The print head is the core component of inkjet printing equipment. In the application of inkjet printing equipment such as photo printers, inkjet printers, and UV flatbed printers, the print head plays a key and important role. Its technology and printing accuracy determine the inkjet printing. The print quality of the printing device.

In large-format printer equipment, our more common print heads are Epson series piezoelectric print heads, Ricoh print heads, and Konica print heads. This article focuses on sharing these three common print heads.

1. Epson print head

The Epson print head in Japan has always been an independent leader in the era of Japanese photo machines. EPSON print heads can be seen in MIMAKI, ROLAND, MOUTH, and other series of Japanese photo machines. At present, domestic equipment has also begun to use EPSON's DX5 on a large scale to take the lead in the development of domestic production. photo inkjet printer.

2. Konica print head

The Konica print head is a double-row ink inlet tube with a uniform flow and pressure to ensure print quality. Some brands are single row. The 512 Konica print head is a fully enclosed print head, waterproof and anti-aging. Konica printheads have poor compatibility with inks, have strict requirements for inks in different seasons, are sensitive to changes in ambient temperature, and the printheads are exposed. The service life is less than 1.5 years.

3. Ricoh print head

Ricoh print heads are mainly used in high-end industrial UV printers. Most of the machines imported from abroad use Ricoh print heads. The same industrial print head machine, Ricoh's printing effect is relatively good and clear, and can basically achieve the printing effect of Epson. Double-row ink inlet tube, fine ink dots, grayscale printing. A fully enclosed print head, waterproof and anti-aging Ricoh Gen4 print head has a built-in constant temperature system, the printing voltage is adjusted with the temperature, and a more stable printing state can be obtained. The circuit board of the print head is all metal wrapped, which can soak the ink without causing damage to the print head. The print head has a long life and can be used for 3-5 years normally. It is the most successful piezoelectric print head. The single print head, single-color control, all-steel structure, super corrosion-resistant print head, both speed, and effect, but its disadvantage is that the price is more expensive than other types of print head machines.
