In the process of using carbon powder compact, 郭cheng) , if can't print in which the full white or light and fuzzy and level bearing, mainly due to what? Carbon powder, copier toner supply manufacturers - — Here and everybody simple analysis ( 分析) As follows: first, print out the full white or light and fuzzy: 1. Seal has not opened; 2. Compact pull seal before shaking, the powder is not smooth; 3. Laser is not according to the drum, powder compact mask did not open, a drum cover not open; 4. Inside the drum drum bad earth, conducting strip or cartridges are connected to the machine electrical contact point contact bad ( Loose line) 。 Second, level error, is mainly refers to the horizontal intermittent printing on printing out: 1. Printer toner according to different requirements, the carbon powder production to develop in the direction of refinement, color and high speed. Carbon powder manufacturing mainly adopts FenSuiFa and polymerization. Drum coating have exposure ( 曝光) ; 2. Color is used in the paper in the laser printer toner fixing powder material. Black toner by bonding resin, carbon black, electronic agents, additives such as ingredients. Still need to add other color in the color toner pigment, etc. Drum drive gear defect, loose or tooth defect; 3. Magnetic roller ( gǔn) Coating locating defects; 4. Color is used in the paper in the laser printer toner fixing powder material. Black toner by bonding resin, carbon black, electronic agents, additives such as ingredients. Still need to add other color in the color toner pigment, etc. Magnetic core breaking or location error; 5. Magnetic roll sheath serious wear and tear, A basic type of component failure) Or deformation; 6. Magnetic roller ( gǔn) The conductive spring ( 春天) Poor contact or beating.
