Description

Technical Field

[0001] The utility model relates to the technical field of laser printing, in particular to a high-precision laser printer. Background Art

[0002] Laser printing technology uses laser beams to quickly "project" digital graphics or documents onto a photosensitive surface (photosensitive drum). Electron discharge occurs at the location hit by the laser beam, and then due to static electricity, some fine "toner" is attracted like a magnet, and the printing effect is produced. Because its core printing technology is laser imaging technology, this printing technology is called "laser printing technology."

[0003] Patent announcement number CN206436648U discloses a laser digital printer for ceramic tiles with a high-precision positioning function, including a main box, a main platform, a working platform, a side bracket, an ink cartridge, a laser printing head and a USB interface. The main box is provided with a main platform at the upper end, and slide rails are provided on both sides of the main platform. The upper end of the main platform is provided with a working platform, and the slide rail is connected to the side bracket through a slider. The ink cartridge is provided on one side of the side bracket, and the upper end of the side bracket is provided with a Y-axis slide rail, and the lower side of the Y-axis slide rail is provided with a Y-axis slider.
