| Q2.The machine interface displays the mixed cylinder empty Icon? |
| Answer： 1. Check whether the pipeline system leaks ink and whether the ink adding valve is blocked. |
| Q3.Charging fault icon is displayed on the machine interface? |
| Answer: check if the viscosity is normal. Check if the viscosity is normal. Check how the breakpoint splits. If it is normal, replace the ink. The ink may deteriorate |
| Q4.The machine interface displays the recycling fault Icon? |
| Answer: check whether the ink line of the nozzle enters the recycling tank. If not, adjust the ink line to the recycling tank to enter the recycling tank without recycling. If the recycling pipe is blocked, check the recycling pipe |
| Q5.The machine interface displays the high voltage fault Icon? |
| Answer: the high pressure deflector accumulates ink, cleans the high pressure deflector, and checks whether the ink viscosity and breakpoint splitting are normal |
| Q6.Error icon of solvent box is displayed on the machine interface, unable to identify? |
| Answer: no solvent box or solvent box is not inserted in place |
| Q7.Ink box error icon displayed on machine interface, unrecognized? |
| Answer: the ink box without ink box is not inserted in place |
| Q8.The machine interface displays the mixed cylinder overfull Icon? |
| Answer: discharge some ink from the ink core until the alarm icon disappears |
| Q9.The machine interface displays the synchronizer too fast Icon? |
| Answer: you can increase the font width or reduce the number of vertical lattice or reduce the number of synchronizer speed to eliminate this warning |
| Q10.Viscosity fault icon on machine interface? |
| Answer: the viscosity of the ink in the mixing cylinder is too low or too high. The ink line can be started to circulate until the ink viscosity is normal. |
| Q11.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 |
| Q12.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 |
| Q13.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 The charging is not good and the ink is out of date |
| Q14.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 |
| Q15.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 |
| Q16.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 |
| Q17.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 |
| Q18.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 |
| Q19.Encoder mode word width setting? |
| Answer: choose the right word width according to the customer’s requirements, generally 1 to 10, 1 represents the fastest speed |
| Q20.Where to look in the diagnosis interface? |
| Answer: press the I key in the lower left corner of the keyboard to view |
| Q21.What is the advanced code of inkjet printer? How to input? |
| Answer: press F4 to input 9999 directly, and then press enter |
| Q22.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. |
| Q23.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 |
| Q24.Ink points are not well split? |
| Answer: 1. Adjust modulation voltage 2. Replace crystal oscillator voltage 3. Ink quality problem |
| Q25.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 |
| Q26.Saved information will be lost after shutdown and restart? |
| Answer: generally, there is a problem with the main board battery. Replace the battery |
| Q27.The model temperature is too high? |
| Answer: 1. Check whether the temperature of the model is too high 2. The fan is damaged 3. The main board is damaged |
| Q28.Where is the modulation voltage adjusted? |
| Answer: press F4 to input the advanced code 9999, and then select m > modulation voltage in the machine settings to adjust |
| Q29.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 |
| Q30.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 |
| Q31.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 |
| Q32.What is the actual height of the minimum and maximum typeface that can be printed on the microtypewriter? |
| Answer: minimum (5 dot matrix) height 0.08mm maximum (34 dot matrix) height 10mm |
