What are the Different Types of Fax Machines?

A facsimile machine is a communication device that uses scanning and photoelectric conversion technology to convert still images such as documents, charts, photos, etc. into electrical signals, transmit them to the receiving end, and make copies in the form of records.

The facsimile machine passes the originals to be sent in the prescribed order.

Fax technology was born as early as the 1840s.

Common fax machines in the market can be divided into four categories: 1.

At present, there are many types of fax machines on the market, both domestically produced and imported. To purchase a fax machine suitable for your own use, you should first choose from the purpose and function. Is it for home or office use? Is the fax volume large or small? Do you want to record? Do you want plain paper? Do you want more than one and so on. Because each additional function will increase the purchase cost, you must combine your actual use situation and choose a fax machine with the best performance-price ratio.

First, the speed of the fax machine

If there are a large number of international business faxes, then high-speed fax machines can save you a lot of communication costs.

Second, determine the width of the fax machine transmission and reception

Most fax machines transmit A4 format, but many documents cannot be transmitted due to format limitations. If you often have wide document transmission, you need to choose a B4 or even A3 fax machine.

Third, determine the quality requirements for file transfer

At present, the scanning density of most fax machines is mostly 7.7 lines / mm. You can only send documents with large fonts; if your document fonts are small, the other party will not be able to distinguish them. Therefore, you should choose a 15.4 line / mm ultra-thin type fax machine, which will help you solve such problems.

Fourth, determine whether to use a facsimile machine for plain paper reception

This is very important, because thermal paper cannot be stored for a long time, so plain paper fax machines have obvious advantages, but their cost is relatively high.

The most common among the four types of fax machines are thermal paper fax machines and inkjet / laser all-in-one machines. The difference between laser all-in-one and inkjet all-in-one machines is only the printing method and the consumables used. So it can basically be divided into two camps for comparison, one is a thermal paper fax machine, and the other is an inkjet / laser integrated machine.

Thermal paper fax machines have the longest history and are cheaper. Its advantages are flexible printing.

1. Don't frequent

Development of thermal paper fax

1. Before use: Please read the instruction manual carefully and properly install the machine, including checking whether the power cord is normal and the ground is good. The machine should be protected from dust, heat,

During the use of the fax machine, maintenance is required. Due to the different structure of each model of machine, the maintenance methods are different. The following can only analyze some common failure phenomena.

1. Communication failure:

General communication failure

1. Before enabling a fax machine, you should read these safety education carefully to make better use of the fax machine in the future.

2. Do not disassemble the facsimile parts by yourself: Touching exposed electrical contacts inside the machine will cause electric shock. Take the fax to an authorized fax repairer in your area for repair.

3 The fax machine can only

Some high-end fax machines can store documents and the phone numbers of multiple recipients, and then automatically dial the phone numbers (multiple addresses) in the group and send them separately, without the user dialing the numbers one by one to send, saving a lot of dialing Time has improved office efficiency, and the results of the transmission (whether the transmission was successful) can be printed. Also called "broadcast transmission" and "multi-station transmission".

Reporting / Reference System

The fax machine is just like a person. After working for a while, you need to write a summary, report, feedback, etc., but the fax machine feedbacks some information and other fax machines.

1. When sending a fax, why does the original often appear skewed or even jammed?

When the original is in the process of transmission, either the transmission is skewed or the original is jammed, you should check in time whether the two stick shafts of the paper transmission part of the fax machine have been loosened, because once the two stick shafts are loose, there will not be enough paper If the two stick shafts are loose, the two stick shafts should be cleaned and adjusted immediately to restore the two stick shafts to their normal working conditions. If the two stick shafts are not installed in parallel, It will also easily cause the above faults, so you must ensure that the positions of the two stick axes are parallel; whether the original guide plate is placed correctly or not will also affect the transmission of the original.

Therefore, before the document is transmitted, the position of the original guide must be adjusted correctly, and the document to be transmitted is neatly placed on the guide. In addition to the above factors, the obstacles on the paper transport path are easily blocked The normal transmission of the originals results in paper jams or jams. When a paper jam occurs, everyone should remember to open the side panel cover of the fax machine in time to remove paper scraps or other obstacles on the paper transport path.

2. Why does the fax machine send multiple pages each time?

Each multi-page transfer is a very common and very common failure phenomenon. There are many possible reasons for this failure. For example, once the transmission metal sheet of the paper transfer part is deformed, this failure will occur. If the transmission metal sheet is found to be deformed, you should immediately adjust it or replace it with a new one. If the front cover of the fax machine is not properly closed, it may easily cause a multi-page transmission failure.

Therefore, before sending a fax, you should first carefully check whether the cover of the fax machine has been covered. In addition to the above two reasons, the quality of the separation rubber sheet directly affects the correct transmission of the original. If the separation rubber sheet occurs, If it is damaged or the surface is dirty, it should be replaced or cleaned with detergent.

3. Why can't the fax machine automatically input the original?

There are many factors that cause the fax machine not to automatically enter the original document. The main reasons are as follows: first, check if there is an obstacle on the paper conveying path, and if there is any, remove it immediately; second, check various related issues on the fax machine control panel. Whether the indicators work normally. If the "Fax" indicator is off, it indicates that the original position sensor or original reading sensor of the fax machine is not working properly or even malfunctions. We should check and replace them in time.

The third possible factor is that the separation rubber sheet is damaged or the pressure generated is abnormal. We should also repair it in time; the fourth reason may be the metal spring sheet and the transmission roller in the paper conveying mechanism. Loose, so that it can not generate enough pressure on the original. If so, you should check whether the side cover of the fax machine is closed, check whether the metal spring leaf has been deformed or lost its elasticity, and if it is not working properly, you should immediately replace. The fifth cause is a problem with the input part of the transmitted original. For example, if the surface of the transmitted original is too smooth, it is easy to cause slippage and the original cannot be input automatically. At this time, you should make a copy of the original and then send a copy. It is enough. If the thickness of the original is not enough, the original cannot be input automatically. Therefore, you must ensure that the thickness of the paper being transmitted is greater than 0.15 mm. Otherwise, the original cannot be curled, otherwise the fax machine will not automatically Enter the original.

The last cause of the failure is that the transfer roller of the paper transmission part is not working properly, such as slipping or falling off of the transfer belt. Once this problem is found, the belt must be reinstalled or replaced with a new belt in time. It may also be a fixed pulley The screw has become loose. If it becomes loose, quickly find a way to tighten it.
