How to choose print heads for UV printer?

Nowadays, UV printer heads in the printing market, like Epson, Kyocera, Konica, Ricoh are generally the most common brands. Nozzle life, Accuracy, Stability these factors directly affect the use of subsequent equipment. The core is to look at the price of the nozzle, cheap nozzle is not as good as an expensive one. In fact, there are lots of customers who are not particularly understanding of the nozzles, so here will popularize some of the UV printer nozzle tips for everyone.

1. Epson printhead

As we all know, Epson nozzles have been independent in the era of Japanese inkjet printer. Epson print heads we mainly see in Japanese series machines such as Mimaki, Roland, Mutoh, etc. At present, domestic inkjet printer has also begun to use Epson DX5 to take the lead. Besides, with the development of domestic inkjet printers, indoor and outdoor piezoelectric wide format printers are all high-performance and high-precision Epson DX5 piezoelectric nozzles.

2. Konica print head

Konica nozzles are double-row ink tubes with uniform flow and pressure. Ensure print quality. Some brands are single row. The 512 Konica printhead is a fully enclosed printhead, waterproof and anti-aging. Konica nozzles have poor ink compatibility and strict requirements for inks in different seasons. They are sensitive to environmental temperature changes. The nozzle plate exposes, and the ink will burn the nozzles. It is easy to break the ink at high and low temperatures. Use Life expectancy is less than 1.5 years.



3. RICOH print head:

Ricoh nozzles are mainly suitable for high-end industrial UV printers. Like most of the one or two million machines imported abroad, using  Ricoh print heads. With the same industrial printhead machine, Ricoh’s printing effect is definitely the best, the clearest, and can basically achieve the printing effect of Epson. Double-row ink tube with fine ink dots and grayscale printing fully enclosed nozzle, waterproof, anti-aging Ricoh Gen5 nozzle has a built-in constant temperature system, the printing voltage is adjusted with the temperature, then achieving a more stable printing state. The circuit board of the nozzle is all metal, so it can be soaked in ink without causing damage to the nozzle. The life of the nozzle is long, and it can be used normally for 3-5 years, so we think this is the most successful piezoelectric nozzle. The single-color control of a single nozzle, the all-steel structure super corrosion-resistant nozzle has both speed and effect, but its disadvantage is that the price is more expensive than other types of nozzle machines.

How long does the UV flatbed printer print life last?

Epson UV flatbed printer print head life of about 1 year, industrial print head UV flatbed printer print head life of 1 to 2 years. Refers to the natural life of the nozzle under normal maintenance conditions, that is, the life of the print head in the case of damage caused by non-human factors.

UV flatbed printer nozzles are divided into industrial nozzles and non-industrial nozzles. Non-industrial nozzles mainly refer to non-metallic nozzles. Common Epson nozzles, Ricoh GH2220 nozzles, industrial nozzles mainly refer to all-steel nozzles, such as Ricoh G5, Seiko , Toshiba, Kyocera, etc.

Non-industrial nozzle UV flatbed printer nozzle life: Common UV flatbed printers Non-industrial nozzles are mainly the following, Epson five generations, Epson ten generations, Epson 4720, Ricoh GH2220, the life of these nozzles is generally about one year, especially Remember: Ricoh GH2220 is not an industrial nozzle, GH2220 is commonly known as small Ricoh, and big G5 is a real industrial nozzle.

UV flatbed printer nozzle life of industrial nozzles: Common industrial nozzles have the following defects: Ricoh G5, Seiko, Toshiba, Konica, Kyocera, if these print heads are well maintained, it will not be a problem for 2 years. Zhongliguang G5 is more common, and other nozzles are relatively small. Toshiba has developed well in recent years, but the gap with Ricoh G5 is still relatively large.
