Condition: New
Note: price and availability are subject to change without prior notice
Canon BH-40 Black Print Head is available at Mascom International for KSh 5,150, built for the PIXMA G2420, G2430, G3420 and G3430 ink tank printers. Every unit we sell is brand new and sealed in Canon's original pack. It is a genuine Canon replacement print head that handles all the black ink these machines put on paper, from body text to table borders. Pick one up at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD, or have the Canon BH-40 Black Print Head brought to your door on pay-on-arrival terms. Staff check your model before the sale.
Designed for accountants, lawyers, school administrators and cyber café operators, the Canon BH-40 Black Print Head handles the pages that keep a business running. When this head wears out, letters print with white lines through them, invoices come out grey, and some characters vanish halfway down the sheet. Colour may still look fine, which makes the fault confusing. Owners often buy new ink first and see no change. Swapping in a Canon BH-40 Black Print Head fixes the real problem and saves you from replacing a printer whose scanner, tanks and paper feed still work.
Unlike other electronics retailers in Kenya that stock loose heads of unknown origin, Mascom International sells this part sealed, with its protective cap and tape intact. At Mascom International, we're seeing more G2420 and G3420 owners repair rather than replace, especially offices in Upper Hill and Industrial Area that print daily. Buyers throughout Kenya report that sharp black text is what clients and examiners notice first. Order the Canon BH-40 Black Print Head on WhatsApp with your model number, settle by Lipa na M-Pesa on arrival, or walk into our Kimathi Street shop and let us confirm the fit.
Common Questions About the Canon BH-40 Black Print Head
What is the Canon BH-40 Black Print Head price in Kenya?
The Canon BH-40 Black Print Head sells for KSh 5,150 at Mascom International in Nairobi CBD, brand new in a sealed Canon pack. For that amount you get the black head with its protective cap and tape, a 6-month defect warranty, and pay-on-arrival delivery to any county. The matching Canon CH-40 Colour Print Head carries the same KSh 5,150 price, so replacing both heads together comes to KSh 10,300.
Which PIXMA printers take the Canon BH-40 Black Print Head?
The Canon BH-40 Black Print Head is listed for the PIXMA G2420, G2430, G3420 and G3430. These are Canon's second-generation ink tank models, so the head will not fit the older G2010, G3010 or G4010. The model name is printed on the front of the printer near the control panel. Send us a clear photo of it on WhatsApp before ordering, and our team at Mascom International will confirm the part matches your machine.
What problems show that the Canon BH-40 Black Print Head has failed?
Faint, broken or streaky black text that survives refills and cleanings is the clearest sign of a worn Canon BH-40 Black Print Head. Look at the nozzle check page: if the black block shows missing lines or blank patches while colour looks complete, the black head is the suspect. Other clues include grey instead of solid black, stray marks on blank areas, and a printer that keeps flashing an alarm after you fit fresh ink.
Should I run a deep cleaning before buying a Canon BH-40 Black Print Head?
Yes, run a cleaning cycle first, since a dried black nozzle often recovers without a new head. Confirm the black tank sits above its lower mark, print a nozzle check, then do one cleaning and one deep cleaning, checking after each. Leave the printer off overnight and try again in the morning. Ink sitting idle over a long holiday is a common culprit. If black lines are still missing, the Canon BH-40 Black Print Head needs replacing.
Do I need to replace the Canon CH-40 Colour Print Head at the same time?
You only need to replace the head that is failing, because the Canon BH-40 Black Print Head and the Canon CH-40 Colour Print Head work as separate parts in the same printer. If only black output is weak, the BH-40 alone fixes it. Change both when the nozzle check shows gaps in black and colour, or when the printer is several years old and prints heavily. Both sell at KSh 5,150 each at Mascom International.
Can I fit the Canon BH-40 Black Print Head myself?
Most owners fit the Canon BH-40 Black Print Head themselves in under ten minutes, with no tools. Open the scanner unit while the printer is on, release the locking cover above the head holder, and lift out the old black head from its holder. Remove the cap and tape from the new head, slot it in, and push the cover shut until it clicks. If you would rather not, bring the printer to our Kimathi Street shop and our staff can help.
How does Kenyan dust and humidity affect the Canon BH-40 Black Print Head?
Dust and humid air are real risks for the Canon BH-40 Black Print Head, so store and install it with care in Kenya. Keep the sealed pack indoors, away from direct sun, until the day you fit it. Open the printer cover only when needed, especially in dusty spots near roads in Industrial Area or on the way to Machakos. In humid Mombasa and Kisumu, close the paper tray and keep the printer covered between jobs.
Who should buy the Canon BH-40 Black Print Head, and who should skip it?
The Canon BH-40 Black Print Head is right for owners of a G2420, G2430, G3420 or G3430 whose colour prints well but black text has gone patchy. Law firms, accounts offices and university students printing assignments at Kenyatta or JKUAT benefit most. Skip it if colour is also failing, since the CH-40 may be needed too. Anyone with an older G2010 or G3010 needs the CH-4 range, not this head.
Technical Specifications
Core Function
- Dedicated black print head — it lays down all black text, lines and dark areas on every page you print.
- Separate from the colour head — when only black fails, you replace this single part and keep the rest of the system.
- Fed by the printer's black ink tank through a tube — you refill from bottles instead of buying new cartridges.
- Fixes broken, faint or grey black output — invoices, contracts and exam papers return to solid, readable text.
- Genuine Canon replacement part — the head type these printers were designed around, so text quality matches the original.
- Handles the bulk of office printing — most daily pages are black text, so this head usually does the most work.
Compatibility
- PIXMA G2420 — print, scan and copy ink tank model found in many Kenyan homes and small offices.
- PIXMA G2430 — a close sibling of the G2420, taking the same black head.
- PIXMA G3420 — wireless all-in-one model, so you can print from a phone over Wi-Fi once the head is fitted.
- PIXMA G3430 — wireless all-in-one that also uses this exact black head.
- Not for the G1000, G2010, G3010 or G4010 — those earlier models use a different print head system.
- Works alongside the Canon CH-40 Colour Print Head — the two heads sit side by side in the same holder.
Build
- Nozzle face underneath — touching it can leave oil that blocks the fine holes, so handle the head by its sides.
- Gold contact strip — this is how the printer talks to the head, so keep it clean and dry.
- Protective cap and tape — they stop the nozzles drying out and keep dust off until installation.
- Click-in fit under the locking cover — a secure seat prevents misprints and error alarms.
- Light plastic housing — sturdy enough for normal handling, though it should not be dropped.
Inclusions
- One Canon BH-40 Black Print Head in sealed packaging — keep it closed until you are ready to install.
- Factory protective cap and tape on the nozzles — peel these off only right before fitting.
- No black ink bottle — top up your tank from a separate bottle if it is running low.
- No colour head — the Canon CH-40 Colour Print Head is sold separately at the same price.
- No tools or setup disc — the printer recognises the head without extra software.
Care and Running Cost
- Print a black test page every few days — idle ink is the main reason black nozzles block.
- Keep the black tank topped up — letting it run dry sends air into the head and causes white lines.
- Turn the printer off with its own button — the head then parks under its cap and stays sealed.
- Use a surge protector during KPLC outages — sudden cuts and spikes can stress the head's electronics.
- Check nozzles before long print runs — catching a gap early saves paper and ink.
Package Contents
Inside the box is one Canon BH-40 Black Print Head, sealed, with its protective cap and tape fitted. Nothing else is included, so plan for ink bottles or the colour head separately if your printer needs them. Leave the seal unbroken until you are at the printer and ready to install. Our team at Mascom International can tell you on WhatsApp which matching items are in stock.
Warranty
The Canon BH-40 Black Print Head carries a 6-month warranty from Mascom International against manufacturing defects under normal use. Should the head arrive faulty or fail due to a defect, return it with proof of purchase to our Nairobi CBD service desk at Old Mutual Building on Kimathi Street.
