Electrostatic charge is the relatively static and negative charge that is generated on the surface of an object caused by friction between different objects. For any electronic product, static electricity is a natural enemy. Large format printers, as a precision mechanical device, are particularly vulnerable to static electricity. The generation of static electricity will not only affect the print quality, cause damage to the printer, but also have a certain impact on human health. Therefore, preventing and eliminating static electricity is a necessary task for large-format printer users.
How is static electricity generated during the application of large format printers? From a macroscopic point of view, static electricity is generated by the contact, friction and separation between objects, and the air drying in the work shop. As far as the printing environment is concerned, under the same conditions, the lower the humidity, the drier the air, and the higher the electrostatic voltage, the more it will affect the normal operation of the printer. Experiments show that when the relative humidity of the equipment room is 30%, the static voltage is 5000V; when the relative humidity drops to 5%, the static voltage will reach 20000V. In terms of large format printers, in addition to environmental factors, the part of the machine where the center shaft is in contact with the paper is the area where static electricity is most likely to occur. In particular, paper that has not been treated with static electricity, such as some plastic substrates that are relatively inexpensive on the market Pp photographic paper, because the non-conductive plastic is strong, it is more likely to produce static electricity, and will appear the adsorption phenomenon with the constant friction.
The effects of static electricity on the output of large format printers, machine wear, and human health are obvious. In general, static electricity easily interferes with electronic circuits and causes instantaneous changes in potential. Electrostatic discharge can cause malfunctions in electronic devices, breakdown of integrated circuits and sophisticated electronic components, and aging of components. At the same time, static electricity can affect the mind and body of operators. Health causes psychological pressure on operators and decreases work efficiency. Moreover, severe static electricity can burn the device's motherboard and circuit, causing damage to the printer; it also affects the print quality, attracts ink droplets during the printing process, and causes ink leakage in the printer; it also absorbs dust and binds the paper and affects printing. .
Therefore, preventing and eliminating static electricity is an important task for large-format printer users. To ensure the security of large format printers and computer rooms is a prerequisite for the smooth operation of large format printers. Large-format printer users should take appropriate measures to prevent the generation of static electricity. For example, in the equipment room of the equipment room to reduce static electricity sources: 1, set up a reasonable set of grounding and shielding systems for machinery and equipment: grounding is to prevent external electromagnetic interference, improve the reliability of equipment work; shielding can cut off the invasion of static noise, weaken the electromagnetic field interference. 2. The computer room floor is the main source of static electricity. The user must ensure that the resistance from the floor surface to the grounding system is between 105 and 108Ω. The lower limit value is the safety resistance value for personal protection against electric shock. The upper limit is to prevent excessive resistance. And generate static electricity. 3, staff dress should be made of materials that are not likely to produce static electricity.
In addition, large format printer manufacturers have also done a lot of work in preventing static electricity. Hewlett-Packard Co., Ltd., as the world's most famous printer manufacturer, has taken all precautions against the design and assembly of large-format printers. Static electricity measures. And on all the original media surface, are coated with a special anti-static coating, it can be said that HP's original media, have undergone a strict electrostatic test, its anti-static measures to fully comply with international standards, can ensure the safe use of equipment. If you use compatible media, there is no special coating layer on the surface, and the quality is difficult to guarantee. Even if some of the static electricity tests are taken and some measures are taken, it is difficult to completely meet the requirements of HP equipment. Static electricity is easily generated during printing. Therefore, to prevent static electricity, large format printer users must eliminate the use of compatible media.
If you use non-static test verification media, causing damage to the machine and equipment, the cost of its repair is not a few hundred, a few thousand dollars can solve the problem, but the spending of tens of thousands of dollars. In order to protect machinery and equipment, in order to protect human health, in order to better work production, HP recommends: Do not use compatible media, the original media is the greatest protection of the interests of users!
