A: Indefinitely, but after 2–3 resets (about 50,000 pages), the pads will be fully saturated. You must replace them or install an external waste tank.

  • Best for: First-time users; requires no additional drivers.
  • What is an adjustment program?
    It's a service utility that resets the printer's waste ink pad counter after it reaches its limit (usually after ~8,000–15,000 prints). The printer will show "Service required" or blinking lights without this reset.

    Using free unofficial "adjustment programs" carries significant security, warranty, and reliability risks; contacting Epson or an authorized repair service is the safest route.
