[pco]A few days ago, nline industry watch saw a comment from a friend of the internet saying, “seeing on the internet, on the one hand, that selenium-compatible drums are protecting health, printing quality, and that the combined costs are far less than the original beryllium drums. I wonder, how different are they? That's what made me think of writing this article。
Skull drum empty box/squirty drum counter-false mark recovery
Before that, printers were chickens, consumables and eggs, and printers were more dependent on the sale of eggs, but with the development of the mobile internet and the dramatic leap forward of paperless offices, printing demand fell rapidly, the printing market as a whole was under-appreciated, and the hewlett-packard, which had traditionally lived as a leader, fell into a vortex, or became the next giant to implement it. In order to regain their share of business, the plant began to change its business model and hit it while applying low-cost strategies like bulldozers. The share of domestic raw, counterfeit and by-product consumption in the market, as revealed by industry, is about 4:4:2 and the market share of generic and counterfeit materials is not a small figure。
First of all, it is necessary to get rid of the counterfeit and the by-products. So-called counterfeit materials, in short, are dog meat sold with sheep heads, usually produced in two ways: the acquisition of used raw waste drums for reprocessing and the acquisition of high imitations. Unlike the by-products, they put more articles on the surface, which, frankly, is to impersonate the original and to falsify the truth, which is why they represent such a large market share because of several times the windfall. The method of sale is simple, or it is a switch, which is to change the selenium drums inside the printer secretly, and the ordinary consumer will not recognize that it is good if they can print properly, or that they are sold at a low price, or even in collusion, in some government purchases, you know... With regard to the quality of printing, four words are used to describe it as “a mess” in which it is inevitable to expect those workshops to do some fine work, which is less demanding in the process and which is accompanied by a reduction in the amount of work done。
In order to maximize the cost of controlling carbon powder, which is less adsorbed, there is waste in use and direct access to the waste powder warehouse, which is designed to be calculated on the basis of the rate of use of carbon powder in the original beryllium drums, which cannot match the original design of the printer, so when too much non-original carbon powder is cleared to the waste powder warehouse, there is an explosion and a leak, which directly results in a reduction in the volume of the output, which is described as 2,000 pages, and 1,000 pages can be printed when carbon powder is depleted。
In addition, the rough surfaces of the drum cores of the selenium drums after hand-drinking, with visible scratches, and the relative frequency of their use before the drums, the original drums are unlikely to have any scratches, which has a direct impact on the printing effect, so that the text marks are generally lighter and lighter, the print lines are broken, and sometimes blank pages are printed because of the thicker particles of the drums, which cause partial loss of light when the drum cores are cut. In addition, this pseudo-simultaneous drum, which in the course of its operation leaks carbon powder into paper-cleaning wheels and breakers, results in the loss of paper or a few pieces of paper at a time, and if it leaks to circuit boards, the conductivity of carbon powder leads to the burning of circuit boards, which is certainly not alarming. Of course, a lot of catalogs can be seen from overpacks, foam bags, metal components, which are not always presented here, and in one sentence, “the cheap ones are untrustworthy, the pail is a bogus mass, and if you don't worry, go straight to the b2c electrician, even the agent is a fake, and i don't usually tell him”。
So is there a big difference between the by-product and the original? There was a difference, but not to the extent that some media were exaggerated. Their greatest difference lies in the quality control, the truth, the interest in the printing industry, the fact that they have purchased many compatible acreage drums over the years. Even with such big cards as tianwei, the quality control of the product is still at a level of 70 points. The problem usually arises after the printing of 500 pages, such as powder, for which i do not have to prove much. It is possible to go to electricians like kyoto and yee-hyun to see the evaluation system, most of the users’ points are still credible (in other words, i usually see only a rating and a poor rating)。
Second, the first use of print quality is still off, but after the powdering, there are a variety of minor situations, such as the emergence of false wires and black spots (the original beryllium drums are usually powdered three times)。
Thirdly, while not as serious as fake selenium drums, it is normal to say that 1,500 pages can be printed and 1,000 pages actually printed, while the original americium drums can generally be printed up to 1,300 pages, as manufacturers deliberately leave space for powdering to prevent the reduction of the life and stability of the selenium drums。
The last point concerns carbon powder, which is also the largest difference between the original plant and the secondary plant. The carbon powder that produces images on the paper surface is mainly produced in a number of ways, the first of which is physical grinding, which has the advantage of being cost-effective, but the carbon powder particles that are grinding are uneven and not uniform in shape, which may affect the quality of printing at the time of imaging. The second approach is chemical synthesis, which uses chemical methods to form different materials into a spherical carbon powder, resulting in high image brightness and high charge, low melting point and fine parity, and easy to print high-quality documents. As far as we know, a significant proportion of the by-products are still using irregular non-spherical carbon powder, so when the printout is magnified, it is found that the handwriting is not as smooth as that of spherical carbon powder. Hewlett-packard, samsung, fuscow, and yoshinaga have been developing new carbon powders that have sought breakthroughs in several ways, firstly in terms of environmental protection, the use of a percentage of bioreleaf or the reduction of the fixed temperature, and secondly in terms of increasing the fixed level of carbon powder so that it can quickly penetrate the fibres that enter the paper。
Summarize our views. Two things, one is not to be greedy and avoid buying fake selenium drums, and that's a big loss. The second point is that the by-product selenium drums are indeed higher in value than the original plant's aluminum drums, which is unquestionably more expensive than they are, but it is not too easy to shake a few blocks, squeeze the water out of the parameters, at best at half the cost of printing, which is not as perfect as some manufacturers boast, and the gap exists, which must be acknowledged, but it is not so obvious that ordinary office use is acceptable. Finally, it should be stressed that since the sub-supplier is chosen to buy as large a deal as possible, some of the unnamed small brands are not even as good as fake。
