Many people will worry about the problem that "the metal sign UV printer will block the nozzle if it doesn't print for a long time". In fact, it's not difficult. You just need to do regular maintenance on its nozzle. Do you know what to do?

1. When using metal sign UV printer in winter, it can be blown with an air duct before starting up every morning;

2. If the indoor environment is cold or too dry, cover the machine with a large and thick cloth, and remember to cover the paper inlet and outlet;

3. Start up and check the nozzle at least once a week;

4. At ordinary times, you can open the upper cover of the metal sign UV printer when it is turned off, and you can see that there is a relatively smooth iron rod lying across it, that is, the guide rod. We can point a few drops of precision lubricating oil on it and try to remove the original dirt on the guide rod.
