• Cause: The physical waste ink pad may be truly saturated, triggering a hardware short.
• Fix: You cannot reset your way out of a physical overflow. You must open the printer, remove the pad, wash it, dry it, or replace it with a diaper pad or paper towel layer. After physical cleaning, run the service tool reset again.

Crucially, your printer does not have a physical sensor to detect when the pad is full. Instead, it uses a software counter. Every time the printer purges ink, it increments an internal log. Once this counter hits a pre-programmed limit (e.g., 5,000 or 10,000 purge cycles), the printer locks up with an error code. PIXMA G Series: G1400, G2400, G3400, G1401, G2401,
