The Epson TX420W 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 TX420W accumulates after cleaning operations. Once it reaches a limit, printing is stopped to prevent overflow.

Why Does the Epson TX420W Show ‘Service Required’?

Most Epson TX420W waste ink counter locks are solved by a software counter reset. Wic Reset Connect provides a straightforward procedure.

How the Error Appears

• 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
