Canon BH-4 Black Print Head is now in stock at Mascom International for KSh 5,150, brand new and sealed in Canon retail packaging under part number 0691C002AA. This is the black printing unit for Canon PIXMA G-series refillable ink tank printers, covering the G1400, G1410, G1411, G1416, G2400, G2410, G2411, G2415, G3400, G3410, G3411, G3415, G4400, G4410, and G4411. The Canon BH-4 Black Print Head carries 1,280 nozzles firing 2-picolitre droplets, and it drops into the carriage by hand in under five minutes. Collect it from Mascom International at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD.
Kenya's small offices, cyber cafes, schools, and print bureaus lean hard on Canon G-series ink tank machines because refill bottles cost a fraction of cartridge pricing. The trade-off is volume, and volume eventually wears the nozzle plate. When black text starts arriving with white bands, missing rows, or nothing at all after repeated deep cleaning cycles, the head is the fault and not the ink. A Canon BH-4 Black Print Head keeps a working machine in service for KSh 5,150 rather than forcing a full printer replacement. Accountants filing KRA returns, clinics printing patient notes, and schools running exam papers avoid days of downtime.
Unlike other electronics retailers in Kenya, Mascom International stocks the Canon BH-4 Black Print Head alongside the matching CH-4 colour unit, so buyers who need both leave with a complete pair the same day. Our team at Mascom International tracks which G-series models arrive at Nairobi CBD repair benches most often, and the G2411 and G3411 lead by a wide margin. Users consistently report that a fresh head clears banding that six or seven cleaning cycles could not touch. Walk into the Kimathi Street shop to check your printer model against the Canon BH-4 Black Print Head before paying, or order for countrywide delivery.
Common Questions About the Canon BH-4 Black Print Head
Which Canon printers does the Canon BH-4 Black Print Head fit?
The Canon BH-4 fits Canon PIXMA G-series ink tank printers: G1400, G1410, G1411, G1416, G2400, G2410, G2411, G2415, G3400, G3410, G3411, G3415, G4400, G4410, and G4411. These are the refillable-tank models sold widely across Kenya between 2016 and the present. Check the model badge on the front panel before ordering. Newer G-series machines such as the G2420, G3420, G5040, G6040, and G7040 use a different head and are not covered by this part.
How do I know the print head failed and not the ink?
Run the printer's nozzle check pattern from the maintenance menu. If the black grid prints with missing lines, white gaps, or comes out blank while the tank still holds ink and the tube shows no air bubble, the head is the problem. Two or three deep cleaning cycles should recover a clogged head. If the pattern stays broken after that, replacement is the fix. Colour printing that still works normally points squarely at the black unit.
Is the Canon BH-4 the same as the CH-4 colour unit?
No. They are two separate parts that sit side by side in the same carriage. The Canon BH-4, part number 0691C002AA, handles pigment black for text and documents. The CH-4, part number 0694C002AA, handles cyan, magenta, and yellow for photos and graphics. A printer with faded colour but sharp black text needs the CH-4 instead. Mascom International stocks both, so bring your printer details and we will match the correct one.
Can I fit the Canon BH-4 print head myself?
Yes. Canon designed this part for owner replacement, which is why it sells separately instead of requiring a service depot visit. Power the printer on, open the top cover so the carriage moves to centre, lift the lock lever, remove the old unit, peel the protective tape and orange cap from the new one, seat it firmly, and close the lever. The printer then runs an alignment routine. The whole job takes roughly five minutes.
How many pages does the Canon BH-4 print head last?
Retailer figures put working life at roughly 3,000 to 7,000 pages, with the spread driven by page coverage, ink quality, and how often the machine sits idle. Dense graphics and heavy text pages wear nozzles faster than light correspondence. Printers used a few times weekly outlast printers left switched off for months, because settled ink dries inside the nozzles. Printing at least a few pages every week is the cheapest way to stretch this figure.
Is KSh 5,150 worth it against buying a new printer?
A replacement PIXMA G-series ink tank printer in Nairobi typically starts several times higher than KSh 5,150, so the Canon BH-4 print head returns a healthy machine for a fraction of that outlay. It also saves the ink already sitting in your tanks, which a new printer would not use. The maths only shifts if the printer also has a failing paper feed, a dead scanner, or a waste ink pad at end of life.
Will refilled or third-party ink damage the Canon BH-4 print head?
It can. Nozzles measuring a few microns across clog when pigment particles, dyes, or preservatives differ from Canon's own GI-series formulation. Cheap ink is the single most common reason Kenyan users replace heads twice in one year. Genuine Canon GI-490 or GI-590 bottles, matched to your model, protect the part you just bought. Mascom International stocks the correct Canon ink bottles alongside the Canon BH-4 print head.
What should I do before fitting the new unit?
Switch the printer off at the power button rather than the wall socket, so the carriage parks properly. Wash and dry your hands, then handle the part by its plastic body only. Never touch the gold contact pins or the nozzle plate underneath, because skin oils and static both cause failures. Keep the head in its sealed pouch until the moment of fitting. Have a paper towel ready for the small amount of test ink inside.

Technical Specifications
Nozzle Layout and Droplet Control
- 1,280 nozzles fire black ink across the page width in a single pass, keeping text edges sharp at normal reading distance
- 2-picolitre minimum droplet size lays down fine detail without visible dot patterns on plain 80gsm office paper
- Thermal inkjet firing heats ink to form each droplet, the same method Canon uses across the PIXMA G-series range
- Supports printer output up to 4800 x 1200 dpi when paired with Canon ink and the correct paper setting
- Dedicated black channel means document printing draws no colour ink, cutting the cost of every text page
Printer Compatibility Across the G-Series
- Fits Canon PIXMA G1400, G1410, G1411, and G1416 single-function ink tank printers used widely in home offices
- Fits Canon PIXMA G2400, G2410, G2411, and G2415 three-in-one models that print, scan, and copy
- Fits Canon PIXMA G3400, G3410, G3411, and G3415 wireless three-in-one models with Wi-Fi Direct
- Fits Canon PIXMA G4400, G4410, and G4411 four-in-one models that add a fax unit for office use
- Canon part number 0691C002AA, previously catalogued as CA91 on older stock labels and invoices
Print Quality and Page Output
- Pigment-based black ink resists water and smudging better than dye black, useful for invoices and delivery notes
- Working life of roughly 3,000 to 7,000 pages depending on coverage, so a heavy text user replaces less often than expected
- Restores full black density on machines showing grey or washed-out text after months of hard use
- Clears horizontal banding and missing character rows that survive repeated deep cleaning cycles
- Alignment routine after fitting corrects any small offset between the black and colour heads automatically
- Output quality holds steady from the first page after fitting, with no run-in period needed
Installation Steps and Requirements
- No tools required; the carriage lock lever releases and secures the head by hand in a few seconds
- Printer must be powered on so the carriage travels to the centre servicing position before the cover opens
- Orange protective cap and clear tape peel off immediately before seating, never earlier
- Existing ink already inside the tanks continues to feed the new head, so no ink is wasted during the swap
- Printer prompts an alignment page after fitting; run it on plain A4 for correct nozzle positioning
- Whole procedure takes about five minutes, removing the need for a service centre booking or courier trip
Ink Handling and Long-Term Care
- Pair with Canon GI-490 or GI-590 bottles matched to your printer model to keep nozzle chemistry consistent
- Third-party and refilled ink is the most frequent cause of early nozzle failure in Kenyan G-series machines
- Print a few pages weekly; idle printers let ink dry inside nozzles, which no cleaning cycle fully reverses
- Keep tanks above the lower fill line, since running dry pulls air into the head and burns nozzles
- Store the printer away from direct Nairobi sun and dust, both of which shorten head life measurably
- Run a nozzle check pattern monthly to catch partial clogging while cleaning cycles can still clear it
Handling, Storage, and Shelf Life
- Sealed foil pouch keeps the nozzle plate moist and free of dust until the moment of fitting
- Gold contact pins carry the printer's firing signals; a single fingerprint on them can stop the head registering
- Store spare units flat, indoors, and out of direct heat, matching typical Nairobi indoor room conditions
- Small amount of factory test ink sits inside the unit, so hold it level and keep a paper towel nearby
- Plastic housing and integrated tank saddles are moulded to Canon's own dimensions for a firm carriage fit
- Nairobi CBD humidity poses no risk while the pouch stays sealed, so buying a spare ahead of failure is practical
Package Contents
- One Canon BH-4 Black Print Head, part number 0691C002AA, sealed in a protective foil pouch
- Orange nozzle cap and clear protective tape fitted to the unit for transit
- Canon retail box with part identification and handling instructions
Note: ink bottles are not included, as the head draws from the tanks already fitted to your printer. Canon GI-490 and GI-590 ink bottles, plus the matching CH-4 colour head, are stocked separately at Mascom International for buyers replacing both units at once.
Warranty
