## Why Proper Refilling Matters

→ Ensures consistent ink flow and prevents gaps or streaks in your prints→ Reduces the chance of air entering the ink lines, which can clog nozzles→ Keeps ink‐level sensors accurate so you always know when to top up

—

## Step-by-Step Refill Procedure

→ Power off your Epson EcoTank printer and open the ink tank cover→ Remove the cap from the correct ink bottle and align it with the matching fill port→ Squeeze the bottle gently until the ink flow stops—do not overfill→ Replace the bottle cap and securely close the ink tank cover→ Turn the printer back on and check ink levels via the control panel

—

## Common Mistakes to Avoid

→ Overfilling tanks, causing ink to spill inside the printer→ Shaking bottles vigorously, which introduces air bubbles→ Refilling under poor lighting and placing ink in the wrong tank→ Using non-genuine inks that may not seal properly or flow consistently

—

## Priming Your Ink System

→ Run a printhead cleaning cycle from the printer’s menu after refilling→ Print a nozzle check pattern and look for any missing lines or gaps→ Repeat cleaning cycles as needed until the pattern is solid→ Top up ink before levels drop too low to avoid drawing in air
