Canon GI-41 PGBK black ink bottle is now in stock at Mascom International for KSh 2,550, holding 135ml of pigment black ink rated for roughly 6,000 pages. You will find it at our counter in Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD. Every Canon GI-41 PGBK bottle we stock is brand new and sealed, carrying Canon part number 4528C001 and the key-type nozzle that only seats in the black tank. The Canon GI-41 PGBK refills PIXMA MegaTank models including the G1420, G2420, G2460, G3420, G3460, G2470, G3470, and G4470.
Kenyan offices burn through black ink far faster than colour. Accountants printing KRA returns during the June filing rush, law firms copying court bundles for Milimani, schools running end-of-term exam papers, and cyber cafés along Moi Avenue all hit the same wall: the black tank empties first, and printing stops mid-job. The Canon GI-41 PGBK exists for exactly that pattern. One 135ml bottle carries nearly double the volume of each 70ml colour bottle in the same range, so your black supply lasts through the paperwork season instead of running dry halfway through a tender document.
Unlike the unbranded refill syringes sold across Nairobi's back-street counters, the Canon GI-41 PGBK carries Canon's own formulation and a factory seal you inspect before paying. Users consistently report that ink of unknown origin clogs printheads within months, and a printhead replacement often costs more than the printer itself. At Mascom International, we're witnessing steady repeat demand for genuine GI-41 stock from Kenyan schools and small accounting practices that learned this lesson the hard way. Walk into our Kimathi Street counter to collect a bottle, or order for countrywide pay-on-arrival delivery.
Common Questions About the Canon GI-41 PGBK Black Ink Bottle
Which Canon printers does the GI-41 PGBK actually fit?
The GI-41 PGBK fits eleven PIXMA MegaTank models: G1420, G2420, G2460, G3420, G3460, G1430, G2430, G3430, G2470, G3470, and G4470. These are the refillable tank printers Canon sells across Kenya and the wider Middle East and Africa region. If your unit carries a different number, such as a G2411 or a G3411, it takes a different bottle code. Bring the model number printed on the front panel when you visit Kimathi Street and we will match it for you.
How many pages will one bottle actually print?
One 135ml bottle prints roughly 6,000 pages at standard density, or about 7,600 pages in Canon's Economy Print Mode, which lowers black density by around 26 percent. Canon measures these figures using the ISO/IEC 24712 test chart at typical text coverage. Real output shifts with what you print: a page of dense tender tables drains more ink than a short receipt. An office printing 500 pages monthly typically gets close to a full year from a single bottle.
What does printing cost per page with the GI-41 PGBK?
At KSh 2,550 across 6,000 rated pages, black printing works out to roughly KSh 0.43 per page, or about KSh 0.34 per page in Economy Print Mode. Compare that with a typical cartridge printer in Kenya, where a black cartridge costing KSh 3,000 to KSh 4,000 covers 400 to 600 pages and lands near KSh 6 per page. Over the same 6,000 pages, that gap is KSh 2,550 against roughly KSh 36,000.
Is this genuine Canon ink or a repackaged imitation?
It is genuine. Mascom International stocks Canon-branded GI-41 PGBK bottles carrying part number 4528C001, sealed in Canon's own retail packaging. You check the seal, the Canon labelling, and the moulded key-type nozzle before you hand over payment. Kenya's market carries plenty of unbranded fluid decanted into lookalike bottles, and telling the difference becomes impossible once it is poured. Buying over the counter at our Kimathi Street shop, where you inspect the packaging first, removes that risk.
Why does pigment black matter instead of dye ink?
The GI-41 PGBK uses pigment-based black ink, while the matching cyan, magenta, and yellow bottles use dye-based colour ink. Pigment particles sit on the paper surface rather than soaking in, producing sharper letter edges on plain copier paper and text that holds up when a finger or a drop of water hits it. That matters for contracts, receipts, and school reports filed in Kenya's humid coastal counties, where dye-based text can bleed over time.
How do you refill the tank without making a mess?
The GI-41 PGBK uses Canon's no-squeeze bottle format: you invert the bottle into the black tank port and the ink flows on its own, stopping once the tank fills. There is nothing to press, and no syringe or funnel is involved. The nozzle is keyed to a specific shape, so the black bottle physically will not enter the cyan, magenta, or yellow ports. Wipe the tank rim with a dry tissue afterwards and close the cover firmly.
What happens if I pour cheap third-party ink instead?
Non-Canon fluid in a MegaTank printer commonly leads to clogged printhead nozzles, banding across the page, and a grey cast on black text. Canon warranty coverage also excludes damage traced to non-genuine ink, so the repair bill falls entirely on you. Kenyan repair shops charge from KSh 8,000 upwards for printhead replacement on G-series units, and many G1420 and G2420 printers sell under KSh 25,000 new. The KSh 2,550 bottle is the cheaper decision.
How long does an unopened bottle keep in storage?
Canon prints a recommended-use date on each GI-41 PGBK bottle, generally around two years from the manufacture date. Store bottles upright and capped, away from direct sunlight and heat, in a closed drawer or cupboard. Once opened and poured, empty the bottle rather than leaving it part-full for months. Offices in Mombasa, Kisumu, and other warm towns should keep spares indoors rather than in a storeroom that heats up through the afternoon.
Can I get the GI-41 PGBK delivered outside Nairobi?
Yes. Mascom International sends the GI-41 PGBK to all 47 Kenyan counties with pay-on-arrival delivery, so you inspect the sealed bottle before paying the rider or courier. Nairobi and its environs receive the same day. Mombasa, Kisumu, Nakuru, Eldoret, Nyeri, and all other major towns receive it the next business day. Many schools and county offices order four-bottle sets ahead of exam printing, and these travel as one consignment.
Technical Specifications
Ink Formulation and Print Output
- Pigment-based black formulation sits on the paper surface, giving crisp letter edges on ordinary 80gsm copier paper
- 135ml fill volume per bottle, nearly double the 70ml capacity of each matching GI-41 colour bottle
- Rated for approximately 6,000 pages at standard density under Canon's ISO/IEC 24712 measurement method
- Economy Print Mode lowers black density by about 26 percent, stretching output to roughly 7,600 pages per bottle
- Smudge-resistant and water-resistant text survives handling, filing, and humidity across coastal and lakeside counties
- Canon part number 4528C001 identifies the black bottle; colour bottles carry separate GI-41 C, M, and Y codes
Printer Compatibility Across the PIXMA MegaTank Range
- Fits PIXMA G1420, G2420, and G3420 tank printers widely sold through Kenyan retail and office suppliers
- Also fits PIXMA G2460 and G3460 models, including the wireless variants used in small offices and cyber cafés
- Covers the newer PIXMA G1430, G2430, and G3430 units sold across the Middle East and Africa region
- Works with PIXMA G2470, G3470, and G4470 machines, including the G4470 with its automatic document feeder
- Not compatible with GI-51, GI-53, or GI-490 printers; check the code printed inside your ink cover first
- Wrong-series bottles will not seat in the tank port, blocking accidental cross-filling before any fluid is poured
Bottle Design and Refilling Method
- No-squeeze format lets ink flow under gravity and stop automatically once the black tank reaches capacity
- Key-type nozzle shape matches only the black tank port, preventing filling of cyan, magenta, or yellow tanks
- Refilling takes under two minutes with no syringe or needle, unlike aftermarket refill kits sold locally
- Screw cap reseals a partly used bottle, though Canon recommends emptying each bottle into the tank at once
- Transparent tank windows on PIXMA G-series printers show remaining level, so you top up before printing halts
- Bottle stands upright on a desk during pouring, reducing spill risk on shared office desks and school counters
Running Cost and Volume Planning
- KSh 2,550 across 6,000 rated pages puts black printing near KSh 0.43 per page before paper costs
- Economy Print Mode brings that figure to roughly KSh 0.34 per page for drafts, memos, and revision notes
- An office printing 500 pages monthly draws roughly one bottle per year at standard density settings
- A school printing 2,000 exam pages monthly should budget four bottles per academic year plus one spare
- Cartridge-based rivals in Kenya typically cost KSh 5 to KSh 7 per black page at comparable volumes
- Buying two bottles together covers an unexpected volume spike without a second trip into Nairobi CBD traffic
Handling, Storage, and Genuine Verification
- Store upright with the cap closed, away from direct sunlight, heat sources, and the reach of children
- Recommended-use window runs approximately two years from the manufacture date printed on the bottle label
- Sealed retail packaging, Canon labelling, and moulded part codes separate genuine stock from decanted imitations
- Wipe the tank rim with a dry tissue after pouring to keep stray pigment off the printer casing
- Non-genuine ink voids Canon printer coverage on any printhead fault traced to the substituted fluid
- Mascom International staff verify the bottle seal with you at the counter before payment changes hands
