[Office Partner Information Center] With the increasing application of photocopiers, the development of the functions is also very fast. From the original simple copy to the double-sided copying and double-sided printing, the increase in the functionality makes many users use it. It is difficult to operate correctly. The author has compiled some basic knowledge about the maintenance of the laminating machine for everyone today, hoping that it will be helpful for everyone to use the laminator. 1. The main technical standards for electrostatic photocopiers (1) The drive system should be easy to start, the operation should be stable, no abnormal noise, and should not be overheated. (2) Optical system Whether it is a desktop or fixed electrostatic copier, there are strict requirements on the lens, reflective lens, and light source of the optical system. The lens is required to be clean, and the reflective lens should not be moved or changed in position unless it is kept clean, so as not to affect the values ​​of its incident angle and reflection angle. The light source must be clean, do not have obstacles cause shading, make the light path unreasonable, affect the exposure lamp reflector, charge, transfer, eliminate electricity and other normal work. (3) The copying machine should be faithful to whether the original is faithful to the original from the copy, reflecting the performance of the electrostatic copying machine and the working conditions. Judging the performance of the electrostatic copier is mainly based on the blackness value of the copy, bottom ash size, contrast, resolution, and layering. Darkness refers to the optical reflection density of the black area of ​​the copy. The smaller the value, the better the electrostatic copying machine. Resolution refers to the number of lines per millimeter that can be clearly identified on a copy. The more lines included, the better the performance of the electrostatic copier. Hierarchy refers to the effect of copying on the grey level of the test board. The richer the level, the better the performance of the electrostatic copier. 2, copy 3000 maintenance Take out the waste toner box, discard the waste powder, clean the box and put it into the machine, then pull out the electrodes, wipe the electrode wire, grid wire and electrode holder; clean the upper and lower paper guides on the bottom of the developer, separate the rollers, separate Band; Finally, clean the platen glass. 3, copy 10000 maintenance First 3000 maintenance. Take out the developer, remove the dust-proof plate on the developer roller, check the surface of the developer roller, and if any abnormality, handle it; wipe the cardboard at the feed port. Remove the fuser cover, replace the fixing wipe and the upper and lower separation claws. Remove the toner and grease that have fallen on the lower part of the fuser, and then remove the lower surface of the original platen glass for cleaning. Remove the cartridge and wipe it with lens paper. 4, copy 50,000 maintenance (1) Make 10,000 copies for maintenance (2) Cleaning the optical system 1 scanner cleaning. The scanner drive is done by the scan drive mechanism. If the scanner's guide rail is too dirty, it will increase the scanning resistance. Therefore, the scanner should be cleaned and lubricated regularly. Remove the original table glass, clean the guide rail, wipe it several times, and then apply a small amount of oil to the felt on the guide rail. Move the scanner back and forth several times by hand to form a thin film of oil on the surface of the guide rail. Check whether the scanner meets the resistance during movement and whether there is any abnormal sound. After the work is completed, the dust in the scanning area can be dropped. eliminate. 2Reflector, mirror and lens cleaning. If too much dust accumulates on the reflector, mirror, and lens, it will hinder the spread of light and affect copy quality. The cleaning method is as follows: Open the original cover, remove the original table glass, make a mirror in the middle position, and then use the lens paper to wipe, can not be too much force, can not wipe back and forth. If there is a stain on the mirror that cannot be wiped off, it can be cleaned with a glass cleaner. It can only be cleaned in a single direction. Other mirrors are cleaned in the same way. The fourth mirror is in the dark box. Open the cover and you can see it. The method of cleaning the reflector is the same as the method above. 3 Clean the sealing glass. Because through the mirror, the lens reaches the light on the drum, but also through the seal glass. When there is dust on it, the bottom ash will also appear on the copy, affecting the quality of copies. (3) inspection scraper Remove the drum cleaner, inspect the scraper, and replace if damaged. Replace the scraper should be painted on the edge of a little toner, and finally check the platen drive steel wire rope, if there is a twist or damage should be replaced. 6, maintenance and care matters 1 The main power switch of the copier should be turned off during maintenance, and the power plug must be unplugged to prevent the electrophotographic copier from being short-circuited by touching the metal tool. 2 When using various solvents, strictly follow the requirements. Components that are not resistant to corrosion must not be cleaned with solvents. Avoid open flame when using. 3 Some insulating parts must be wiped with alcohol, etc., and must be completely volatilized before being mounted on the copier. Otherwise, they will deteriorate. 4 When using lubricating oil, follow the requirements of the instruction manual. General plastic and rubber parts must not be refueled, otherwise it will make them aging. 5 When removing a part, pay attention to the order of removal. When there are many parts, it can be recorded to prevent forgetting. In particular, washers, springs, bearings, and the like should be installed in reverse order. 6 The screws used inside and outside the machine are confusing. They should be placed separately after removal to avoid mistakes and damage. 7 When disassembling the inner drive chain, belts, and gears, you should keep in mind the direction of the drive. Generally, you can use the paper to draw it down and then remove it to prevent mis-assembly and damage.
