Symptoms and solutions of inkjet printer failure

Symptoms and solutions of inkjet printer failure 1. Regarding the nozzle of the printer is clogged, the nozzle is dripping ink. The nozzle can be opened for nozzle flushing. 2. There is no ink pressure, please check whether the ink filling tube in the ink tank is blocked, and check whether the filter should be replaced, and then adjust the ink pressure to the specified value; 3. The main ink filter is severely clogged, it is recommended to replace the main filter. 4. The MCU board is disturbed, restart, edit characters, set parameters, and discharge through the electrostatic code machine main board. Solutions to this problem of fuzzy breakpoints: 1. The breakpoint value is not adjusted properly, you need to adjust the breakpoint value, you can spray characters during the adjustment until the appropriate value; 2. The phase light is often on or flashes frequently. 3. If the ink viscosity is incorrect, adjust the ink viscosity; 4. The nozzle is slightly clogged, and the nozzle needs to be opened. 5. The main ink is blocked by the main ink filter and needs to be cleaned or replaced. 6. The ink pressure is improperly adjusted. Adjust the ink pressure according to the user manual. 7. The positive pressure of the nozzle is too large, readjust the positive pressure of the nozzle. Solution steps for nozzle clogging: 1. Carry out the nozzle opening procedure, if there is no effect, you can block the recovery nozzle, increase the ink pressure at the same time, and execute the opening nozzle of the printer; 2. Take out the nozzle with a water spray wrench, put it in a container filled with thinner or detergent to soak for a period of time, and then try again. 3. If there is an ultrasonic cleaning machine, the ultrasonic cleaning machine can be used to clean the nozzle. Note: When installing, do not install the reverse direction. The font should be installed down. The effect of the inkjet printer is not ideal, and the printed words are confused or misplaced. Solution: 1. Editing errors, you can not use the arrow keys to replace the space bar or delete the content, because it is cleared; 2. The MCU board main board is disturbed, re-screen and edit, or try to switch the machine again. Shows lack of diluent during use. Solution: 1. There is no diluent or a small amount of diluent in the diluent bottle, add appropriate amount of diluent. 2. The distance between the proximity switch assembly and the diluent bottle is long, and the diluent bottle cannot be detected. Adjust the position of the diluent bottle so that it is close to the switch. 3. By reducing the sensitivity of the proximity switch, adjust the potentiometer on the proximity switch to improve the detection sensitivity, so as to ensure the accuracy of signal triggering.
