Canon i860 i865 MP750 MP760 MP770 MP780 MP790

The Graviton QY6-0049 printhead is a new replacement part for the listed Canon inkjet printers. It restores colour printing function when the original head wears out or clogs beyond cleaning. The part is built in ISO9001:2000 certified factories using automated precision equipment. It arrives in a neutral package weighing 70g.

Thermal and Power Characteristics

The printhead operates on both 110V and 220V supplies, matching the printer's internal power design. Normal inkjet printing generates minimal heat and the head runs quietly during everyday document output. Power draw is limited to the printer's standard operating envelope. No additional cooling or voltage regulation is required.

Build Integration

The unit measures 9x4x8.5cm and fits directly into the print carriage of each compatible model. Installation frees the printer from streaks, missing colours or head-alignment errors caused by a worn head. It requires no firmware update, extra cabling or chassis modification. Buyers needing a different Canon part number or a complete printer will not be served by this item.

Questions about this item

How do I install the QY6-0049 printhead in my Canon MP760 and which step is often missed?

Open the printer cover, wait for the carriage to centre, lift the locking lever, remove the old head, insert the new QY6-0049 until it clicks, lower the lever, close the cover and run the head-alignment routine — skipping the alignment is the step most people miss.

What maintenance or replacement will the QY6-0049 printhead need over time?

The printhead itself is a consumable; expect to replace it when nozzles clog permanently or print quality drops after repeated deep-cleaning cycles. Periodic nozzle checks and gentle cleaning with distilled water extend its life.

What limit appears first on the QY6-0049 during long print runs?

The 110 V / 220 V thermal protection circuit will shut the head down if it overheats during sustained high-coverage printing, pausing output until the assembly cools to a safe temperature.
