13 Maintenance Tips For UV Printers

UV printer equipment presents a phenomenon of polarization in actual use. The first type of advertising production company machine did not take long, or it took only a few months, but it took a few years, and the machine was dirty and chaotic from the outside. In particular, the waste ink cartridge part of the machine is never cleaned. It is necessary to know that the ink is a chemical component and will change its quality for a long time. This position is the most common place for the core nozzle of our machine. Is harmful to the nozzle;

Another type of advertising production company used a few years to buy it for a few months. First of all, from the appearance, the machine is very clean and tidy, no ash, no paint, no machine scratches, no point at all. It is the old machine. From this point of analysis, the customer's machine is well maintained, because cleaning is the first step.

When it comes to maintenance, some advertising production companies are lack of energy, but some companies lack methods, they simply do not know how to maintain a delicate UV printer, and then share maintenance methods for your reference.

1. Do a good job of sanitation before starting the machine to prevent the damage of dust to the machine and the nozzle. The temperature of the air conditioner is controlled at about 25 degrees. There is no equipment for heating or dehumidification without air conditioning. Temperature and temperature are very important to the machine, and ventilation is required.

2, the boot should be operated in the correct order (first open the control software, see the daily operating procedures), pay attention to the method and sequence of wiping the nozzle. (Use a professional nozzle cloth for wiping the nozzle, and the inferior nozzle cloth will damage the nozzle!) Before pressing the ink, ensure that the valve is closed and the ink path is cut off. (The wiper should be wiped gently in one direction, and it is strictly forbidden to rub back and forth. The non-woven fabric of the nozzle is folded in half, and folded to a width of about one centimeter. When the color is wiped out after the nozzle is wiped, the non-woven fabric should be folded up, and another color should be rubbed in a clean place. The color of the nozzle is a thin plastic film on the surface of the nozzle, and the plastic film is peeled off, that is, the nozzle is scrapped).

3, when printing pictures, someone should be on duty (note that when the machine is wrong, you must first press the emergency stop switch at all angles of the machine to avoid further adverse consequences), and pay attention to the deformation of the raised plate is strictly prohibited to collide with the nozzle. Otherwise, it will cause permanent damage to the nozzle (paint, slag blocking the nozzle, nozzle film peeling off and scrapping).

4. Before shutting down every day, use a special cotton swab to pick up the cleaning solution and gently wipe the residual ink on the surface of the nozzle. Before closing, print a nozzle and check whether the nozzle is broken. If so, use a light-colored spot color to print, the color block is 10% - 20% solid color.

5, air pump, oil-water separator (including the main separator of the UV printer built-in small oil-water separator and air pump connection) to drain oil regularly (half a month);

6, UV lamp filter cotton should be replaced regularly, (otherwise it is easy to cause damage to the lamp, serious accidents and damage to the machine) filter cotton is related to UV lamp dust, heat. The ideal life of the lamp is about 500-800 hours, so it is necessary to make a record of daily use time;

7, UV printer shutdown should also respect the software priority order, first off the control software, then close the mapping software, then turn off the computer, then turn off the device, turn off all electrical equipment, secondary cartridge valve to remember to close, otherwise In the past two days, the ink has dried up, but now some manufacturers have a backup UPS power supply. After the machine power is turned off, the negative pressure system can be guaranteed to work normally. Of course, if conditions permit, it is better to let the machine not shut down. Always in the standby state, the effect can be large, and experienced people know that when the machine is working again the next day, there is no need to perform the action of starting the ink press, and it is known how expensive the ink is, and some of them are reluctant to press.

8. The front part of the car is covered with a cloth with better shading effect, which protects the nozzle from light and dust.

9, UV printer main filter and secondary filter should be replaced regularly (three months for a cycle). The ink pump should be inspected regularly, the ink pump does not rotate or the speed does not reach the demand of ink supply, that is, the ink supply motor continues to run, and the control software generally has a prompt: (the ink cartridge is in a state of lack of ink for a long time or the ink cartridge is in the state of ink supply for a long time) Replace it in time;

10. The moving parts of the UV flatbed printer should be regularly filled with oil and oiled. The X-axis Y-axis is a high-precision component. In particular, the X-axis portion with a high running speed is a consumable part. The X-axis conveyor belt should be inspected regularly to ensure proper tightness. The X-axis and Y-axis guide rails should be lubricated regularly. Excessive dust and dirt will cause excessive resistance in the mechanical transmission and affect the accuracy of moving parts. The oil injection of the guide rail includes: lubricating the rail portion and lubricating the lubricant in the slider portion;

11. Always check the ground wire (good for two ground wires) to ensure that it is safely grounded. It is forbidden to turn on the machine before the machine is connected to a reliable ground wire.

12. A regulated power supply (10KV) must be provided and ensure that it is working properly. Make sure the temperature and voltage supply is stable before starting the machine. UV flatbed printer lines should avoid using the same circuit as high-power electrical equipment, and regularly check whether the lines are worn or not;

13. When the machine is turned on and not printed, remember to turn off the UV lamp at any time. The purpose is to save power and the other is to extend the life of the UV class.

For the actual operation part, when the UV printer is required to install and debug the door, the technician actually guides the teaching.
