1. Introduction The Epson EcoTank L3250 is a popular all-in-one ink tank printer known for its low running costs. However, like all Epson inkjet printers, it contains a built-in waste ink counter. This counter tracks the amount of ink flushed through the printer during cleaning cycles. Once this counter reaches a preset limit (usually around 70-80% of the waste pad’s capacity), the printer will stop working and display a "Service Required" error (e.g., "Parts inside your printer are at the end of their service life").
