Epson ET-4550 Waste Ink Counter Reset

The Epson ET-4550 delivers reliable printing, but periodic maintenance routines can increase the waste ink counter and eventually trigger a ‘Service Required’ lock.

The Epson ET-4550 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 Does the Epson ET-4550 Show ‘Service Required’?

Most Epson ET-4550 waste ink counter locks are solved by a software counter reset. Wic Reset Connect provides a straightforward procedure.

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
