1. Ensure that the environment around the UV tablet printer is clean. Too much dust in the working environment will easily lead to poor lubrication of the trolley guide shaft, which will block the movement of the print head during the printing process, resulting in inaccurate printing position or impact on the mechanical frame, resulting in damage and crash. When the print head is restarted without returning to the original position, the printer will first return the print head to the original position, and then clean the printheads, which will cause unnecessary waste of ink. The way to solve this problem is to often wipe off the dust on the guide shaft and lubricate the guide shaft (choose lubricating oil with good fluidity, such as sewing oil).
2. Ensure that the UV printer has a stable working platform, and do not place any objects on the top of the UV printer. The front cover of the printer must be closed during printing to prevent dust from entering the machine or other hard objects from hindering the movement of the printer trolley. It is forbidden to plug and unplug the printer cable with power, which will damage the printer’s print port and the PC’s parallel port, or even the PC’s motherboard. If the print output is not very clear, the printer’s automatic cleaning function can be used to clean the nozzle, but a small amount of ink will be consumed. If you are still not satisfied with the printing after several times of continuous cleaning, you may have run out of ink and need to replace the ink cartridge.
3. Before turning off the printer, return the print head to the initial position (the print head will automatically return to the initial position when the printer is suspended). This is to avoid waste of ink when the printer is restarted to clean the nozzle the next time it is turned on. It is also because the nozzle can be sealed by the protective cover at the initial position, so that the nozzle is not easy to be blocked.
4. The ink cartridge needs regular correction: users with printer experience know that the printer needs to be corrected after the ink cartridge is reinstalled or replaced with a new ink cartridge to improve the printing accuracy and quality.
5. When the ink cartridge is not used up, it is best not to remove it, so as to avoid ink waste or ink metering error of the printer.
6. The ink cartridge should be kept at room temperature to avoid direct sunlight when it is not used for a long time. Because the ink evaporates quickly in this environment, it is easy to cause nozzle blockage. In addition, in the low temperature and humid environment, the print head circuit and ink are prone to problems.
7. When replacing the ink cartridge, be sure to follow the steps in the operation manual. Pay special attention to the above operations when the power is turned on. After replacing the ink cartridge, the printer will refill the ink delivery system. This process cannot be carried out when the printer is turned off, and the printer cannot detect the reinstalled ink cartridge. In addition, some printers use the electronic counter inside the printer to measure the ink capacity (especially in the statistics of color ink usage). When the counter reaches a certain value, the printer judges that the ink is exhausted. During cartridge replacement, the printer will reset its internal electronic counter to confirm that a new cartridge is installed.
8. In addition, the grating strip of the UV flat-panel printer should also be well protected. Do not touch it with your hands. Do not let it be contaminated with dust to prevent inaccurate positioning.
