HP GT Printheads M0H50A / M0H51A
Replacement printheads for HP's Ink Tank / GT series — the M0H50A tri-color and M0H51A black heads that bring a streaking or blank-printing tank printer back to life without replacing the machine.
Which printers this fits
HP GT series and Ink Tank printers that use the GT printhead system. The two heads (black and tri-color) replace independently — identify which side is failing from a nozzle-check print, or send us the test page and we'll tell you.

The repair that saves the printer
Ink Tank printers are economical precisely because ink is cheap — but the printheads are working parts that eventually clog or wear beyond cleaning cycles. When deep cleans stop helping and a colour drops out entirely, a new head restores factory print quality for a fraction of a replacement printer.
Know which head before you buy
Print a nozzle check: missing black means the M0H51A, missing colours means the M0H50A. WhatsApp us the test page photo if unsure — we'd rather diagnose for free than sell you the wrong head.
