Canon Print Head BH-4

Canon Print Head BH-4

The Canon Print Head BH-4 is a genuine OEM black replacement printhead designed specifically for Canon PIXMA G-series ink tank printers. Additionally, it serves as a user-replaceable maintenance component, allowing owners to restore print quality at home rather than sending the printer to a service depot. Moreover, it is particularly relevant to ink tank printer users who experience streaking, banding, faded text, or inconsistent black output after extended use.

The BH-4 handles black ink delivery across the full width of each printed page. Consequently, it is the component most directly responsible for the sharpness and density of text documents, receipts, reports, and monochrome graphics. Canon engineered it using FINE (Full-photolithography Inkjet Nozzle Engineering) technology, which furthermore controls ink droplet placement at a microscopic level. As a result, text prints with clean edges and consistent density from the first page to the last.

Because PIXMA G-series printers use refillable ink tanks rather than disposable cartridges, the print head itself bears more long-term wear than in conventional cartridge-based systems. However, the BH-4’s user-replaceable design means that when print quality declines — despite full ink tanks and completed cleaning cycles — owners can replace the print head independently. Therefore, the printer’s working life extends considerably without the cost or inconvenience of a full unit replacement. Installation requires no tools: unlock the blue lever inside the carriage, lift out the old unit, and seat the BH-4 firmly until it clicks. The printer detects the new head automatically, after which a nozzle check confirms correct installation.

Use Cases and Applications

Restoring degraded print quality — The most common reason to replace the BH-4 is persistent streaking, banding, or faded black output that cleaning cycles fail to resolve. Additionally, if ink tanks are full but black prints appear patchy, the print head is typically the component at fault. Replacing it with a genuine BH-4 furthermore restores output to factory standard without requiring a new printer.

High-volume home and small office printing — PIXMA G-series printers are popular in environments with moderate to high monthly print volumes. However, sustained use gradually degrades nozzle performance. Consequently, the BH-4 is a cost-effective maintenance part for offices that rely on G-series printers for invoices, correspondence, and reports.

Educational and institutional settings — Schools and training centres using G-series ink tank printers for handouts, worksheets, and administrative documents benefit from the BH-4’s straightforward replacement process. Moreover, having a spare unit on hand eliminates printing interruptions during critical periods such as exams or enrolment.

Extending printer lifespan — Replacing a worn print head costs significantly less than purchasing a new printer. Therefore, the BH-4 is a practical choice for users who want to maximise the return on their existing PIXMA G-series investment. As a result, the total cost of ownership over the printer’s working life decreases meaningfully.

Spec Notes and Caveats

• Nozzle count: The 1,280-nozzle figure is sourced from a third-party Kenyan reseller (Novatech Technologies). Canon’s official product pages for the BH-4 do not publish nozzle count publicly. This figure should be verified against Canon’s technical documentation or removed if confirmation is unavailable.
• BH-4 vs CH-4: The BH-4 is the black print head only. The CH-4 is the separate colour (cyan, magenta, yellow) print head for the same printer range. Both must be functional for full colour printing. If you are listing the CH-4 separately, ensure distinct keyphrases to avoid cannibalisation.
• Ink type compatibility: The BH-4 is designed for use with Canon’s pigment black ink bottles (GI-490 BK or equivalent G-series black ink). Using third-party inks with a genuine print head may affect longevity and is generally not recommended.
• External link: The Canon Middle East store URL (en.canon-me.com) has been used as the official reference since it is the most direct Canon-published product page found for this part number. Update to a Canon Africa or Canon Kenya URL if one becomes available.
