How does autostop and keyed design make refilling easier?

The bottle’s keyed neck matches only the black tank port, helping prevent cross-contamination and accidental color swaps. Autostop technology halts flow when the tank is full, reducing overfills and mess. This combination is designed for straightforward, low-fuss refills even for first-time EcoTank users.

• Keyed nozzle prevents inserting into the wrong tank
• Autostop stops ink flow automatically when full
• Wide mouth and ergonomic bottle shape for stable pouring

What can I expect for page yield and cost savings?

Yields are measured using the ISO/IEC 24712 test pattern and will vary with print settings, image coverage, and environmental factors. Epson’s replacement bottles are designed to provide thousands of pages per bottle under typical conditions, which often lowers cost per page versus cartridge-based systems.

• Yields depend on content, settings, and usage frequency
• Potential for large savings compared with standard cartridges
• All colors are used for printing and maintenance—keeping all bottles available helps maintain performance
