Fax machines have been widely used in our work, especially between enterprises and enterprises, between enterprises and individuals, and between individuals to transmit important information, pictures, drawings, etc., all can use fax machine to complete. So, how does a fax machine send and receive faxes, and how does a fax machine work? There are so many brands of fax machines on the market, how to choose the right one? The following is an introduction to the knowledge encyclopedia of fax machines.
1 The working principle of the fax machine
1. Thermal paper fax machines (also known as roll paper fax machines): Thermal paper fax machines melt and discolor the heat-sensitive material on the print medium through a thermal print head to generate the desired text and graphics. Thermal transfer is developed from thermal technology, which transfers the ink applied on the ribbon to the paper by heating the transfer ribbon to form an image. Thermal printing is used in the most common fax machines.
2. Laser type plain paper fax machine (also known as laser all-in-one machine): A laser type plain paper fax machine is a fax machine that uses toner attached to the paper to form an image. The toner cartridge, by controlling the opening and closing of the laser beam, generates a charged image area in the toner cartridge. At this time, the toner inside the fax machine will be attracted by the charge and adhere to the paper to form text or image graphics.
3. Inkjet plain paper fax machine (also known as inkjet all-in-one machine): The working principle of inkjet fax machine is similar to that of dot matrix printing. The ink ejected from the middle is sequentially sprayed on plain paper to complete the printing work.
2 How to choose a fax machine
Speed of fax machine
If you have a lot of international business faxing, a high-speed fax machine can save you a lot of communication cost.
Determine the size of the transmission and reception of the fax machinewidth
Most fax machines transmit A4 width, but Many files cannot be transmitted due to format limitations. If you often send wide-format documents, you need to choose a B4 or even A3 fax machine.
To determine the quality requirements for file transmission
At present, the scanning density of general fax machines is mostly 7.7 lines/mm thickness, you can only transmit large Font file; if your file font is small, the other party will not be able to tell. Therefore, you should choose a 15.4 line/mm ultra-thick fax machine, which will help you solve such problems.
Determine whether to use plain paper receiving fax machines
This is an important point, since thermal paper cannot be stored for a long time, plain paper fax machines are There are obvious advantages, but its cost is relatively high.
3 How to use the fax machine
1. First, put the content to be faxed into the fax machine. Of course, the cover must be opened before this.
2. Generally, the fax machine will prompt how to place the document. The fax machine we use is with the text face down (generally the fax machine is like this).
3. Just put the content to be faxed according to the prompt, and the content to be sent is down!
4. Then it is dialing. There are two ways. Generally, the number is not recorded separately when faxing. You can dial first.
5. Then press the monitor button, which is equivalent to pressing the hands-free button of the phone. The fax machine will have an external tone, or if you don’t need an external tone, you can directly lift the phone (in fact, you can dial first. Then put the file to be transferred, but you must grasp the speed, don’t wait for the phone to be connected, the signal has been given, and the content has not been put away, it will be bad, the general recommendation is to put the fax content first! In short, just make sure to answer the phone. It’s no problem to put the documents before the call.)
6. Some fax machines are automatic. After dialing, the fax signal will be sent directly. signal, generally this signal is continuous, “di———” press the “fax/start” button at this time, the fax will be automatically transmitted, don’t worry about it!
7. There is another type of phone and fax. The number you dial is answered first. After answering the phone, tell them that you want to send a fax. Just ask her to give you a fax signal. Pay attention. It is also 7. Wait until you hear the fax signal and remember the sound of “di———“, then you can press the “fax/start button to start transmission.
8. Another dialing method It is to dial directly on the phone, that is, just like we usually make a call, pick up the receiver to dial, and then wait for the fax signal.
9. After dialing, you hear “di—–” Signal sound, press the “fax/start” button at this time, hang up the handset, the fax will be automatically transmitted, so don’t worry about it.
10. Generally, the fax speed is not very fast, please wait patiently.
11. Wait for the fax machine to spit out the contents of the fax and the fax will be sent, so that’s OK!
12. Finally, cover the cover of our fax machine. In order to prevent dust and other things from affecting the service life.
4 Fax maintenance methods
Do not turn on frequentlyTurn off
Each time the machine is turned on and off, the electronic components of the fax machine will undergo thermal changes. If it is too frequent, the thermal changes will easily lead to premature aging of the components in the machine, and the impact current of each boot will also shorten the equipment.
Use special fax paper
The recommended fax paper will be written on the manual of the fax machine. Do not use inferior quality paper for cheap. Fax paper, because inferior fax paper has insufficient finish, it will cause wear on the thermal recording head and paper feed roller.
Do not open and close the paper compartment when using it Cover
When the user is working on the fax machine, do not open the hinge cover on the paper roll. If it is really necessary, you must press the stop button to avoid danger. The action of opening or closing the paper cover should not be too violent, because most of the thermal recording heads of fax machines are installed under the paper cover. If the paper cover is closed too fast, it may cause the paper cover If it is deformed, it will cause cracking and damage to the thermal recording head.
5 Fax Machine Troubleshooting
The handwriting on one side of the document is incorrect when copyingRegulations strong>
Reason: 1. The upper cover is not fastened tightly or the hook on the side of Fan Bai is not in place.
Solution: After opening the panel, press down on both sides and re-fasten it with force
2. It may also be caused by the dislocation of the thermal head (TPH).
Processing method: After opening the panel, press the thermal head repeatedly to adjust it to reset.
Black band on document copy
Cause: The surface of the scanner (CIS) is dirty or the thermal head is faulty.
Treatment method: You can clean the scanner first, if there is still black belt, replace the thermal head.
Document copy 1/4 white
Cause: thermal head or scanner failure.
Solution: first enter the service mode, test the thermal head, and replace it if there is any problem. If the thermal head is good, the scanner is faulty, replace the scanner.
