| 3.machine encoder connection |
| Answer: 1 pin. 2 pins for power line, 4 pins for signal line and ground wire |
| 4.During normal operation, the screen shows eht trip |
| Answer: 1. Check whether there is ink on the high-pressure deflection plate 2. Check whether breakpoint splitting is normal |
| 5.During normal operation, the ink line is offset, and the screen shows that the recycling tank is faulty |
| Answer: the ink line is biased, because the nozzle is blocked, and the ink line is not put into the recycling tank. Carry out the nozzle cleaning in the system setting, and the cleaning pot will squeeze the cleaning liquid toward the nozzle until the nozzle is put into the correct position of the recycling tank |
| 6.During normal operation, the ink line is in the correct position of the recovery tank, the recovery tank does not recover, and a recovery fault is reported |
| Answer: check the recovery electronic valve, which may be blocked or damaged |
| 7.How to judge whether the electronic valve is blocked or broken |
| Answer: enter the advanced password, select the electronic valve test in the system settings. Generally, the electronic valve is blocked if there is no current and the electronic valve is damaged |
| 8.There is no noise and no current in the test of ink core electronic valve |
| Answer: 1. The ink core cable may be loose or damaged. 2. The ink core board or main board may be damaged |
| 9.During normal operation, the screen shows that the ink level is empty |
| Answer: 1. The pipeline may leak ink. 2. The ink core plate may be damaged or the ground wire of the ink core may be loose |
| 10.Start up and run, the screen shows pump fault |
| Answer: 1. Generally, the pump speed is too high, more than 2000. Check whether the ink core leaks. 2. Filter is blocked |
| 11.The screen shows that the service time of ink core expires |
| Answer: replace the corresponding ink core board or the whole ink core |
| 12.The screen shows that the nozzle temperature is too high or too low |
| Answer: generally, the valve module is damaged |
| 13.During normal operation, the phase threshold value displayed on the screen is wrong |
| Answer: generally, the main board is damaged |
| 14.During normal operation, the screen shows that the ink viscosity is too high |
| Answer: the instruction does not automatically add solvent, check the solvent adding valve |
| 15.The screen shows that the ink viscosity is too low |
| Answer: do not switch on and off the machine frequently. Every time the machine is switched on and off, the system will automatically clean the nozzle, which will cause the ink core ink viscosity to be too low. Let the ink line run automatically until the warning is removed |
| 16.Normal startup, no flight time |
| Answer:generally, the ink points are not well split or crystal vibration is damaged |
| 17.Ink cartridge not recognized by machine |
| Answer:maybe the ink box is not inserted in place or the ink box has been inserted more than 5 times or the ink chip has expired |
| 18.Insert the ink box, and the screen displays the wrong ink box or solvent box |
| Answer: the ink box model or solvent box model does not conform to the actual machine ink model or solvent box model |
| 19.During normal operation, the screen shows that the pressure is too high or too low |
| Answer:1. High pressure indicates high ink viscosity 2. Low pressure indicates low ink viscosity, which is usually accompanied by ink viscosity failure |
| 20.Screen mixing cylinder liquid level high |
| Answer: it may be that the nozzle is cleaned frequently or the viscosity of the original ink is high. Select the nozzle throat in the system setting to clean and discharge the ink until the failure icon disappears |
| 21.During normal operation, the screen always shows that the liquid level of mixing cylinder is low |
| A: generally, the ink adding valve is blocked or damaged, and the ink cannot be pumped into the mixing cylinder |
| 22.The screen shows that the chassis temperature is too high |
| A: the ambient temperature is too high or the fan is damaged. It may also be a problem with the main board |
| 23.When printing normally, the icon of printing interval too short is displayed |
| A: increase the speed of the production line or decrease the movement speed of the product |
| 24.When printing normally, the delay of the display product is too short |
| A: increase the delay of the product or the distance between the eye and the nozzle |
| 25.When printing normally, the screen displays printing overspeed |
| Answer: the encoder speed is too high, and the production line speed setting is slower |
| 26.What is the actual height of the minimum and maximum font that can be printed on the small type machine |
| Answer: minimum (5 dot matrix) height 2 mm maximum (34 dot matrix) height 10 mm |
| 27.No display on power on screen |
| Answer: there is no voltage in the power supply, maybe the power cord is not plugged in or the power supply of the machine is damaged |
| 28.Turn on the power supply screen, white screen, no content display |
| Answer: 1. The cable from the display screen to the main board is not plugged in. 2. The main board is damaged. 3. The display module is damaged |
| 29.Poor print quality or incomplete characters |
| Answer: 1. The nozzle is too far away from the product 2. The breakpoint is not good 3. The ink is hung on the recycling pipe 4. The font width is set too small 5. The charging is not good and the ink is out of date |
| 30.No fault prompt, not printed on the product |
| Answer: 1. The word width or printing delay is not set correctly. 2. The eye is not adjusted properly. 3. The printing mode is set incorrectly. Change the printing mode |
| 31.Correct adjustment method of electric eye |
| Answer: adjust the electric eye up and down. When the product passes through the electric eye, the electric eye light is on. The product is not out of date and the light is off |
| 32.Product leakage during production |
| 1. The electric eye is not adjusted properly 2. The electric eye is damaged 3. The printing mode is set incorrectly |
| 33.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 |
| 34.Ink on the recovery pipe |
| A: 1. The ink viscosity is abnormal. 2. The breakpoint is not well split. 3. The ink line is not in the right position. 4. The ink has expired and deteriorated |
| 35.Where to look in the diagnosis interface |
| Answer: press the I key in the lower left corner of the keyboard to view |
| 36.What is the advanced code of inkjet printer? How to input? |
| Answer: press F4 to input 9999 directly, and then press enter |
| 37.The machine prints normally, and the upper half of the font is missing |
| Answer: the ink line is not in the right position in the recycling tank. The ink line is too close to the middle. |
| 38.When the machine is running normally, the ink line often deviates |
| Answer: 1. The nozzle is damaged. 2. The ink path is dirty and needs maintenance |
| 39.Ink points are not well split |
| Answer: 1. Adjust modulation voltage 2. Replace crystal oscillator voltage 3. Ink quality problem |
| 40.High pressure deflector absorbs ink when inkjet printing |
| Answer: 1. Check whether the printing module is damaged 2. Check whether the breakpoint is split 3. Check whether the ink viscosity is normal |
| 41.Saved information will be lost after shutdown and restart |
| Answer: generally, there is a problem with the main board battery. Replace the battery |
| 42.What’s the problem when the ink can’t be filled into the ink core |
| Answer: generally, it is the problem of recovery pump or ink adding valve |
| 43.How to empty ink core |
| Answer: in the system setting, the nozzle throat cleaning is performed, and an empty bottle is placed under the nozzle |
| 44.What can be printed |
| Answer: you can print graphics, text, QR code, database information, pictures, etc. QR code has more than 10 formats |
