At present most of the carbon powder production mainly by two ways, the early physical grinding method, its characteristic is directly grinding carbon powder, toner particles is irregular, the other is a currently popular chemical synthesis method, the carbon powder shape is spherical, more even.
The main component of carbon powder is not carbon, but mostly consists of resin and carbon black, charge agent, magnetic powder and so on. Toner by high temperature melting into the paper fiber, resin will improve font gloss and waterproof, resin after high temperature at the time, will inevitably produce waste gas, the original consumables vendors in developing carbon powder, as far as possible reduce the powdered carbon emissions, but is still unable to avoid. In addition, laser ionized air can produce ozone. The main components of carbon powder of laser printer such as cf410x includes: f-fe3o4 crystal powder (PLGMENT) : 20-30%; styrene copolymer: 50-60%; Charge regulator CCA: 10-20%; Liquid SiO2, etc.; Surface modifier polyethylene/polypropylene paraffin wax. The particles, made of these compounds, are about 6-8 microns in size, very delicate and even. Besides grinding method and chemical synthetic method, carbon powder with the progress of technology and continuously improve production technology, there is a way to use the zero bounds fluid melt-blown technology to produce carbon powder, spherical carbon powder particles can be obtained, the advantages of this approach is that the rest of the material can be reused, not much emissions, relative environmental protection. Grinding method of the production of carbon powder, by contrast, although the cost is low, but uneven toner particles, irregular shape, so the utilization rate of carbon powder may have certain discount, and in paper form a handwriting was not as clear as homogeneous spherical carbon powder and fine. There is a link in the chemical synthesis process to dry the carbon powder, so the production cycle will be relatively long and the production cost will increase. In the future, if there is an updated technology that can produce carbon powder such as the toner in hp toner cartridges at very low cost, and can obtain uniform and delicate spherical carbon powder, it will be favored by the carbon powder producers.

Cartridge laser printer is the key components, we found the same type of cartridges in the shop, the price difference up to 4,5 times, which in the end what is the reason?
1, whether the quality is good or bad Laser printer operation, more than 70% of the imaging components are concentrated in the cartridge, the print quality is good or bad in fact largely determined by the cartridge. A good print cartridge clear, text black, paper pages clean, not because of the installation of different sizes of the mold is not installed in place, the installation does not go in, cannot be installed out. 2, print costs Drum cartridge parts in the printer drum, drum core with high-quality photosensitive effect, a good toner have the corresponding drum core like some high quality cf410a toners which are more wear-resistant, print structured. Bad drum core life is short, the printing effect of some shallow, and some deep, seriously affecting the print quality. Just no problem printing on the machine, there will be some problems after printing hundreds of pages. 3, machine damage Toner in the cartridge quality is good or bad, decided to liquidity, uniform particles, fixed firmly, the average print black above 1.4, not good toner particles, fixing is not strong, gently wipe the handwriting which will fall , A long time leakage, stuck in the fixing device easy to jam, damage to the fuser. 4, good health Some toner prints smell, impure resin content, long-term use of eye discomfort, dizziness, nausea and discomfort, resulting in poor mood, harmful to the body. 5, environmental pollution Not good toner cartridge, the material is easy to bend, resulting in leakage powder, less print volume, often have to go to clean up, missing a lot of powder caused by office pollution. Summary: A good selection of the best and cheap toner cartridges matching program, after repeated testing to ensure quality and stability. The cost of inferior toner cartridge is 4.5 times higher than that of high quality. The fundamental reason is that the cartridge used by the completely different accessories. Nowadays, many domestic manufacturers have one-sided control over the cost. Some low-cost and low-cost OPC cores and charge rollers (PCR) are used. Some even directly remove the accessories from the used toner cartridges. The use of such a cartridge may be no problem in the early days, after printing hundreds of pages there will be a variety of problems. Due to not get a good after-sales service, the subsequent costs even doubled. Recommend that you use the stable quality, after-sale guaranteed high-quality toner cartridges. ColorSphere third-generation bright color toner technology to some extent changed the internal structure of the toner: hard shell soft core. C, M, Y, K four-color toner –HP cf410x is easier to absorb the paper, vivid color vivid paper. After using ColorSphere's third-generation bright color toner, the color saturation of the graphic is high, the clarity of the paper is high, and the color is more vivid and beautiful. This is the third-generation toner technology to bring the most direct sensory experience M477fdw. With the help of this technology, the capacity of toner cartridges is also relatively increased, and the corresponding increase in print volume up.
M477fdw overall appearance HP Color LaserJet Pro MFP M477fdw the main color with a white, which makes M477fdw look more beautiful fashion, is the latest choice for the fashion business-class users. The size of the machine is also more reasonable design, can save a certain amount of office space, but with the same amount of print-level enterprise printer may not have such a figure! Scanning part The scanning section of the HP Color LaserJet Pro MFP M477fdw refers to the ADF Feeder and Scanning Platform mentioned above. As an enterprise-class one machine, the combination of the two scanning methods is more and more manufacturer attention. Control panel VS USB flash memory jack HP M477fdw control panel is designed to be touchable display, the bottom of the screen design of the three touch buttons for the HOME key, the return key, and the help key. In addition the size of the touch screen is 4.3 inches, compared to ultra-white HP M277dw and double-sided geek M427fdw, the HP M477fdw touch screen larger. Appearance is completed, the touch screen features more internal, such as: copy, scan, wireless settings and so on. The specific function will be elaborated below in the system. In summary, the birth of HP M477fdw with new generation hp toner cartridges, mainly for the new technology support. M477fdw will also take advantage of new technologies to better, higher, faster use of the experience to the vast number of users. In fact, the technical level is not so simple, nor is it a word or two to describe in detail. We will HP Color LaserJet Pro MFP M477fdw detailed evaluation, so that everyone understand the M477fdw at the same time, be able to HP's latest technology has a more in-depth understanding. Toner cartridge according to the structure points, there are two major integrated and separate, one cartridge is the cartridge and the drum together, when the toner is exhausted or drum damage, the entire cartridge almost scrapped. The following for everyone to explain the structure of laser printer cartridges and maintenance methods, I hope everyone can help from this.
According to the structure, the selenium drum is mainly divided into two parts: the integral and the separate type such as cf410x. The integrated toner cartridge is packaged with the carbon box and the photosensitive drum. The separation cartridge and the drum are separated separately, so the lifetime of the photoreceptor drum is generally longer. Although the lower the cost of follow-up separate cartridges, but in general, the single printing cost of one type cartridge printer is lower than that of the separate type. After making clear the structure of the selenium drum of the laser printer, the user can choose the consumable products according to the local conditions. Generally speaking, there are three kinds of options: original cartridges, compatible cartridges, regenerated or powdered selenium drum. Print quality, original toner is the obvious choice, but its price is generally high; compatible toner has a good price, suitable for printing quality without demanding; regeneration or powder toner by manual way, the toner poured into the printing quality uneven in quality, the effect is difficult to guarantee, and may damage the printer do not recommend the use of. Therefore, users must comprehensively measure their print, print quality and printing costs, and make reasonable choices according to the actual needs. The use and maintenance of the toner drum is very simple, but very important. The new toner cartridge such as hp toner cartridges for initial use, must be pulled out of the seal, the force should be uniform, to avoid excessive force to seal completely unable to pull out; do not touch the surface of the photosensitive drum with your fingers or a hard object, so as to avoid dirty or torn surface of the photosensitive drum; don't let the toner exposed to direct sunlight or other strong light; do not let the toner cartridge contact with any magnetic material. At the same time, as the selenium drum is an important part of the laser printer, good printer usage will also prolong the service life of the printer and toner cartridges. If we use only the print medium approved by laser printer, keep printing media clean and neat, do not curl and fold, so as not to produce paper wring phenomenon. Do not let office supplies such as pins, pins and paper into the printer, so as not to break the surface of printer heating film and photosensitive drum. . Strengthen cost control is a key part of the enterprise in competition, but instead of blindly pursue cost reduction will bring more waste, so I need to long-term, global vision to look at the business enterprise operation, scientific and reasonable to reduce costs. There is an important indicator TCO: Total Cost of Ownership has the Total Cost of Ownership, including the Total Cost of purchasing from the product to later use and maintenance.
According to the survey, only 13% of the printing TCO is used for the purchase of hardware equipment, and 87% is the cost of printing consumables, post-management and maintenance of printing equipment. The latter may seem unimpressive, but it has been quietly gathering and building up, greatly increasing the cost burden for customers. Only refined printing management can effectively control printing waste costs. This requires the ability of the printer to provide refined management and an intelligent solution. For example, the HP printers' printing solution can help enterprises reduce their carbon consumption and energy consumption. Like hp Color LaserJet Pro M452nw Toner provide color priority printing, double-sided or multi-in-one printing, etc. Color priority printing, automatic preference to color print mode, avoid unnecessary black-and=white printing, reduce waste; double-sided printing, paper can be automatically turned on page, reduce paper consumption 50%; Print more in one, and scale the contents of two or more pages onto a sheet of paper to save paper and toner. At the same time, the HP toner particles to be more careful than traditional carbon powder evenly, make the printout thin and symmetry, and it requires that the melt temperature is lower than ordinary printer, so can reduce the dosage of carbon powder and energy consumption. To excessive printing behavior constraints and management, HP print management solutions, according to different department or personal usage of printing equipment and the use of information, and print output automatically generated monthly statistics report, can always monitor the state of equipment, consumables and use, according to their own business need to be flexible to print management, so as to significantly improve the production efficiency of the printer. This can improve intensive management and effective cost control for enterprises with large printing consumption, which will encourage the company TCO to control more stringent and create benefits for the company. Only According to the printing consumables such as HP Color LaserJet Pro M452nw’ internal structures - hp cf410a toner and the printing management comprehensive consideration, we can avoid the huge waste of the printings and improve wok productivity. When we purchase the laser printer cartridges, pay attention to the quality of the high-quality cartridges, otherwise the purchase of the bad goods will reduce the life of the printer and further greatly increase the printing cost. We should not greed for cheap, and it’s best to go to the regular supplies shop to buy. In addition, I want to share some of my experience to you and I wish this will be helpful to you.
1. The package is important The appearance of the super-class color laser toner cartridge is beautifully printed and brightly colored. The serial numbers on the back are printed with special techniques, and the background color has a rectangular offset. But bad-quality cartridge doesn’t have the same situation. The outer packing of the bad one is rough, blurred and gray. For example, the reliable toner cartridge of HP cf410a has a laser anti-counterfeiting label attached to the box, and the color will change between black and blue as the angle of observation is different. Even if the reliable compatible hp cf410a toner has distinct colorful packaging, not unlike the inferior one, you may obviously feel it unreliable for its dim colors and fuzzy appearances. 2. The connection. In the use of old toner drum self-filling, JS will inevitably have “action “in the connection part of the toner cartridges. If the connection part has a “washed” trace or the blue layer of the screw (the black heat treatment layer) is damaged, it’s likely to be recycled. 3. The printing materials. Print out the sample sheet with the best cartridges, the image and the files are not only fine and clearly, but also have good adhesion. But the quality of the printed sample is less when printing toner cartridges with not good or self-filling toner. some of the inferior toner printing on the paper, with the fingers can wipe out the printed handwriting; some of the drum powder particles are thinker, which has a greatly harmful to both environment and people’s healthy. The damage of the drum core caused the local to be unable to sensitized, which will form forever blank on the paper surface, some will appear the word strokes broken phenomenon. 4. The quality of the toner. Although the printing quality of laser printer mainly depends on the resolution of laser printer, it is also directly related to the size of carbon powder particles. The high performance hp toner has the outstanding play, such as you will get more steady and durable printing results without any impurities. One ways for ordinary user to judge the quality of the toner is printing a completely black sample with a laser printer equipped with this cartridges, and see if the black distribution on the paper is even. If the distribution is even then the toner is credible, and you can consider to change a new toner cartridge if you find it’s not uneven. |
