Matters Needing Attention during the Brother Cartridges Disassembly
Today, we are here to talk in details about the brother toner cartridges in the disassembly process needs attention. Let me take the common brother cartridge- tn660, as a concrete instant. 
First, the trial turn: cartridge used in the machine, the drum, charging roller, magnetic roller is rotating, after assembling these parts, to promote its drive gear, check whether the flexible rotation. When the toner cartridge is loaded, press the drum gear again to push the drum gear in the normal direction of rotation to ensure that the toner cartridge can be flexibly rotated before the toner cartridge can fall, as this may damage the machine.
Second, positioning problems: Each part has its own fixed position, by spring or screw positioning, and the two parts of the powder warehouse and waste toner warehouse by plastic clips, screws or connecting shaft positioning. Assembly parts must be installed in place, so that the toner can fall normally.
Third, the electrical contact: All brother toner cartridges, magnetic roller, charging roller has electrical contacts connected with the machine, the assembly should pay attention to clean and electrical contact point at the connection.
Fourth, the magnetic roller: magnetic roller black coating is the most easily scratched, magnetic roller is composed of aluminum sleeve and the core, due to the role of the core, some small pieces of metal can easily be adsorbed to the magnetic roller surface, During the relative movement, the magnetic coating will be crossed out. In addition, during the folding process, the magnetic roller is also easily adsorbed to the surrounding metal parts, resulting in unexpected coating damage. The lack of a black coating can result in a lack of text or graphics on the print. So disassembly, the magnetic roller to take a firm, can’t be placed with the clock, should be placed away from other metal parts, to avoid bumps.
Fifth, the photosensitive drum: photosensitive drum surface coating easily bruised, scratched, and vulnerable to light damage. Improper handling is likely to make a good drum in an instant with its normal service life, so in the process of folding, not only to avoid direct sunlight, but also to avoid long-term exposure to fluorescent lamps, except yellow light Damage to the drum. Do not allow hard objects to collide with the surface of the drum. Do not touch the print area of the drum directly with your hands to avoid perspiration and oil stains, resulting in poor prints. Protect brother toner cartridges, start from the internal photosensitive drum.
