Why the UV flatbed printer print head occur heating does not heat up?
UV flatbed printer print head heating does not heat up, it will directly affect the normal ink out of UV ink, leading to ink cut-off during printing. Especially when the temperature in winter is low, the fluency of UV ink is far less than that in summer. At this time, not only the equipment nozzles and UV ink need to be heated, but the external working environment also needs a suitable temperature. The suitable ambient temperature for UV flatbed printers is between 15° C and 25° C, and the humidity is between 40% and 70%. There are 6 kinds of reasons that the nozzle does not heat up, and it is easy to solve.
1,Heating sheet aging
This is a normal phenomenon. The heater of the UV flatbed printer print head has been working for a long time. Generally, after 6 months, aging will occur. Replace the new heater.
2. The machine is not reset
Reset the UV flatbed printer and turn it on again, so the heating plate will heat up.
3. Poor heating contact
Check whether the contact between the heating plate and the nozzle line is loosened or broken. If it is, it can be restored after reconnecting.
5. Poor thermal conductivity of heating plate
If the screw between the heating plate and the UV flatbed printer nozzle is loosened, which causes the gap to become larger, or there is a foreign object in the heat conduction area, clean it in time and tighten it together.
6. Nozzle board malfunction
After checking the above five conditions, if the heating plate does not heat up, it means that the nozzle board is faulty. Contact the manufacturer and send a new nozzle board to replace it.
It should be noted that when the weather is cold in winter, before UV flatbed printers start printing, be sure to heat the UV ink, nozzles and other key parts before printing. If it is an old device, there is no heating plate or built-in circulating heating For the system, you may wish to purchase air conditioner.
