Common Misconception about Using the Ink Pad Counter Resetter Tool
Epson, unlike other brands, includes an ink pad counter chip in its printers. This chip serves a valuable purpose: it helps extend the printer’s lifespan by tracking ink pad usage. However, resetting it using a resetter tool without actually cleaning the ink pad is not a good practice.
The “Service Required” error appears to warn you that the ink pad needs cleaning to prevent messy prints and possible damage to the printhead. Thus, you should clean the ink pad first before resetting the counter chip using the Epson Printer L3150 Resetter.
