When the laser printer is running, will it produce black powder Is it harmful to the human body 5

It will not produce black powder, and the machine itself will put four colors of powder inside, which will not be harmful to the human body.

The hazards of printers are mainly as follows:

Toner, toner particles can not be melted in the human body, it is difficult to excrete, long-term inhalation or one-time inhalation of a lot of it is easy to cause respiratory diseases, and toner is a bit toxic;

Laser, the harm of laser to the human body should not be explained by me, but the general laser printer has protective measures, as long as you don't take it upon yourself to remove the cover and then print, there is no problem;

The printer is fixed by melting toner particles at high temperature, and there is a certain peculiar smell when printing, which is harmful to the human body, so you can not stand next to the printer and wait when printing, and it is best to place the printer away from the human body;

The printer circuit has a high-voltage generating circuit and a high-temperature generating circuit, so do not touch the high-temperature and high-pressure part with your hands.

Cartridge. It's not similar, but it's really going to be generated. To be precise, the toner in the toner cartridge will fly out as the printing process is used, especially if the toner produced by an irregular manufacturer is used.

In general, you don't need to worry too much about printing in small quantities, but you need to be careful when printing in large quantities. It is best to place the printer in a well-ventilated location, and also take care to keep the inside of the printer clean at all times, such as ideally vacuuming.

The jury is still out on the harm to the human body, but there is nothing wrong with being as careful as possible.

Because the laser printer needs to develop on the drum core first, and in this development process, there will be more. The printer doesn't use it as much as it actually does. So there is a scraper after rotation to remove excess developer.

Waste toner is not only toner, but also paper scraps left behind by low-quality paper.

Hazards of Waste Powder:

When there is too much waste powder, the first phenomenon of "powder leakage" will appear, that is, irregular black spots and black blocks appear on the output sample (generally longitudinally), if it is not excluded and continue to be used, after a period of time, there will be serious bottom ash (and longitudinal scratches) at the "powder leakage".

The reason for this failure is that the waste powder is piled up too much at first, so that the waste powder can not enter the waste toner bin, and the waste powder in the waste toner bin will continue to "squeeze out" and produce the phenomenon of "leakage", and then, because the waste powder contains paper ash, fibers and other dirt, it is rough, and the toner cartridge is rubbed for a long time, and it is getting tighter and tighter, and the pressure is getting bigger and bigger, and finally the photosensitive film on the surface of the toner cartridge is worn off, and the toner cartridge is damaged.

As a result, the output of the paper pattern is heavily dusted, and since they are always longitudinal friction, longitudinal scratches are visible in the bottom ash. Therefore, when the output is found to be "leaking", clean up the waste toner bin immediately.

Finally, when replacing toner, we must pay attention to cleaning up the waste toner in the waste toner collection bin, so as not to affect the output effect.

During the printing process, the toner adsorbs onto the toner cartridge, and the excess residual toner after transfer will produce what is known as waste toner.

The radiation of the laser printer is not large, and the radiance is basically the same, specific:

1. Any electrical appliance will generate electromagnetic waves during use, and the electrical appliance with the greatest radiation is not a laser printer;

2. The laser printer will only produce the relative maximum electromagnetic wave at the moment of starting and starting printing, but the radiation degree is very limited;

3. The average radiation of the laser printer is in between, only one-fifteenth of the radiation value of the mobile phone.

Therefore, the radiation of laser printers is not large, and the radiation value of each laser printer is basically the same.

The amount of radiation produced by the printer is actually very small, on average; The photocopier is slightly larger, and when in operation, the radiation dose is in between, occasionally rising to 9-10mg.

Compared with inkjet printers, the current advantages of laser printers:

1. Fast printing speed, high definition, low noise and less failure.

2. If it is black and white, the printing filament is cheap.

Similarities: Both can be printed.

Differences: The multifunction computer can not only print but also have other functions such as copying, faxing, scanning, etc., while the color laser printer can only print without other functions;

The computer has radiation, and the printer should not radiate.

Inkjet printers only emit droplets and image without dust, and if the laser cavity printing machine is old and has large static electricity, it will pollute the surrounding air to a certain extent (600x600dpi, the general toner particle size is less than 5um, except for black, the others are composed of organic pigment solids + hot melt resin after ball milling). Usually this situation only exists in the closed printing workshop next to the destruction belt, and the ventilation of the window ensures that the flow of gas fiber rubber has no impact on human health.

Laser printers are office equipment that we commonly use in our daily work, and many people think that its dust is harmful to human health. In fact, as long as it is a laser printer sold on the market, their dust hazard is almost negligible. Let's take a look at the harm of laser printers to refute rumors, laser printer dust harm rumors.

Laser printers use toner cartridges to hold toner, which is so tight that the toner inside barely flies out. During the printing process, the toner from the laser printer rarely remains on the paper, and at the same time, there is little dust flying out of the printing process. When using the printer, we should be at least half a meter away from the place where the printer outputs the paper, which can also reduce the possibility of inhaling dust.

Overall, the dust hazards of laser printers are almost non-existent, and everyone can use laser printers with confidence. Now the production technology of the printer is still very advanced, the efficiency of the laser printer to use toner is high, the machine is very durable, and it is a cost-effective office equipment. Laser printers rarely malfunction, and there are no clogged printheads, which is a great experience.

The harm of laser printers refutes rumors, and the rumors of laser printer dust hazards basically do not exist, whether they are used at home or in the office, laser printers are relatively safe.
