Thereby preventing the toner from the drum transferred to the print paper, can also cause the formation of a narrow white stripe on the printed sheet. The toner cartridge failure, usually caused by a large area writing fades. Remove the toner cartridge gently shake the box toner evenly distributed, if we continue to improve much, should replace the toner cartridge. Laser printer to print black. Paper unilateral fault phenomenon: the printer in the print, the print output of blank paper. Analysis and processing: this failure may be developing roller is not bothered by the toner caused (the DC voltage of the developing roller is not added), it may be ungrounded drum, due to the negative charge can not be gravitropism unloading put the laser beam can not The drum work, drum rotation, does not generate images to go to the print paper. The design discussion meeting of laser pointer is to be held.The trial run of production of laser pointer has been finished
Turn the printer off, remove the toner cartridge, open the lid on the notch, and again make a mark in the non-photosensitive parts of the drum into the printer, start running for a while, and then Turn off the printer to remove the check mark whether the move , can determine the drum is working properly. If the toner is not normal for the flute in the laser beam is blocked, can also cause white paper. Therefore, should check the toner runs out, the correct print cartridges into the machine, the sealing tape has been removed or laser irradiation on the channel blocking properties. Concluded that: does not seem to drum Toner laser printer paper black unilateral failure phenomenon: the laser printer in the print, sometimes cardboard, and sometimes do not take paper. In short, the paper feed is not always smooth. It is for the necessary reference of laser pointer .
May be found in the crack extends to and departure from the bottom left the centreline of the trench to draw CO2 laser. Nd - YAG laser drawing and cracks have directly together. Abstract In order to investigate the application of substrate on the back of the depth of China's distribution of this groove-crack, CO2 laser has become twoparts draw to break it along the line is drawn. Scanning electron micrographs of cross-sectional groove-cracks shown in Figure 6. Obviously, this groove-crack can be separate into four distinct areas: it is to use A, B, C and D. secondisthe siphon evaporation Thefirstisthelaser columnar grain region and the intergranular fracture region. The formation of ditch in the first region. The parts and components of laser pointer contain a lot.
It is during the technology discussion meeting of laser pointer
