How to Clean Epson Printhead?

Epson printhead is prone to clogging, so how to clean Epson printhead? With heavy daily use, your Epson printer may experience problems such as blurry prints, inaccurate colors, or the inability to print at all. These problems usually stem from clogged printheads. The printhead is the heart of the printer, and its working quality directly affects the printing effect. Therefore, regular cleaning of the printhead is particularly important. This article will introduce in detail steps to clean the Epson printheads.

Why Are Epson Printheads Easily Clogged?

As a civilian printhead, Epson printheads focus on precision. Common Epson printheads are divided into six-color (six-channel) and eight-color (eight-channel) types. It is different from the two-color (two-channel) common industrial printheads. It can match four common color inks.

  1. Poor ink Quality: Due to the main focus on precision, the diameter of the nozzles on the printhead is 1.5-3.5PL. The nozzle diameter of industrial printheads is 7-35PL. Therefore, it can be seen from this point that Epson printheads have finer particle molecular requirements in ink than industrial ones. Thus, once the wrong ink is selected, it will cause the problem of printhead clogging. To save money, many users often choose to use low-quality ink on the market, which inevitably leads to printhead clogging.
  2. Ink drying: If the printhead has not been used for a long time or the ink quality is poor, the ink will dry on the printhead, causing clogging.
  3. The ink tank is not replaced in time: If the ink tank is used up but is not replaced in time, it will accelerate the drying of the ink and cause clogging.
  4. Low frequency of use: If the printer is not used for a long time, the ink will condense into a solid in the printhead, causing clogging.
