The Epson L405 is one of the best multifunction printers designed for everyday printing needs, whether at home or in a small office. The printer is equipped with modern features, including Wi-Fi Direct, Epson Connect, and the EcoTank ink system, which is known for being efficient, cost-effective, and environmentally friendly. With this technology, users can print documents or photos directly from their mobile devices without needing additional cables.
However, over time and with high intensity of use, users often face some common problems that prevent the printer from operating normally. Among them:
- A “Service Required” message appears on the computer screen or printer panel.
- The printer stopped working suddenly because the Waste Ink Pad Counter had reached the maximum limit.
- The indicator light flashes simultaneously, indicating an error in the ink disposal system.
The problem does not indicate physical damage, but rather the internal system of the printer that needs a reset in order to return to function.
Many users try the manual method, but these steps are often ineffective or even cause additional errors.
For this reason, the best solution is to use the Epson L405 Adjustment Program, which is an official software specifically designed to reset the Waste Ink Pad Counter safely and accurately.
The program has proven effective based on the experience of professional technicians in the field, who for many years have handled different types of Epson printers.
