| 1. The electric eye is not adjusted properly 2. The electric eye is damaged 3. The printing mode is set incorrectly |
| 18.Ink line position jitter |
| Answer: 1. The nozzle is blocked. Clean the nozzle. 2. The filter is blocked and the pressure is unstable. Replace the filter or maintain the machine |
| 19.Ink on the recovery pipe |
| Answer: 1. The ink viscosity is abnormal. 2. The breakpoint is not well split. 3. The inkline is not in the right position. 4. The ink has expired and deteriorated |
| 20.The machine interface shows that the solvent is too low. Please install a new solvent box |
| Answer: replace the solvent box or add new ink to the solvent box until the warning is removed |
| 21.During normal operation, the machine interface shows that the ink path pressure is low |
| Answer: 1. Check whether the pump has rotating speed or not. 2. Ink leakage in ink pipeline. 3. Pressure sensor is damaged |
| 22.What is the pressure of ink path in standby mode |
| Answer: generally at + / – 100 |
| 23.When the machine is running normally, the interface shows that the vacuum pressure is abnormal |
| Answer: check whether the ink pipeline leaks, especially the two ink supply pipes connected to the pump |
| 24.High pressure deflector absorbs ink when inkjet printing |
| Answer: 1. Check whether the ink viscosity is normal 2. Check the breakpoint splitting 3. Test the voltage of high-voltage deflection plate (normal about 170V) |
| 25.Ventilation fault |
| Answer: 1. The fan does not rotate and is damaged 2. The main board is damaged |
| 26.Ink points are not well split |
