KMP E191 Compatible Refill Ink Bottle for Epson 104 EcoTank, Black, 70 ml, up to 4,800 Pages

KMP E191 is a compatible black refill ink for Epson 104 EcoTank printers, supplied as a 70 ml bottle with a stated yield of up to 4,800 pages — for home and office users who want to refill their tank for less than the original bottle costs.

KMP PrintTechnik is a German maker of compatible printer supplies. Article 1648,0001 replaces the Epson 104 black bottle (C13T00P140) and is listed by KMP for more than 45 EcoTank models across the ET-1810 and ET-2700/2800/2900 ranges to the ET-4800. You pour it into the black tank exactly as you would the original bottle.

• 1 × KMP E191 refill ink bottle, Black, 70 ml
• Retail packaging — the printer, other colours and original Epson bottles are not included

• One bottle refills the black tank; 4,800 pages is KMP's stated yield — real output depends on what you print, and photos or full-page graphics use far more ink than text.
• Fill only the black tank and stop at the upper level mark so the tank does not overflow.
• Top up when the level gets low instead of running the tank dry — an empty tank can force a long ink-charging cycle that wastes ink.
• Close the bottle after use and store it upright at room temperature, away from sunlight.

• Epson EcoTank printers that take other bottle numbers (101, 102, 106 or 113) — the bottles are not interchangeable between EcoTank families.
• Cartridge-based Epson printers (Expression, WorkForce cartridge models) — this is bottle ink for ink-tank printers only.
• Pouring it into a tank of another colour — mixed ink cannot be separated and needs a service clean.
• Other brands' tank printers (Canon MegaTank, Brother InkBenefit, HP Smart Tank) — they use their own bottles.
