Japan Seiko printheads are industrial printheads with aluminum alloy casings. They entered the Chinese market in 2009. They are an early industrial printhead. The advantage is that they are more durable than Epson, with a lifespan of 1-2 years, industrial grade, and faster inkjet speed. The disadvantage is that the precision is low, the price is high, the single head is monochrome, and it must be equipped with 5-7 heads, or 10 heads. Compared with Ricoh, Seiko belongs to the early nozzles.
