Digital printing machine as a highly sophisticated and expensive textile printing production equipment, plays a vital role, which printing print-heads as the core component of digital printing machine, its performance and life directly affect the quality and efficiency of printing. The overall structure of the digital printing machine and many parts can enjoy the quality assurance services provided by the manufacturer, but the print-heads is often not within the scope of conventional warranty, why the digital printing machine print-heads is not guaranteed?
First of all, digital inkjet printing equipment such as digital printing machines are very sophisticated mechanical and electronic equipment, especially the print-heads production process is very fine. Take the Ricoh print-heads of BYDI mainstream as an example, the diameter of the spray hole is only about 0.677mm, which can not be seen by the naked eye. As a result, very fine dust can clog the spray hole, and fingernails can often easily damage the surface of the print-heads. Due to the current technical limitations, the surface of the print-heads is exposed to the outside, so improper human operation is easy to cause damage to the print-heads, and many man-made manufacturers cannot be identified in the printing production process.
Secondly, many people buy equipment without the original printing ink provided by the manufacturer, and the ink is also the main reason that the print-heads is often blocked, scrapped, and the service life of the print-heads is reduced. The production of ink also has many technical indicators: PH, precipitation ratio, concentration, chemical stability and so on. There is no shortage of cheap ink on the market, and these inks are very low in the friendliness of the equipment print-heads, which is likely to greatly reduce the service life of the print-heads, and the manufacturer can not guarantee that the person who buys the equipment has been using the original ink, so the manufacturer generally does not provide warranty for the print-heads from the ink use.To be continued, please consult:
