Canon BH-40 Black Print Head – Genuine Replacement Printhead for PIXMA G2420, G2430, G3420 and G3430

The Canon BH-40 Black Print Head is a genuine Canon replacement component designed for selected Canon PIXMA G-Series MegaTank printers. It delivers black ink onto paper through a precision-engineered nozzle system, producing sharp text, clear documents and consistent monochrome printing.

If your Canon printer produces faded black text, missing lines, streaks or inconsistent black output due to a damaged or permanently clogged printhead, replacing the printhead may help restore normal printing performance.

Designed for Canon PIXMA G2420, G2430, G3420 and G3430 printers, the BH-40 is a suitable replacement component for home users, offices, businesses and printer maintenance professionals.

What Is the Canon BH-40 Black Print Head?

The Canon BH-40 is an original black inkjet printhead developed for compatible Canon PIXMA MegaTank printers. Unlike an ink bottle, which stores and supplies ink, the printhead controls how ink is deposited onto paper through microscopic nozzles.

The BH-40 handles the black ink channel, helping produce clearly defined text, fine details and professional-looking monochrome documents.

It works alongside the Canon CH-40 Colour Print Head, which handles cyan, magenta and yellow ink. Together, these components support black and colour printing in compatible Canon printers.

The BH-40 is particularly useful when the original black printhead becomes damaged, worn or permanently clogged and cannot be restored through normal printer maintenance.
