It is understood that there are two diametrically opposed situations in the actual use of UV equipment. The UV flatbed printer of the first type of users may only be used for a few months, but it looks as old as it has been used for several years, and the machine looks dirty and messy from the outside. Especially the waste ink box part of the machine is never cleaned, but you must know that ink is a chemical composition, and it will undergo qualitative changes when it is exposed to the air for a long time. The position of the waste ink cartridge is the most frequent place where the "print head", the core component of our machine, stays. The waste ink that has undergone qualitative change will damage the "print head" through volatilization; another user's UV flatbed printer has been used for several years, but It still looks new. First of all, from the appearance, the machine is very clean and tidy, there is no dust, the paint has not peeled off, the machine has almost no scratches, and it cannot be seen that it is an old machine. From this point of view, we can analyze that the customer's machine is well maintained, because cleaning is the first step.
Speaking of maintenance, some users are lack of energy, but there are users lack of methods, simply do not know how to maintain the UV printer, the next small to share maintenance methods from multiple dimensions for your reference.
01. before starting the machine to do a good job of hygiene, timely cleaning of the machine surface dust particles, to eliminate the harm of dust on the machine and printhead. Printer working environment temperature control at 15-30 ℃ is appropriate, if the temperature is too high, too low to open the air conditioning regulation, no air conditioning should also have heating or dehumidification equipment, temperature and humidity are very important to the machine, and to do a good job of ventilation.
02. to turn on the machine in the correct order of operation (first open the control software, see the daily operating procedures), pay attention to the method and order of wiping the nozzle. (Wipe the nozzle to use professional non-woven fabric, poor quality nozzle cloth will damage the nozzle! Wipe the nozzle to gently wipe in one direction, it is strictly prohibited to wipe back and forth, wipe the nozzle of the non-woven fabric first folded, folded to the width of a centimeter or so, wipe the nozzle after wiping a color, non-woven fabric to be folded, with a clean place to wipe another color, do not wipe overlap, resulting in color tampering, the nozzle surface is a very thin plastic film, so we need to take care of).
03. printing pictures to be manned, (note that if you encounter an emergency to first press the machine's emergency stop switch to avoid greater adverse consequences of the machine continues to run), while paying attention to the deformation of the warped plate touches the printhead, otherwise it will cause permanent damage to the printhead (paint, dross blocking the spray hole, the printhead film off the scratch leading to scrap).
04. Every day before shutting down the machine to use a special non-woven fabric with cleaning solution to gently wipe the residual ink on the surface of the printhead ink, print a printhead state before closing, check the spray hole has no ink break. If there is, you need to re-press the ink, and then re-wipe the nozzle and then hit the nozzle state detection, you can generally solve.
05. UV lamp cooling water in the tank to check the level once a week, the water level is insufficient to add to the specified level in time to avoid damage caused by insufficient heat dissipation UV lamp . In winter, the water must be replaced with antifreeze, such as in areas with freezing weather use, it is recommended to directly fill the antifreeze to avoid damage to equipment due to freezing.
06. UV printer shutdown should also follow the order of software priority, first off the control software, then off the graphics software, then off the computer, and then off the machine, shut down all electrical equipment, the second cartridge valve to remember to close, or the next day, then the ink will flow dry.
07.The moving parts of the UV printer should be oiled regularly. The x-axis and y-axis are high-precision parts. The guiding part of the X-axis and Y-axis should be lubricated regularly. Too much dust and dirt will cause excessive resistance of the mechanical transmission part and affect the accuracy of the moving parts (such as the guide and the filament rod are too dirty. It is recommended to use a non-woven cloth before oiling. A little lubricating oil to wipe clean), it is recommended to use low-viscosity lubricating oil such as sewing machine oil for filling oil, so as to avoid the excessive viscosity of the lubricating oil from bringing resistance to the operation of the equipment.
08. check the ground wire frequently to ensure its safe grounding and forbid to start the machine before it is reliably grounded;
09. If the voltage in the area is unstable, it must be equipped with a regulated power supply (10KV) and make sure it works properly. Before starting the machine must ensure that the temperature and voltage power supply is stable. UV printer lines to avoid using the same circuit with high-powered electrical equipment, and regularly check whether the line is damaged;
10. machine on when not printing, remember to turn off the UV lamp at any time, the purpose of one is to save power, the other is to extend the life of the UV lamp
For the practical part of the operation, the need for UV printer installation and commissioning at home, should follow the actual guidance of technical personnel taught from. If you have more maintenance tips, welcome to leave a message at the end of the article.
