Whether it is a laser printer or an inkjet printer, it is always "squeaky" in front of the normal operator. during operation, if it is slightly inadvertent, there may cause different problems, which is troublesome. If we pay attention to some details, we can avoid some troubles; in addition, proper control of some operations can also greatly improve printing efficiency.
6 tips for you below:
1, when moving your uv printer, be careful not to carry the printing platform to move, to lift the bottom of the machine or slightly up the sheepskin. There is just one part at the bottom of the leather that can hold the case with both hands to move the uv printer.

In addition, when adding ink Note that add ink to the external ink cartridge 2/3, not too much.
3，Printer height adjustment. Generally, the uv printer in the market mainly detects the height of the object by infrared rays.
