Epson L366 Waste Ink Counter Reset

The Epson L366 delivers reliable printing, but periodic maintenance routines can increase the waste ink counter and eventually trigger a ‘Service Required’ lock.

The Epson L366 tracks waste ink with an internal counter. Because it is an estimate (not a physical sensor), it may trigger before the pads are actually full.

Why the Epson L366 Stops Printing (Waste Counter Limit)

With Wic Reset Connect, you can reset the Epson L366 waste ink counter quickly using a Windows PC, USB connection, and a valid reset key.

How the Error Appears

• ‘Service Required’ / service life message in driver or utility
• Maintenance/support code (varies by model/driver)
• Printing stops after cleaning cycles
• Warning repeats after restarting the printer
