Introduction: copier daily maintenance of experience sharing. Office equipment is currently developing at a rapid pace, accompanied by a fast-paced work environment, few people to pay attention to or understand these things, because office supplies in a company to see, basically are housekeeping and small things, do not know that the daily some small details on the can help you solve a lot of unintended problems. We should pay attention to, the daily correct use of the method is particularly important, there may be an inadvertent small action will cause damage to parts. Here I summarize some of the small details to share with you.
Copy machine maintenance common sense
1, electrostatic copier technology in good condition of the main standards
(1) drive system to start to be easy to run smoothly, no abnormal sound, should not be overheated.
(2) optical system either desktop or fixed electrostatic copier on the optical system of the lens, reflector lens and light source have strict requirements. Requirements for the lens to be clean, reflective lenses in addition to keep clean, do not casually move, change position, so as not to affect the value of the angle of incidence and reflection. The light source must be clean, do not have obstacles caused by shade, so that the light path is not accessible, affecting the exposure, charging, transfer, power dissipation and other normal work.
(3) copier to be faithful to the original from the copy of whether the copy is faithful to the original, can reflect the performance of the electrostatic copier and the work of the state of good and bad. To determine the performance of the electrostatic copier is mainly based on the black value of the copy, the size of the bottom gray, contrast, resolution, layering and so on. Blackness refers to the optical reflection density of the black area of the copy, the smaller the value of the electrostatic copier is better. Resolution refers to the number of line pairs contained in each millimeter that can be clearly distinguished on the copy, and the more line pairs it contains, the better the performance of the electrostatic copier. Layers of sense refers to the copy of the test board on the gray level of the copying effect, the richer the level of electrostatic copier performance is better.
2, copy 3000 sheets of maintenance
Remove the waste powder box, pour off the waste powder, wipe the box clean and loaded into the machine, and then pull out the electrodes, wipe the electrode filaments, gate filaments and electrode holders; clean the bottom of the developer on the top and bottom of the guide cardboard, the separation of the rollers, the separation of the belt; and finally clean the manuscript table glass.
3, copy 10,000 sheets of maintenance first 3,000 sheets of maintenance. Take out the developer, remove the dust plate on the developer roller, check the surface of the developer roller, if there is any abnormality, to be dealt with; wipe the paper feed mouth cardboard. Remove the developer shroud and replace the fixing cleaning felt and the upper and lower separation claws. Remove the toner and grease that falls on the lower part of the fixer, and then disassemble the lower surface of the glass of the original manuscript table for cleaning treatment. Remove the toner cartridge and wipe it with lens paper.
4, copy 50,000 sheets of maintenance
(1) for copying 10,000 sheets of maintenance
(2) clean the optical system
① scanner cleaning. Scanner drive by the scanning drive mechanism to complete, if the scanner guide is too dirty, will increase the scanning resistance, so the scanner should be regularly cleaned and lubricated. Remove the glass of the original manuscript table, clean the guide rail, repeatedly wipe a few times, and then add a small amount of oil on the linoleum of the guide rail. Push the scanner back and forth a few times by hand, so that the surface of the guide rail to form a thin film of oil, check the scanner in the process of moving whether the resistance encountered, whether there is an abnormal sound, after the end of the work, you can by the way the scanning area to eliminate the dust.
② reflector, reflector and lens cleaning. Reflectors, mirrors and lenses on the accumulation of too much dust will hinder the `spread of light, affecting the quality of copying. Cleaning methods are as follows: open the original desk cover, remove the original desk glass, so that a piece of reflector in the middle position, and then wipe with lens paper, not too much force, not back and forth wipe. If there are stains on the reflector can not be wiped off, glass cleaner can be used to clean, but also can only be cleaned in one direction, the other pieces of the reflector with the same method of cleaning. The fourth reflector in the dark box, lift the cover, you can see. The method of cleaning the reflector is the same as above.
③ Clean the sealing glass. Because through the reflector, the lens to the drum on the light, the middle has to pass through the sealing glass. When it falls above the dust, the same will appear on the copy of the bottom gray, affecting the quality of the copy.
(3) Check the scraper
Remove the drum cleaner, check the scraper, if damaged should be replaced. The replaced scraper should be coated with a little toner on the edge, and finally check the draft table drive steel cord, if twisted or damaged should be replaced.
5. Maintenance Notes
①Main power switch should be turned off during maintenance, and the power plug should be unplugged, so as not to short-circuit the static copier by touching metal tools.
② The use of a variety of solvents should be strictly in accordance with the requirements of the operation, not corrosion-resistant parts can not use solvent cleaning. The use of open flames should be avoided.
③ Some insulating parts with alcohol and other wipes must wait for the liquid to completely evaporate before loading the copier, otherwise it will make it aging.
④ When using lubricants, it is necessary to follow the requirements of the manual, and the general plastic and rubber parts must not be refueled, otherwise it will make it aging.
⑤ When disassembling a part, pay attention to the order of removal. When there are more parts, you can record them in case you forget. Especially washers, springs, bearings and the like should be operated in the reverse order when installing.
⑥ The screws used inside and outside the machine are easy to confuse, and should be placed separately after removal, so as not to get on the wrong, so that it will be damaged.
⑦ In the disassembly of the internal drive chain, belt, gears, should remember the direction, generally available paper can be drawn down before disassembling, so as not to install the wrong, so that the machine is damaged.
1, choose the right place to install the copy, pay attention to high temperature, dust, shock, and direct sunlight, and at the same time to ensure that the ventilation environment is good, because the copier will produce a trace amount of ozone, and the operator should be more Every working period of time to the outdoor air to rest for a moment. Minimize moving in normal times, and if you want to move it, it must be moved horizontally, not tilted. For optimal operation, allow at least 90 centimeters on the left and right sides of the machine and 13 centimeters on the back (about 23 centimeters if the machine is connected to a separator), and operate and use the copier with care.
2, should be used to use a stable AC power connection, the power supply should be fixed for: 220-240V, 50Hz, 15A.
3, every morning after work, to open the copier to warm up preheating half an hour or so, so that the inside of the copier to keep dry.
4, to keep the copier glass table clean, no scratches, no correction fluid, fingerprints and other spots, otherwise it will affect the copying effect. If there are spots, use a soft glass cleaner to clean the glass.
5, in the copier work process must be in the cover above the blocking plate, in order to reduce the glare on the eyes of the stimulation.
6, if you need to copy books and other documents that need to be bound, please choose the one with ?
Data Ready
Data Ready is a video ready to go. (split scan feature) performance of the copier. This eliminates copying shadows due to uneven binding.
7. If the background of your copy has a shadow, then the lens of your copier may have dust on it. At this point, you need to have your copier professionally cleaned.
8, when the copier face plate shows a red light to add powder signal users should be timely on the copier to add toner, if the powder is not timely can cause the copier malfunction or produce powder impact noise. When adding toner, you should shake the toner loose and operate it according to the instructions. The paper in the tray should not exceed the thickness allowed by the copier, please consult the manual to determine the thickness range. In order to keep the paper dry, you can place a box of desiccant in the copier's paper box, and you should wrap the copy paper and put it in a dry cabinet after using it every day.
10, after each use of the copier, be sure to wash your hands in a timely manner to eliminate the residual dust on the hands of human injury.
11, the work of the end of the day to close the copier power switch, cut off the power. Not to close the machine switch to pull the power plug, which will easily cause machine failure.
12, if the following conditions occur, please turn off the power immediately, and ask the maintenance personnel. a, the machine issued a strange noise; B, the machine shell becomes too hot; C, the machine part is damaged; D, the machine was rained or water inside the machine.
Therefore, in our daily work, we should pay attention to the cleaning and maintenance of the copier. Usually, users can do the following:
1, cover cleaning
As a result of contact with a variety of original manuscripts and being hand-held touch, will make the white plastic lining or conveyor belt black, resulting in copies of the edges and corners of the black stains. Use cotton gauze dipped in some detergent to wipe repeatedly, then wipe with water, and then wipe dry can be. Note: Do not wipe with organic solvents such as alcohol and ether.
2. Clean the glass of the desk
Because the glass of the desk is easy to be stained by the manuscript and hand, and also easy to be scratched, so it should be regularly cleaned and maintained in order to ensure good copying results. To avoid direct hand contact with the table glass during work, if there is binding, the original should be removed from the big head pin, curved pin, staples, etc., and placed in the designated location. Make sure to wait until the correction fluid has dried before copying the corrected original. When cleaning the glass of the manuscript table, avoid wiping with organic solvents. Because the glass is coated with a translucent coating and a conductive coating, these coatings are not soluble in water, but in organic substances.
3, the circuit system
The circuit system for a long time in the high-pressure work, adsorption of a large number of dust, resulting in a decrease in the resistivity between the electronic components, causing the current breakthrough of the electronic components, burned circuit boards. The following parts of the cleaning work should be carried out by specialized technicians: the cleaning of the optical system, the cleaning of the mechanical system, the cleaning of the paper feeding system, the cleaning of the paper discharging system.
4, remove the waste ink cartridges
Carefully remove the waste ink cartridges, in order to prevent the ink powder in the air is too much inhaled by the human body.
5. Replacement parts
After copying to a certain number of sheets, the consumable parts of the copier (e.g., cleaning scraper, electrode filament, separating claw (sheet), rubbing wheel, etc., which are not free of charge during the warranty period) may need to be replaced as necessary due to wear and tear. And this type of maintenance and spare parts costs of expenditure, is normal, should not be considered as the quality of the equipment.
