Click the "Main" tab. Check the box that says "Clear Ink Absorber Counter." Click "Set." Wait for the status bar to turn green. Do not turn off the printer until the tool says "All operations completed."

  • Launch Service Tool V3.800 as Administrator (right-click → Run as Admin).
  • Select correct USB port (usually appears as "USB001" or similar). If no port shows, the driver or service mode entry failed.
  • Click "Waste Ink Counter Reset" – only this button. Do not touch EEPROM Clear or Destination unless you are a trained technician.
  • Verify reset: Turn printer off normally (Power button), wait 10 seconds, turn on. Error should be gone.
  • Run a test print – if ink leaks, immediately power off and re-check waste pad absorption.
