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

A waste ink counter in the Epson L366 accumulates after cleaning operations. Once it reaches a limit, printing is stopped to prevent overflow.

Why Does the Epson L366 Show ‘Service Required’?

Most Epson L366 waste ink counter locks are solved by a software counter reset. Wic Reset Connect provides a straightforward procedure.

Common Symptoms

• Printer refuses to print even with ink available
• Epson Status Monitor shows maintenance warning
• Blinking lights and blocked jobs
• Device is locked until reset is performed
