green laser pointer  influences people’s life greatly. If the laser is certainly good, it may charge electrode and the grid circuit; scan drive circuit logic error; cartridge components discharge bad; signal cable is not connected. Check the location and repair methods: first replace the cartridge components to see if the problem disappears, if so, then the problem is the cartridge components, the replacement of the. Appear the phenomenon of the entire page black, indicating the laser is definitely good. Therefore, it can be replaced a new cartridge to re-print, if the fault is removed, it is sufficient to prove that the cartridge components in question, then can check the drum charge pole, magnetic roller drum eliminate bias electrode and the electrode is good contact , if points were bad, you should find and fix. Then check the charging wire and the grid is short circuit or poor contact, and if so, should replace the repair or cleaning. We know that the vast majority of cartridge components due to different structural models are not the same, but ...
... its working principle is the same. 200mW Laser Pointer  is used more and more widely.

Charge on the use of wire cartridge, if the wire insulation block has char, rather than the phenomenon, available multimeter measuring the resistance profile between the wire and the grid to see whether short-circuit, short, or if the resistance is small, clean or replace the insulation blocks. In addition, the wire can also cause pollution or displacement of this fault, it is necessary to clean or correct wire. If these checks are good, then the fault may be components in the laser scanning frequency drive circuit or logic circuit, it should check the scan logic circuit is damaged, replace the scanning assembly. Sometimes, because of a printer with multiple computers linked to the signal line often plug (we oppose the use of a signal line is often the way to plug multiple computers together, because it will be very likely to cause foot and socket signal line damage), leaving the signal cord is damaged or inserted is not strong, so that some signals can not pass, then the output will result in failure of black proofs, so check is to check the signal cable is plugged in good condition and to avoid other unnecessary overhaul. Scraper scraper or damaged drum on the drum on the Liverpool scratch; magnetic roller scraper local damage; printer (general guidance paper channels) is toner contamination.  100mW laser pointer contains some other parts.

General repair methods: first proofs of the Black Belt is observed output was fuzzy like, and if so, clean or replace the drum scraper. If not, then check the drum vertical traces have been scratched, and if so, check whether the local drum scraper damage, in general, output proofs on the vertical black line shows the drum longitudinal (circumferential direction ) more visible scratches, which can only replace the drum, but it should also carefully check whether the cleaning blade favorable viscous material or damage, should remove or replace scraper, so as not to scratch the drum again. If it is not the issue on the photosensitive drum, magnetic roller scraper can check whether a foreign body or a defect, it would not achieve the role of restrictions toner, toner and imaging drum beat is not the distance between the magnetic roller on the local direct adhesion of toner to the photosensitive drum surface to form a black line. The solution is to clean the magnetic roller on the magnetic roller scraper scraper or replacement. In addition to these two reasons, the printer (paper general guidance channels) is also formed black toner contamination of failure. When the printer paper path inside the paper guide together on the melting of the toner, paper to print through the friction when the paper will form a black line. The weight of Blue Laser Pointer is 0.5 kg.

For this reason the formation of the black line, the general bias change, line edge is vague, as the above two reasons clear, the channel was contaminated most of the toner transfer wheel, the upper and lower heating rollers and other parts, so to remove This can turn the printer off when hot to remove these dirt. However, if the upper and lower heat roller caused by damage or aging, although cleaning will solve the problem temporarily, but soon will reproduce the failure, it should consider replacing the upper and lower heat roller. Although many models of laser printers, but because it works and the materials used are basically the same, but some specifications is different, so the general maintenance for laser printers, are all suitable for a variety of laser printers, but there are some special The difference only. Because there are remnants of printer toner, dust and scraps of paper and other debris, charge, transfer, separation and eliminate electrode wire will be contaminated, so that the voltage drop, affecting the normal performance. In general, if the charge transfer electrode wire contamination of the waste toner, paper dust, etc., will print out a hard copy is not enough ink, or even very light, mainly due to dirty electrode wire less charge on the drum after the Therefore it is latent image produced on the drum of the toner-low voltage is not enough and suction, leaving the contaminated wire transfer voltage is not enough, then walked to the paper when the paper is not close enough contact with the cartridge, leaving the transfer not enough toner to the paper, so will the output of the pattern ink is too light. In addition, the transfer electrode wire (slot) serious pollution cases will make the output of the pattern on the back of dirt, because the output pattern wire transfer to go through the slot. And eliminate pollution of the electrode separation will make the paper jams and other faults arising from poor. 5mW laser pointer is very easy to operate.

Eliminate electrode contamination is the residual toner on the drum will not clean sweep, the output of the pattern bottom ash serious. Maintenance should be careful to remove the wire electrode wire assembly (some printer models do not have to remove the machine wire, can be cleaned up directly on the machine), his first brush with the brush attachment on a foreign body, followed by cotton and then spend it carefully and gently wipe clean. When the laser scanning system of lasers and mirrors all the work to be dust and other pollution, will result in increased bottom ash prints, images unclear. Can wipe them clean, cotton flower, but be careful not to change their original position or break something. Fuser maintenance of the main part of the heated fuser roller (including rubber roller), separation claw, thermal resistance and thermal switches. The business scope ofgreen laser pointer covers main domestic developed cities.
