Do you have many questions about dx5 printheads used in flatbed/UV printers?
Are you often unable to differentiate between DX5, DX7 and DX10? Actually, DX* is just the Chinese printer manufacturer's name, not the model name of the dx5 printhead. DX5 head used in general flatbed/UV printers mainly include R1390 and R1900 models:
Difference between Epson R1390 and R1900:
The R1390 has 6 ink channels, 6 rows of nozzles, 90 holes in a single row and a total of 540 nozzle holes.
The R1900 has 8 ink channels, 8 rows of nozzles, 180 holes in a single row and a total of 1440 nozzles with a minimum of 3.5PL/5PL. As a result, the R1900's printed color display is more vivid and faster than the R1390's.
Therefore, the price of the R1900 has also been high, about 5 times that of the R1390. Also, because Epson DX5 printheads have been out of production for over a decade now, there are fewer and fewer original printheads in the actual distribution market. Many manufacturers claim that this printer uses the original DX5 printhead. In fact, many of them are used printheads with inconsistent print quality and inconsistent lifespan.
Therefore, when buying a printer, you need to pay attention to the following points:
1. Make sure to ask for the model number of the printhead, not the DX.
2. Don't covet cheap prices. The cheaper the printer, the more likely it is to be refurbished, or to use used printheads and low-cost machine accessories. In this way, the machine often cannot be used for a few days, and even the cost of the machine cannot be recovered.
3. Choose a brand printer manufacturer, you can search for manufacturer information on Google, request a video call inspection with the manufacturer, ask the manufacturer to show the relevant inspection certificate, or have a third-party inspection certificate (such as Alibaba's factory inspection) Certificate.
