What should be paid attention to when adding powder to laser printer

First, to understand your toner cartridge assembly state that is included in the drum assembly is suitable for the direct filling of toner, only in the imaging unit of the various components in good condition, you can get a satisfactory print quality. The specific method is to fill in the toner before printing some proofs to determine whether the drum assembly needs to replace some parts, if there is a printing defect, in order to ensure the quality of printing, must replace the relevant parts;

Second, before dismantling the toner cartridge should be prepared a small box storage parts, to prevent the loss of small parts.

Third, the demolition of the photosensitive drum is the most critical and most vulnerable parts of the surface of the photosensitive drum of Organic Light guide layer is easily touched, scratched, easy to be exposed to strong lighting damage. Improper handling is likely to make a good photoptic drum in the printing of the defect, so in the folding process, not only to avoid direct sunlight, but also to avoid the long fluorescent lamp irradiation. Prohibit the hard object impact drum surface, and prohibit hand directly touch drum printing area coating, lest leave perspiration, grease, resulting in bad print.

Four, the dismantling of magnetic roller is the most important part of the printing product blackness, the thickness and roughness of the black coating will change with the constant use. The black coating of the magnetic roll is the most easily scratched, the magnetic roll is made up of aluminum sets and cores, due to the role of the magnetic core, some small metal pieces are easily adsorbed to the surface of the magnetic roll, in the relative moving process, the magnetic sleeve coating will be crossed off. In addition, in the process of folding, the magnetic roller is also easy to be adsorbed on the surrounding metal parts, resulting in accidental coating damage. The lack of a black coating produces a lack of text or patterns on the printed product. So in the disassembly, the magnetic roll to hold steady, not casually placed, to be placed away from other metal parts of the place, to avoid the impact of hard objects. Blow off the magnetic roller suction adsorption toner, if the black coating on the magnetic roll looks very thin, and even saw the color of the aluminum base or the surface looks very light, then such a magnetic roll produced by the printing will be shallow, should be replaced by a new magnetic roll or magnetic roll sleeve.

Five, remove powder bin scraper out of the powder knife is under the magnetic roll, control the magnetic roll on the thickness of the toner layer, and to assist the toner friction charged parts, is made of metal stamping parts and a polyurethane rubber strips, rubber bar to have a certain degree of hardness, straight to evenly control the thickness of carbon powder layer and can effectively make the toner charged, long time of friction, The rubber part will be aging deformation bending loss of elasticity, this will lose its application function. Printing products will be excellent light, black spots, black lines, uneven blackness, and even the problem of leaking powder. After the aging of rubber strips can not be restored, only to change the new.

Six, the dismantling clean scraper cleaning scraper and the powder bin Scraper's composition is very similar, only a slightly more rigid polyurethane rubber, of course, its function and powder bin scraper is not the same, clean scraper rubber material status and blade is very important, long time after the use of rubber will be aging deformation, knife edge often appear gap, The printed product will produce a partial bottom ash or vertical light black line. Such a cleaning scraper can no longer be used. Need to replace the new cleaning scraper in time.

The surface layer of the charge roller of the charge roller is often used for a long time to use the bonded toner, toner additives and paper scraps, etc., will wear, these phenomena will cause the bottom ash or print black spots, etc., fill the toner before, with a soft cloth light rub (can cooperate with some special reagent, avoid using alcohol), be sure to clean its surface as much as possible, In order to effectively charge the photoconductor drum. If it is found that the surface has been damaged, then do not use, if continue to use the words not only affect the charge, but also penetrate the drum core.

Eight, scraper and scraping plate with the use of sealing function. When the scraper deformation, it is easy to cause waste toner cartridge leakage, on the surface of the printed product left irregular dots, black line.

Nine, electrical contact all drum assembly in the photoconductor drum, magnetic rollers, charge rollers have contact with the machine, in the Assembly should pay attention to the contact point of cleaning and conduction.

X. Positioning problems each part has its own fixed position, generally rely on PIN or screw positioning, and the powder bin and waste powder bin two parts do not rely on plastic clips, screws or connecting shaft core positioning. Assembly of the components must be installed in place, so that the cartridge can be used normally.

Xi. when the drum is used in the machine, the photoconductor drums, the charge roller and the magnetic roll are turned, and after assembling these parts, the driving gear should be driven to check whether it can rotate flexibly. When the powder box is finished, it is necessary to push the drum gear again according to the normal rotation direction of the drum, to ensure that the drum can be flexibly rotated after the cartridge can be used, otherwise it will damage the machine.
