How Epson Inkjet Printers Work

Different inkjet printers work differently depending on the technologies used by the manufacturer. The details about the operation of printers are usually confidential. Manufacturers need to protect their data from competitors. However, if you’re trying to learn as much information about Epson printers and Epson Expression XP-400 cartridges as you can, here’s a general overview of how it works.

Overview

Epson printers usually come with features that you can’t find in any other inkjet printer. One of its most unique features is the piezoelectric-driven printhead. This printhead drives the ink towards the microscopic nozzles. It is usually implemented outside the Epson Expression XP-400 cartridges, thus making it more accurate yet expensive.

A crystal located at the back of each nozzle’s ink reservoir receives an electric shock and vibrates inward. Doing so forces the ink out of the nozzle.

Printer Maintenance

Since Epson uses an ink cartridge that’s a fixed part of the printhead, when the printhead gets stuck, you’ll be facing a big problem. You can’t replace it easily. The best thing you can do is to avoid damaging it.

Normally, you need to keep the ink channel and nozzles soaked or full of fresh ink. Otherwise, they will dry out or rust. Epson recommends that you use your printer at least once a month.

It is also necessary that you turn off your printer by pressing the power button. Do not pull the plug suddenly. The printhead uses a special parking position that allows it to stay stationary for weeks without getting dry.

Conclusion

Like any other printers, Epson Inkjet printer needs to be properly maintained. If there are damages that you can’t repair yourself, contact an Epson technician.
