1. The inkjet printer is sensitive to static electricity. The ground of the equipment should be handled under the guidance of the installer. 2. When operating the control panel or sprinkler, be sure to disconnect the power supply and have anti-static measures. 3, inkjet files in the computer system should be cleaned at any time to ensure that the hard disk has enough space. 4. When the inkjet software is used, it cannot open other programs, nor can it open two inkjet programs. 5. During the inkjet process, you cannot transfer files to the control computer. 6, the computer system parameter settings can not be changed, especially when reinstalling the system to ensure accurate settings. 7. The data transmission cable in the towline must be regularly checked for wear and tear to ensure that there is no open circuit, short circuit and signal interference. 8, if the canvas roll does not move, will bring the screen horizontal stripes, but also make the canvas walk size is not accurate, you can open the canvas to make cloth walk evenly. 9. The parameters of vertical stepping are adjusted in the driver software. Refer to the software instructions for adjustment method. 10, the noise of walking on the trolley increases, check the wear of the slider or head and tail bearing. 11. When the motor is energized, you cannot push the car. Otherwise, it will easily lead to misalignment. 12. The parameters of the driver have been adjusted at the factory, users can not arbitrarily change, such as the use of motor failure, please observe the motor alarm signal in detail, by the professional reference manual processing. 13. The tightness of the timing belt tension should be appropriate. If it is too tight or too loose, adjust it with adjusting bolts. 14. Each tube interface of the ink supply system must be guaranteed not to leak. Check whether the ink supply of the ink cartridge is normal, and ensure that the interface of the ink supply tube of the nozzle is not leaky, and the ink in the ink supply tube has no air bubbles, otherwise the ink supply will be insufficient. 15. If it is found that the ink speed is slow, you must check or replace the filter. 16. Before the nozzle is powered on, ink should be supplied first, because ink is the main way to take away the heat of the nozzle. 17. The hood should be used when printing, to prevent the ink from contaminating the nozzle, connecting port, nozzle separation board, etc. Otherwise, it may easily cause a short circuit accident and damage the nozzle.
