Critical Refill Reminder: Avoid Air Trapping

When manually pouring your 664 ink bottle into the tank reservoir, ensure the printer is turned off. Do not squeeze the bottle aggressively; allow gravity to drain the fluid to prevent creating excessive micro-air bubbles in the internal ink lines, which can cause temporary faint lines or print gaps.
