document and forms an image on the photoconductor through a system of mirrors. In this case, positive and negative charges are formed on the surface of the drum.
3. When transferring an image onto paper, toner particles are magnetized to the drum (toward the exposed 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, due to which the toner melts and is absorbed into the paper itself.

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

Now you understand that this is a copier. The device of the unit as a whole is easy to understand: there is a scanning element in the upper part, a control panel and a display on the front, paper trays are installed at the bottom, and a tray for feeding copies made is located in the middle. Of course, different models may have different designs from each other.

Specifications

Copieris a technically complex 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 dots the copier can print on one inch (more is better). However, it is important to note that resolution cannot improve the quality of the original, but it will allow you to print a copy that is as close to it as possible.
2. Speed is the second important parameter. The higher the speed, the faster the operator can 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, very fast copiers are needed, capable of producing 30 or more copies per minute. For home use, this setting is of secondary importance.
3. Number of copies per cycle. For regular use and printing of documents on a large scale, the operator has the opportunity to set the cycle settings. The default value is 999 copies per cycle.
4. Scaling the original document is an additional functionality that could previously be present in more expensive models. Although most modern copiers currently have the function of changing the copy scale from 25 to 400%.

Functional

Specifications shown are standard. Almost every copier has them, although modern models may have more features:

1. One-or double-sided printing.
2. Automatic sheet feed.
3. Setup via PC.
4. Print from flash drive or phone.
5. Wi-Fi control.
6. Copy two-sided documents.
7. Adjust image contrast.
8. Memory unit that allows you to save certain settings.
9. Energy saving mode or automatic shutdown when not in use for a long time.

Economy

When choosing a copier, buyers pay attention to such a parameter as the price of prints per sheet. For one copier, it can be 50 kopecks, for another - 3 rubles, so this criterion is important. The fact is that refilling a copier 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 pay money for refueling each time. As a result, the cost per copy will be high.

How to use a copier?

The manufacturers of this equipment are doing everything possible to simplify the operation process for the user. They succeed. All you need to make a copy is:

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

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

Conclusion

Now you understand that this is a copier. TheThe tool combines the functions of a scanner and a printer. That is, it 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 3-in-1 technical solutions: printer, scanner, copier.
