What preparations need to be done before using the wall printers, and what maintenance work needs to be done when printing.
1. After turning on the wall printer, check whether the device self-test is successful.
2. Set the necessary parameters in the printing software, mainly including: setting the automatic cleaning frequency, times, mode and flash frequency; printing color bars on the edge of the material; setting the distance of the white edge;
3. After setting the parameters, print the nozzle state diagram, print offset, step offset, and adjust the nozzle and offset value to the best state;
4. Before the official printing, use multiple passes to print a small picture. The advantage of this is that the nozzles can be preheated, thereby increasing the fluidity of the ink.
5. If the heating is on, it is recommended to test the steps first to avoid dimension length issues. Different materials will also have slightly different stretch rates at different temperatures.
