Cyber cafe operators, school bursars, church administrators, small print shops, accountants preparing KRA and ETIMS paperwork, and university students printing coursework all reach for the Epson 103 EcoTank Yellow Ink Bottle when colour output starts fading. Yellow usually empties first in offices that print logos, certificates, invoices with coloured letterheads, and marketing flyers. When the yellow tank runs low, an EcoTank printer stops producing accurate greens, oranges, and skin tones, and many models refuse colour jobs entirely. Keeping one spare bottle on the shelf costs far less than losing a printing afternoon.

Third-party refill ink sold cheaply around Nairobi often thickens inside the print head, and clearing a blocked head costs more than several bottles combined. The Epson 103 Yellow Ink Bottle carries Epson's own formulation and the keyed nozzle that only fits the yellow tank, so nobody in your office can pour it into the wrong chamber. Buyers throughout Kenya tell us that switching back to genuine bottles ended their repeat nozzle-cleaning cycles. Walk into our Nairobi CBD shop to check the Epson authenticity label yourself, or order for pay-on-arrival delivery to any county.

Every unit Mascom International sells is a genuine Epson consumable carrying part code C13T00S44A on the bottle and the carton, with Epson's holographic authenticity label intact. Regional stock also appears as C13T00S44A10, which is the same 65ml yellow formulation in Epson's Western Europe packaging. We do not stock compatible clones, syringe refills, or decanted bulk ink. You can inspect the seal, the code, and the label at our Kimathi Street counter before paying, or check them on arrival if you order for delivery.

The Epson 103 series covers most four-colour EcoTank models sold in Kenya, including the L1110, L3110, L3111, L3150, L3151, L3156 and L3160. It also fits the newer L1210, L1250, L3210, L3211, L3250, L3251, L3256, L3260 and L3266, plus the office-focused L5190, L5290, L5296, L5310, L5316, L5590, L3550 and L3560. Owners of the A3 L11050 use the same bottles. Check the label beside your printer's ink tanks: if it reads 103, this bottle is correct.

Epson rates the 103 colour bottles at up to 7,500 pages each, measured from ISO/IEC 24712 test pattern simulations rather than ISO/IEC 24711 cartridge testing. Real Kenyan output depends on what you print. Text documents with a small coloured logo stretch a bottle well past a year in a home office. Full-page flyers, photographs, and certificate borders consume yellow far faster, sometimes emptying a tank within a few thousand sheets. Treat 7,500 as a ceiling, not a promise.

At KSh 2,300 for up to 7,500 pages, the yellow component of a colour print costs roughly 31 cents per page at Epson's rated coverage. A full four-colour set at Mascom International pricing keeps a typical colour page under KSh 1.50 in ink. Compare that with laser toner refills around Nairobi, where colour cartridges routinely run KSh 4,000 upward for a few thousand pages. That gap is why cyber cafes on Moi Avenue and Tom Mboya Street standardised on EcoTank hardware.

No. Epson redesigned the 103 bottles with a keyed nozzle and a matching tank collar, so the yellow bottle physically will not seat in the black, cyan, or magenta openings. The bottle also self-stops once the tank fills, which prevents the overflow that used to soak desks during syringe refills. Staff who have never refilled a printer manage it on their first attempt. Keep the cap for storage, wipe the nozzle with tissue, and no ink reaches your hands.

Yes, and this surprises many Kenyan buyers. EcoTank printers periodically fire small amounts of every colour through the print head during maintenance cycles, whether or not you print in colour. Letting the yellow tank sit empty allows air into that channel, and the resulting blockage often needs a paid head cleaning at a service desk. Most models also refuse to start any job when a tank reads empty. Topping up yellow protects the print head you already paid for.

Each Epson bottle series matches specific printer generations and they are not interchangeable. The 664 range serves older L120, L220, L360 and L565 units. The 003 range covers L3110-family printers sold in some Asian and African markets, and the 008 range feeds the higher-capacity L6000 and L15000 series. Fitting the wrong series risks colour shifts and warranty disputes. Read the number printed beside your tanks, or send us a photo on WhatsApp and our team confirms it.

Keep unopened bottles upright, capped, and out of direct sunlight, ideally below 30 degrees Celsius. Nairobi and upcountry conditions suit ink storage well, though Mombasa and Kisumu offices should avoid leaving stock on windowsills or inside hot store rooms. Epson recommends using ink within six months of opening a bottle for consistent colour. Note the safety warning on the carton: the formulation contains preservatives that can trigger allergic skin reactions, so keep bottles away from children.

The Epson 103 EcoTank Yellow Ink Bottle from Mascom International arrives as a factory-sealed retail carton containing one 65ml bottle with its keyed nozzle and screw cap, the Epson authenticity label, and the printed handling and safety leaflet in English. No funnel, gloves, or syringe ships with the bottle, and none are needed because the nozzle seats directly into the printer tank. Ask our counter staff for a matching black, cyan, or magenta bottle if you are refilling a full set.

Ink is a consumable, so it carries no period-based hardware warranty. Mascom International guarantees that every Epson 103 bottle we sell is genuine and factory sealed, and we replace any bottle that reaches you leaking, damaged, or with a broken seal. Report such a unit within seven days of receipt and our Nairobi CBD service desk handles the swap directly.
