From 2003 to 20 10, the growth rate of Epson stylus printer market share exceeded 10%, and the main force of the growth was 80-column flat-push stylus printing dedicated to printing national tax and local tax invoices. 20111October, the output of Epson's 80-column flat-push bill stylus printer exceeded 3 million.
As the inventor of the stylus printer, Epson has a large number of stylus printer patents, with a total of 76 patents. At present, the print head life of Epson stylus printer can reach 400 million times per needle. According to the calculation of 24 dots per character, a 24-pin printhead can print 400 million characters. According to the calculation of 40 characters per line, 6.5438+million lines can be printed. According to a 20 cm line, 2000 km of characters can be printed, which is equivalent to the distance from Beijing to Fuzhou.
Epson needles always follow the three noes, that is, do not accept, do not manufacture and do not flow out. Not accepting means not accepting defective parts. Epson requires parts suppliers to provide parts that meet Epson's requirements, and parts suppliers should conduct spot checks on parts frequently. After the parts arrive at the factory, they should not be produced first, but should be tested before production.
During the testing process, Epson used a variety of equipment for testing, including three-dimensional, projector, microscope and laser caliper. It is worth mentioning that the resolution of three-dimensional measurement can reach 0.5 micron, so that no flaws will be hidden.
Not manufacturing means not manufacturing defective products in the production environment. Epson requires workers to carry out independent inspection and mutual inspection in the production process, and adopts a foolproof design in the production process, and sticks bar codes on all parts to facilitate recording the production process of products.
What is worth mentioning is the foolproof design. The number of parts provided by workers in the assembly process is the same as that required. If there are spare parts after assembly, it means that there are omissions during installation and workers need to check them. In addition, 100% internal and external inspection, 100% safety inspection and 100% printing inspection are required after production.
No outflow means that products with quality problems are not allowed to flow out of the workshop. After the printer has undergone routine inspection, the quality control department will also conduct random inspection of the products, and the products that have been sampled will be tested for durability at room temperature and high temperature, as well as environmental protection and safety.
The durability test at room temperature is used to confirm whether there are fatal defects in the basic performance of the product. Identify potential quality problems that cannot be detected in routine inspection, such as short-term deterioration, failure, breakage and abnormal wear. High and low temperature durability test refers to printing at the upper and lower limits of 5℃~35℃ according to the temperature environment required by the product instruction manual to confirm the printing resistance and printing effect of the product at extreme temperature.
Environmental testing refers to the method of measuring the power consumption of products in accordance with regulations and regularly confirming that products meet the requirements of energy-saving indicators. It is worth mentioning that all the needles of Epson have passed the certification of energy efficiency label 1, and the energy consumption is 0 in standby state and 1.5w in working state.
Safety inspection refers to the chemical composition analysis of parts used in production. Epson uses XRF analyzer to measure lead, mercury, cadmium, chromium and other elements in plastic parts, packaging materials, metals, galvanized products, fast-cutting brass, fast-cutting aluminum and solder parts to ensure that the products meet RoHS requirements.
