Canon CH-4 Colour Print Head is now in stock at Mascom International for KSh 5,150, available today at our Nairobi CBD store. This is the tri-colour unit that carries the cyan, magenta, and yellow nozzles for Canon PIXMA G-series ink tank printers, catalogued by Canon under part number 0694C002AA. The Canon CH-4 Colour Print Head fits the G1400, G1410, G1411, G1416, G2400, G2410, G2411, G2415, G3400, G3410, G3411, G3415, G4400, G4410, and G4411. Collect it from Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD, or order for pay-on-arrival delivery to any county.
Cyber cafe operators along Tom Mboya Street, school bursars running exam papers in Kiambu and Machakos, church offices producing Sunday bulletins, and SMEs issuing branded quotations all hit the same wall. Colours go flat, one shade drops out completely, and horizontal banding cuts across every image while the tanks still read full. That is a blocked or worn colour head, not an ink shortage, and no amount of refilling fixes it. Swapping in the Canon CH-4 Colour Print Head restores full-spectrum output on a machine that is otherwise sound, for a fraction of what a replacement printer costs.
Unlike other electronics retailers in Kenya, Mascom International stocks the Canon CH-4 Colour Print Head as a genuine Canon component rather than an unbranded copy, and we confirm your exact printer model before you pay a shilling. Users consistently report that genuine units hold colour accuracy across thousands of pages, while cheap copies fade or fail within weeks. At Mascom International, we're seeing repair technicians across Nairobi buy the CH-4 together with the matching BH-4 black head during full service jobs. Walk into our Kimathi Street counter with your printer details for an on-the-spot fitment check.
Common Questions About the Canon CH-4 Colour Print Head
What does the Canon CH-4 Colour Print Head control inside a PIXMA G-series printer?
The CH-4 holds every colour nozzle in the machine. Ink travels from the cyan, magenta, and yellow tanks through this single unit, which fires microscopic droplets onto the page. Black text runs through a separate BH-4 head, so the two work independently. When the CH-4 wears out or blocks, colour printing degrades while black stays sharp. That split is the clearest sign of which of the two parts actually needs replacing on your printer.
My blacks look fine but colours print wrong. Is the CH-4 the problem?
Almost certainly yes. If black text is crisp while photos come out pink, green, or washed out, the fault sits in the colour head rather than the black one. Run a nozzle check pattern from the printer menu first. Missing or broken lines in the cyan, magenta, or yellow blocks confirm it. Deep cleaning cycles may recover a lightly blocked unit, but repeated failures across two or three cleanings point to replacement.
Do I need to replace the CH-4 and the black head at the same time?
No. The two heads are separate parts with separate lifespans, and either can be changed alone. Many customers replace only the failing one. That said, technicians servicing a printer that has run four or five years often fit both, since the second unit usually fails within months of the first. Mascom International stocks the BH-4 black head at KSh 5,150 as well, so pairing them is straightforward if your test page shows problems in both.
Will the Canon CH-4 work on a PIXMA G2411 bought in Kenya?
Yes. The G2411 and G3411 are the two most common ink tank printers in Kenyan offices and cyber cafes, and both take the CH-4 without any regional restriction. The part carries no country lock, no firmware pairing, and no serial matching. Bring the printer model number to our Kimathi Street counter or send it on WhatsApp, and our team verifies the match against Canon's compatibility list before you commit to the purchase.
How do I run a nozzle check after fitting the CH-4?
Load plain A4, then open the printer maintenance menu on the control panel or the Canon utility on your computer. Select the nozzle check pattern and print it. A correct pattern shows four solid blocks with no gaps or streaks. If colour blocks still look broken, run one deep cleaning cycle and print again. Two clean patterns in a row mean the fitting worked. Our support line walks you through it if the panel menus are unfamiliar.
Why do colour heads block faster in dusty Kenyan offices?
Two reasons. Fine dust from open windows on Moi Avenue or an unpaved compound settles on the nozzle plate and mixes with drying ink. Second, machines left idle over long weekends or school holidays let ink dry inside the narrow colour channels, which are finer than the black ones. Printing a few colour pages weekly keeps ink moving. Keeping the printer lid closed and covering the unit overnight cuts dust intake sharply.
Can I clean a blocked CH-4 instead of replacing it?
Try the printer's own cleaning cycles first, since they cost nothing but ink. Run one deep cleaning, wait six hours, then test again. If three cycles fail to clear the pattern, the blockage has hardened or the nozzles are physically worn. At that point cleaning solutions and manual soaking usually cause more damage than they repair. Replacement becomes the cheaper route, and a fresh CH-4 restores output immediately without further downtime.
How does Mascom International confirm this is a genuine Canon part?
Every CH-4 we stock arrives in sealed Canon retail packaging carrying the 0694C002AA part number and Canon barcode. You can inspect that packaging at our Kimathi Street counter before paying, or check it at your door under pay-on-arrival delivery. Unbranded copies sold loose in plastic bags carry no part number and no Canon marking. Where most Nairobi shops sell heads without documentation, Mascom International hands over the boxed unit and the receipt covering it.
What does a KSh 5,150 CH-4 save a busy cyber cafe over a year?
A working colour head keeps a shop printing certificates, passport photos, and flyers instead of turning that work away. A replacement PIXMA G3411 runs roughly KSh 30,000 to KSh 38,000 in Kenya, so the head costs under a sixth of a new machine. Spread across a cafe printing 200 colour pages weekly, the outlay works out at a few shillings per page. Downtime avoided usually matters more than the part cost itself.
Technical Specifications
Colour Channel Structure and Ink Delivery
- Three ink channels carry cyan, magenta, and yellow separately, so one weak colour does not contaminate the others.
- Thermal inkjet firing heats ink to eject droplets, the same method Canon uses across the PIXMA G-series line.
- Dye-based inks pass through this head, producing smooth gradients on photo paper and clean fills on charts.
- Multi-nozzle array places droplets accurately, which is what removes the banding seen on a failing unit.
- Colour channels are narrower than black ones, so they block sooner when a printer sits unused for weeks.
- Black printing runs entirely through the separate BH-4 head and continues normally if the CH-4 fails.
Supported PIXMA Models and Regional Variants
- Fits PIXMA G1400, G1410, G1411, and G1416 single-function ink tank printers used widely in home setups.
- Fits PIXMA G2400, G2410, G2411, and G2415 all-in-one units common in Kenyan cyber cafes and clinics.
- Fits PIXMA G3400, G3410, G3411, and G3415 wireless all-in-ones, the volume seller across Nairobi offices.
- Fits PIXMA G4400, G4410, and G4411 models that add fax and automatic document feeder hardware.
- Part number 0694C002AA is the identifier printed on the box; match it before buying to avoid wrong fitment.
- Does not fit newer G1420, G2420, G3420, or G5040 machines, which take the CH-40 series instead.
Fitting Procedure and Alignment Routine
- Power the printer on, open the top cover, and wait for the carriage to move to the centre position.
- Release the blue locking lever, lift the old colour head straight out, and set it aside for disposal.
- Remove the orange protective cap from the new unit and avoid touching the gold contacts or nozzle plate.
- Seat the new head firmly, close the lever until it clicks, then shut the cover to start priming.
- Allow the printer three to five minutes to charge ink through the fresh channels before the first test page.
- Run a nozzle check and one alignment routine; the whole job takes about ten minutes without tools.
Photo, Graphic, and Document Output
- Restores full colour gamut on brochures, certificates, and school report cards printed on plain or glossy stock.
- Removes horizontal banding and streaking that appear once nozzles clog or wear past their service point.
- Handles passport and ID photo work on 4x6 photo paper, a steady earner for Nairobi cyber cafes.
- Supports borderless printing on supported paper sizes when paired with correct printer driver settings.
- Colour accuracy holds across long runs, so page 200 of a flyer batch matches page one closely.
- Works with genuine Canon GI-490 and GI-590 ink series depending on which G-series model you own.
Clog Prevention in Kenyan Working Conditions
- Print at least a few colour pages weekly; idle machines let ink dry inside the fine colour channels.
- Keep the printer lid closed between jobs to reduce dust settling on the nozzle plate.
- Store the machine away from open windows facing dusty streets or unpaved compounds during dry seasons.
- Use genuine Canon ink; poorly filtered third-party ink leaves residue that shortens head life considerably.
- Avoid switching the printer off at the wall socket, since that skips the automatic nozzle capping routine.
- Run one deep cleaning after any long idle period rather than several back-to-back cycles that waste ink.
Genuine Sourcing and Packaging Protection
- Supplied in sealed Canon retail packaging printed with the 0694C002AA part number and manufacturer barcode.
- Orange protective cap seals the nozzle plate during storage; leave it fitted until the moment of installation.
- Sealed foil pouch keeps the nozzles from drying, which is why an unopened unit stores for months.
- Handle only by the plastic body edges; skin oils on the gold contacts cause recognition errors.
- Genuine units carry Canon's own nozzle calibration, which unbranded copies rarely reproduce accurately.
- Mascom International sources through legitimate supply channels and issues a receipt with every unit sold.
Package Contents
Each Canon CH-4 Colour Print Head purchase from Mascom International includes the sealed retail box, the colour print head unit inside its protective foil pouch, the orange nozzle cap fitted to the unit, and Canon's printed installation leaflet. Your Mascom International purchase receipt is issued at the counter or handed over at delivery. No ink bottles are included, since the CH-4 draws from the tanks already fitted to your printer. Ink bottles are sold separately at our Kimathi Street store.
Warranty
The Canon CH-4 Colour Print Head carries a 6-month Mascom International warranty covering manufacturing defects under normal use. Coverage applies to units that fail to prime, fail nozzle recognition, or show factory faults from the sealed box. Blockages caused by third-party or refilled ink fall outside this cover. Our Nairobi CBD service desk handles every claim directly, with no third-party referrals.
