Additional low-cost ink can be bought in a convenient high-volume bottle that has a drip-free nozzle and resealable cap for easy storage and refilling. We have redesigned our ink bottles to incorporate a unique key system to ensure more precise refilling to avoid spillage. The ink bottle also incorporates a pressure mechanism so the bottle automatically stops exerting ink once the ink tank is full. Replacement bottles hold enough ink for a massive 6,000 pages in black. The ET-M1100 is designed for small spaces. Its compact footprint means you can fit it comfortably anywhere in your home or home office, creating an ergonomic work environment.
