Problems solved by technology

However, in the process of signal transmission, the quality requirements of the line are high, and data loss is prone to occur during the transmission process, or the nozzle control board fails to analyze due to interference in the complex system, and an error will be reported and printing will stop
In this case, the synchronous transmission system is unstable, and some improvements are needed

Embodiment Construction

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the following describes the inkjet printer signal transmission method in the present invention in detail in conjunction with the embodiments and the accompanying drawings, but it is not intended to limit the present invention.

[0023] figure 1 It is a schematic diagram of the corresponding relationship between the printing nozzle and the printing medium in the present invention. During the Onepass printing process, the printing medium is conveyed along the X-axis direction, the position of the nozzle is fixed, and the printing nozzle passes through the printing nozzle at the preset position of the printing medium to be printed. When it is down, the nozzle performs inkjet printing. In order to ensure the correct jetting time of the print head, it is necessary to detect the conveying position of the printing medium during the conveying process, so as to control the print hea...

Abstract

The invention discloses an inkjet printer signal transmission method. A signal is transmitted to at least two spray nozzle control plates through a branched connection plate. The inkjet printer signal transmission method is characterized in that the specific steps of signal transmission include that a, a detection signal is received by an interface in the branched connection plate; b, the detection signal is subjected to latent rule treatment and uneven secondary encoding, and CRC verification treatment is added on the tail of a transmission packet; c, the treated signal is transmitted to the spray nozzle control plates from an output end port in the manner that each channel has two paths; and d, the spray nozzle control plates control spray nozzles to perform printing. According to the inkjet printer signal transmission method, the signal loss can be effectively avoided due to the data transmission manner of the branched connection plate, it is avoided that signal analysis of the spray nozzle control plates fails, the anti-interference capacity is improved, the transmission reliability is improved, and therefore inkjet of a plurality of spray nozzle modules is controlled, the using field is widened, and the inkjet quality is guaranteed.

Description

technical field [0001] The invention relates to a signal transmission method of an inkjet printer, in particular to a signal transmission method of an inkjet printer which distributes detection signals to a plurality of print nozzles at the same time and ensures stable signal transmission. Background technique [0002] Inkjet printers can be divided into two types according to the way of printing graphics and texts. One is to spray graphics and texts with the reciprocating motion of the nozzle; the other is to spray graphics and texts in a way that the nozzle does not move and the printing medium moves, that is, the Onepass method, and the printing is usually variable. This type of inkjet printer is used for data such as barcodes and receipt information. The Onepass printing speed is very fast, and can reach a printing speed of 200m / s or faster, while ensuring high printing quality, and the printing resolution can reach 600dpi. In this high-speed printing process, the graph...
