Technical Field

[0001] The utility model relates to the technical field of inkjet printers, in particular to an intelligent height measuring device for inkjet printers. Background Art

[0002] Inkjet printers turn colored liquid ink into tiny particles through nozzles and spray them onto printing paper. Some inkjet printers have three or four print heads to print yellow, magenta, cyan and black; some share one print head for four-color printing. There are two main technologies used in inkjet printers: continuous inkjet technology and random inkjet technology. Early inkjet printers and current large-format inkjet printers all use continuous inkjet technology, while popular inkjet printers on the market currently generally use random inkjet technology. Continuous inkjet technology is represented by charge modulation type. In the random inkjet system, ink is only sprayed when printing is needed, so it is also called on-demand.
