Read This Before You Choose A Printer---Get familiar with printer supplies
We all know that the core component of the laser printer is the cartridge, toner cartridges directly affect the quality of the print, so we need to come to an independent understanding of the cartridge.
First, the importance of toner cartridges and toner Before talking about toner cartridges, we need to briefly understand the relationship between toner cartridges and laser printers, we can first look at the laser printer works! The working principle of black and white laser printer, for example, when the computer sends data to the printer through the cable, the printer will first receive the data temporarily stored in the cache, when received a complete data sent to the printer after the processor, These data are processed into data sets of similar data tables that can be used to drive the print engine. For laser printers, these signals are a set of pulses that drive the laser head.
Well, laser printers began to work, in fact, the core technology is the electronic imaging technology, which combines the principles of imaging and electronics to generate images, the core component is a photosensitive cartridge. Laser emitters emit laser light on a prism-shaped mirror, with the rotation of the mirror, the light from one end of the drum to the other end in turn sweep (half way through a variety of focusing lens, so that the surface of the drum to scan the light is very small), then the drum to 1/300 inch or 1/600 inch stride is rotated and scanned line by line in the next performed. In fact, the drum is a surface coated with organic materials, cylinder, pre-charged with, when there is light exposure to the parts of the exposure will occur resistance of the reaction. The computer sends the data signal to control the laser emission, scanning the surface of the drum in the light constantly changing, so that some places will be exposed, the resistance is smaller, the charge disappeared, and some places are not subject to light exposure, Charge, and ultimately, the drum surface formed by the charge formed by the latent image.
How does the latent image become the actual printed image?
Toner plays a key role in the toner is essentially a charge of fine plastic particles, the charge and the surface of the charge on the drum opposite polarity, when the surface of the drum with a charge through the ink roller, the charge The location of adsorption of toner particles, latent image becomes a real image. While the drum rotation, another group of transmission system will be sent to the printing paper, the print tape and the drum surface polarity of the same but much stronger charge, then the paper with toner cartridges, toner cartridges surface of the toner is attracted Onto the printing paper, the image is formed on the surface of the paper. At this time, the toner and the printer are merely attracted together by the attractive force of the charge, and the toner of the plastic mass is melted by heating at a high temperature before the printing paper is fed out to the printer, and solidifies on the surface of the paper sheet during the cooling.
After the toner is attached to the paper, the drum surface continues to rotate, passing through a cleaner that removes the remaining toner to enter the next print cycle. Can be seen in the process cartridge accounted for a very important position.
In fact, the laser printer is the most critical components. Because it not only determines the print quality is good or bad, but also determines the cost of printing. This is because the laser printer, 70% or more of the imaging units are concentrated in the drum, the print quality is good or bad in fact, it is largely determined by the cartridges. The cartridge and the printer is a consumable, the use of a period of time and reach a certain number of sheets after use need to be replaced, so choose the laser has a lot of knowledge.
Get familiar with printer supplies---Understand the classification of cartridges
In the selection of the appropriate cartridge before we first look at the classification of the cartridge. Toner cartridge is the most important kind of laser printer supplies. Laser printer cartridge by combination can be divided into the following three categories:
Integrated cartridges: photo conductor drum (photosensitive drum), drum (development roller) and toner cartridges as one of the drum. This cartridge in the design of the structure in principle does not allow users to add toner.
Binary Toner Cartridge: refers to the drum is divided into two separate parts: part of the photo conductor drum, the other part of the drum and toner cartridges. After the user runs out of toner, simply replace the drum and toner cartridge components without replacing the photo conductor drum.
Three-body cartridges: refers to the drum is divided into three separate parts: photo conductor drum, drum, toner cartridges. Replace the toner cartridge only after the user has run out of toner. Usually some manufacturers call it drum powder separation technology.
For two-body or three-body cartridge, does not mean that the use of the laser printer, the user does not need to replace the photo conductor drum, in fact, these two types of photo conductor drum and the first type of integrated cartridge, the photo conductor drum has A certain life, and some even less than the integration of the drum drum photo conductor long life. Therefore, in the purchase of laser printers, the user must pay attention.
In the photo conductor drum photosensitive material coated metal selenium alloy, because of its superior performance, reliability has been recognized by most of the world of laser manufacturers, HP, Xerox, Lexmark, Shida, Founder, and other manufacturers have chosen laser. There are also some manufacturers use ceramic surface of the photo conductor drum.
Get familiar with printer supplies---choose a good cartridge
At present, the laser are original cartridges or other companies to produce a common cartridge and refill the cartridge three. Now we will analyze the differences between these products.
We know that the print quality is certainly the first customer to consider the issue, no doubt, the original cartridge is clearly the best choice. Original cartridge As the design process carefully considered and other parts of the printer integration, the production process is meticulous, it can also create the ideal print results, much better than other compatible products. With the original print cartridge in the printer to print out the edge of the text clear, black uniform, vivid picture, but the use of alternative products when the effect will be far worse. This is because the original cartridges of the engineers in order to print the best, in the laboratory for a lot of testing and improvement, even the most minor defects must be removed and then fast. Therefore, the emphasis on print quality users usually do not hesitate to select the original cartridge.
General generic cartridges in print quality can be said to achieve the basic requirements of the printer output, but may differ in certain special circumstances, such as when printing two pounds of fine words somewhat confusing. The refilled cartridge as a result of the manufacturing process using a manual approach, print quality is good and bad, the printing effect is difficult to be guaranteed. Of course, when we consider the quality of print, print cost is also a very important consideration, especially for price-sensitive individual users. Many people will think that the original product quality is good, but at the same time the price is relatively high, this is actually an incorrect understanding, a large number of objective tests show that the original single-page printing cost is not high, the overall cost Is relatively low.
There is an independent research institutions have carried out an objective laser printer toner comparison experiment. The results showed that, in comparison with the other two original compatible cartridges, the original product cost per page and total cost of ownership (TCO) minimum, a single drum is the largest number of copies, print quality is the best.
Original cartridge due to the long service life, it saves the user money than the printer itself, the price even more. Therefore, it is recommended to use the original cartridge. Universal toner cartridge, from its print quality can be said to be able to achieve the basic requirements of the laser printer output, but there may be a special case, the distinction between generic toner cartridges are also produced brand name, product quality is guaranteed, although its price Slightly lower than the original cartridge, but the number of sheets to print less than the original cartridge, so the overall cost of printing and original cartridge is almost the same.
As for the re-filling of the cartridge although the price is very attractive, but because of its number of prints is too little or less than half of the original cartridge, so the overall cost of printing is no less than the original cartridge and universal toner cartridges.
Get familiar with printer supplies---the daily maintenance of toner cartridges
1, the installation and storage
Toner cartridge is an important component in the laser printer, a direct impact on the quality of printing. Cartridge installation is actually very simple, as long as the cartridge removed from the bag, out of the seal, and then to the drum axis axis rotation, the toner in the drum in the distribution, and then installed on the printer can be.
As for the preservation of toner cartridge, in fact, more simple. As long as the cartridges stored in the original packaging bags, can be stored at room temperature. Do not let the sun direct exposure, otherwise it will affect the life of the cartridge.
2, maintenance issues
As the laser printer imaging is dependent on the photo conductor drum exposure. When the toner cartridge encounters strong light, the inner and outer layers of the toner cartridge are turned on, so that the voltage of the toner cartridge is different from the voltage at the unexposed place, where the toner image can be attracted during the fixing process. However, a certain point of exposure to the drum time and the number of times are limited, especially in the long exposure to continuous damage to the cartridge more severe. So users usually should be used a lot of attention to the maintenance of toner cartridges.
1) Do not make the drum exposed to direct sunlight or other strong light sources.
2) Do not replace the toner cartridge in bright light, it should be as soon as possible to complete the installation process.
3) When the toner cartridge is removed from the printer, immediately put it back in the box or thick soft linen wrap.
4) If the toner cartridge from a cold place into a warm place and then set aside an hour or longer before use.
5) the drum light barrier shielded from external light source in order to protect the photosensitive drum, do not open the drum light barrier.
6) Do not touch the photosensitive drum surface by hand, and to prevent the drum surface to scratch hard objects.
7) Do not put the toner cartridge in a place of high temperature and high humidity.
8) to ensure that the cartridge away from the monitor, hard drive, floppy disk drive, or any other magnetic material.
Get familiar with printer supplies---toner cartridge maintenance small recipe
1, extend cartridge life (note: not necessarily valid)
We know that the laser printer in the use of a longer period of time after the print out of the text, the image will appear blurred, bottom ash and other phenomena. Even if the replacement of a new toner cartridge is not solve the problem, then we should take into account the problem may be a cartridge. We know that laser printer toner cartridges have a life: more than 10,000 ships, such as Hewlett-Packard, Lenovo. When the life of the cartridge to a later, there will be the phenomenon. This is mainly due to photosensitive drum surface photosensitive properties of aging, the surface potential decline, the residual voltage increases, affecting the imaging cartridge caused by (see the first part of the printing principle).
Is there any way to make the cartridge back to life? I thought of the surface of the cartridge is a layer of non-toxic organic compounds with photosensitive properties, when in the light, the coating will be conductive. In a number of chemical guidance of friends, I finally get it Cr2O3. As follows: Take to 5 g of chromium oxide, with lens paper dipped directly in one direction along the drum carefully wipe (do not wipe back and forth!) Again, to completely wipe the surface of the drum, do not miss. Wipe should be particularly careful: gentle, and then more gentle! Also note that your nails will scratch the drum tympanic membrane. Through the above-mentioned photosensitive drum can be re-printed thousands of pages to 10,000! What about it? You can save a lot of money, of course, this method may not be effective Oh.
2, full use of laser printer toner cartridges
Since Epson (Epson) series laser printer with excellent print performance and convenient operation performance in the community there are a considerable number of users. But because of its more expensive supplies and the use of the cartridge is very easy to fatigue, when the fatigue, the drum surface can not be returned in the print media will leave a very "heavy" background, a direct impact on the print.
Although the above mentioned also wipe with the chromium oxide cartridges, toner cartridge can eliminate the fatigue phenomenon, but this method may not be feasible. Because chromium oxide is solid particles (can not be dissolved), use it to wipe the surface of the drum, it may damage the drum surface. Some friends in the test of this method, but no effect, but the surface damage to the drum is very serious. After a number of tests, we also found a very simple method to eliminate the drum surface fatigue phenomenon, with this method, a cartridge can print more than 15,000 documents.
Specific methods are as follows: When the drum fatigue phenomenon, the first to remove the cartridge shell, in order to prevent damage to the drum surface, a soft cloth can be used to wrap the drum surface, remove the shell, carefully remove the cartridge, the sun exposure To two hours, although the printer manual is strictly prohibited on the cartridge under the sun exposure. But this method is indeed valid, anyway, dead horse as a living horse to medicine it! And then poured waste toner powder box, a small screwdriver can be used in the waste toner box back and forth, the toner will soon come out, this will prevent the powder when confused full "dust" flying, will be poured out Of the toner collected up and down the toner cartridge, but also for you to save an expenditure. After cleaning the surface for a soft cloth and toner cartridges some of the parts, after the installation of a good cartridge, that you are done. Then you will be pleasantly surprised to find that the original unbearable purpose of the manuscript now "clear" visible, originally very "heavy" background wiped out. The above test is a friend's personal experience, each time can be successful, you may wish to try it effective!
Get familiar with printer supplies-teach you how to repair the drum
Toner to the toner is to reduce the cost of printing the most important method. But the more the number of plus toner, toner cartridges will print quality is getting worse, generally when applied toner over two times, three times, when there will be some regular black spots, and this issue will With the increase in the number of print more and more serious. Finally, there will be printed documents blurred or print out a black mark, this time, the cartridge to scrapped, abandoned it is a pity, leaving useless, most people will choose at this time to replace the new ink cartridge.
In fact, the old cartridge is still available, there are ways to repair, that is, renewable friends. Repaired after the print cartridge quality can also be comparable with the original cartridge, and the cost is only about a quarter of the original cartridge price. This is in line with environmental requirements, but also save our money. Hearing here, is not already heart it! Well, now let us together to waste cartridges to a "back to life."
In fact, repair cartridge method can be divided into new toner and replace the photosensitive drum two parts. Following on in the usual HP 6L printer cartridges, for example, how we provide a method of regenerating the drum. First of all, to cut off the power to the printer, remove the print cartridge from the printer (this is of course, or else how to regenerate it), then pinch the side of the metal pin with a diagonal clamp, carefully pull out (or With metal nails pin into the cartridge, open the cartridge can be taken out after the metal pins), silver metal pins on both sides can be pulled out after the cartridge is divided into two parts, a light blue photosensitive selenium is a collection of waste powder part, While the one with the magnetic roller is the part for powder.
And then part of the magnetic roller for the non-rotating side of the magnetic roller screw unscrew, take the plastic shell can be seen after a plastic cover, open the plastic cover, the toner cartridge and the magnetic roller on the clean up all the toner, Be sure to clean up all the residual toner, it is best to use a vacuum cleaner net absorption. Then the magnetic roller in the reverse order of just the right, this time should be held down by the magnetic roller to prevent the magnetic roller from the original position. The toner shaken slowly into the powder for the warehouse, a good plastic cover and plastic shell should pay attention to the magnetic roller on the axle at the end of the semicircle and plastic shell on the semi-circular holes on the good. Gently rotate the gears on the sides of the magnet roll to make the toner even.
