Published by March 19,2024

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.

 

Epson print head

 

1. Epson print head


The Epson print head in Japan has always been an independent leader in the era of Japanese photo machines.

The service life is less than 1.5 years.

 

3. Ricoh print head

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.
