Since the typical loss material of the stress is mainly a powder cartridge, the quality of the output sample is mainly dependent on the quality of the powder cartridge. Below, I will talk about some laser printer powder cartridges for similar questions for peers.
First, the structure and general working principle of the laser printer cartridge
The structure of the laser printer cartridge is generally composed of a photosensitive drum, a carbon powder bin, a waste powder collection medium, a waste powder scraper, a variety of cover plates. The working principle is such that the laser beam emitted by the laser, and is transmitted into the acoustic deflection modulator by the reflective mirror, and the binary graphic information sent by the computer is sent to the glyph generator from the interface. Form a binary pulse information of the desired glyph. The signal generated by the synchronizer controls 9 high-frequency oscillators, and then adds a frequency synthesizer and power amplifier to the acoustic modulator, modulation of laser beams injected from the reflective lens, and the modulated beam is injected into multiple faces The mirror, and the wide-angle focus mirror returns the beam to the surface of the light toner drum. The surface of the light guide drum is charged by the charging, so that it obtains a certain potential, and then the exposure of the laser beam containing the graphic image information is formed, and the electrostatic latent image is formed on the surface of the light-tubular drum, and the magnetic brush display is developed to make the toner cartridge surface. The latent image is sucking toner, then the latent image is converted to a visible ink powder, and when the transfer area is passed, the toner is transferred to ordinary paper under the electric field of the transfer electrode. Finally, the preheating plate and the high temperature heat roll fixing, that is, the text and images are melted on paper.
Before printing the graphic information, the cleaning roller (or cleaning blade) removes unmoping toner clearance, unscrupulous lamp (or electrodes) removes the drums of residual charge, and then thoroughly cleaned by the cleaning system. The residual toner and some paper powder suck in the waste powder collection position to enter a new round of work cycle.
Second, the update of the laser printer cartridge
The laser printer powder cartridge is in use, the most susceptible loss is carbon powder, followed by a photosensitive drum, a scraper, and the like. For a powder box, if it is because the toner consumption or the drum is used to use life and other parts damage, the entire powder box will be discarded, re-purchase the new powder box, and it will be a bit waste, a powder box general price is 400 Yuan (A4 specification) to 1500 yuan (B4 or A3 specification) is even higher. As long as we have a certain understanding of the structure and working principle of the powder cartridge, it can be updated by replacement. And this price is much cheaper than re-purchase new powder box. For example, a bottle of toner is generally only, only the entire powder box 1/10 ~ 1/5, a photosensitive drum price is only about 1/4 of the entire powder box, a new powder box can generally fill 3 ~ 5 carbon powder, can also fill the toner again by replacing the drum, and now replacing the toner cartridge is far more than the original toner cartridge. For general units and individuals, replacing new powder boxes and updated powder boxes can save a lot of expenses, while the laser printer cartridge is updated, mainly to add toner (powder) and replacement drum. Below, I talked about the replacement of the powder and photosensitive drums of the general powder box.
Some reports have been added for the addition of laser printer toners. But most people's operation is not very ideal. If most users are drilled a hole in the powder box, then pour the carbon powder, and then seal the cave. This may just generally use people with a laser printer that is not very inner way. Of course, this is the problem that can solve a moment, but this is to solve a lot of real problems. Because the toner is not just simply putting the toner into the powder box, it will become a good thing. When we print, we also check if the mounted powder is even distributed on the magnetic rod, otherwise it will make the output of the output The toner is uniform, and this will make the machine yourself even have a lot of samples, causing unnecessary waste, and cannot be used when the sample is required; second, to check if the waste powder collection is full Waste powder, these waste pownsicks must be cleaned in time, if so, not only cause "leakage" phenomenon, so that the output is not ideal or even unused, and then "leak powder", after a period of time, It will cause damage to the drum, which is mainly because the waste powder warehouse (somewhere) is serious, but cannot inhale waste powder, causing the phenomenon of "leakage powder", which will continue to waste powder (including paper powder and some paper fibers) ) The photosensitive drum surface is seriously friction and damage the photosensitive drum. Therefore, in general, the toner should be added to the normal operation method, and the cleaning of the powder cartridge can be truly solved. The general method of printing is as follows:
First, use the two metal laps (or four plastic laps, more early products) on both sides of the powder cartridge to pull out, if it is really unable to pull out, generally, the same size of iron nails will carefully Knock it inside, pay attention to the pulling cap should not be pulled in the pin cap, but then pull the bullets at the bottom of the pin. When first pulling plastic laps, pay attention to can't clamping the pin head and pull hard, so it is not easy to pull it out, or even damage the latch, this is because the plastic latch tail has a flashboard. Therefore, the slice should be clamped with tools such as forceps, and the card is launched, and the pin is clamped with the tip clamp. When you put it up, you can scrape off the card head on the shrapnel so that you may pull it directly with a spleble clamp. Next, the spring is taken under the spring of the powder cartridge and the waste powder collection, so that the two parts are separated, open the lid of the carbon powder bin (some of the laser printer carbon powder warehouse has a cover, can release the screw first. After removing the cover, the high-quality toner corresponding to the printer model (the carbon powder of the laser printer cannot be used with the toner of the electrostatic copier), and then use the funnel (or roll into a funnel shape with paper, staple Good) slowly pour the toner into the carbon powder, pay attention to the powder, do not install too much, cover the powder warehouse cover, shake the powder box axially, and rotate the magnetic rod with hand. The connection of the gear) makes the toner distribution on the magnetic rod, if it is not uniform, the magnetic bar can be rotated in turn to bring the magnetic iron powder carrier, and the iron powder has a much consciously bullionally On the place, the magnetic rod is rotated clockwise, so that the iron powder is transferred to the carbon powder warehouse, so that the powder will come to a paragraph. If it is the second time, it is necessary to consider the discharge of the waste powder in the waste powder collection (can be collected by the waste powder, remove the foreign matter, and then load the carbon powder bin to make a general proof ), Cleaning the dirt of toner and paper powder around the clean. Carefully remove the toner cartridge (i.e., photosensitive drum) when clearing the waste powder. Generally, the screws of the toner cartridge are first removed, unplug the plastic (or metal) latch, because the two-headed latches are different, so they should be remembered, and it is not possible. Then take the toner cartridge carefully, do not place the toner cartridge in the light of glare, and be careful, don't let it encounter other hard objects to avoid being scratched. Then, the waste powder is poured, wipe the surrounding of the clean waste powder with a soft thing, such as cotton, should be careful not to deform the rubber scraper, so as not to contact the toner cartridge, make the printed sheet to produce ground or black point. After the above work is completed, you can carefully install the toner cartridge and powder cartridge. Remember each screw, toner cartridge, and the position of the latch is not wrong when installing, so as not to damage the powder box. After installing, you can try a few, if it is normal, the whole work is done, if it is not normal, then the cause should be analyzed, check whether the above steps and parts are installed correctly, and there is no damage. There is also a toner cartridge such as HP5L, HP6L, etc., pay attention to the laps, sometimes it is pressed into the toner cartridge, which is because the position of the load is not aligned, so that The metal rod on the latch cannot be contacted with the metal sheet in the toner cartridge, so that the surface of the toner cartridge cannot produce static electricity and cannot generate a laser lame in the toner cartridge to adsorb toner, so that the output of the output is a blank paper. There is also as unlaminated with the toner cartridge, which will make the sample ash and black spots. It should be carefully checked and excluded.
