HP OfficeJet 6962 Printhead Replacement
Collect the items: Distilled water, Isopropyl alcohol, dry wipes, lint-free cloth, white towels, and bowls. Keep your 123.hp.com/oj6962 printer, computer, and the cleaning-kit on a flat surface.
Power on your HP printer and unlock the ink cartridge access panel. Wait until the carriage moves from left to right. Take both black and tricolor ink cartridges out of their slots. Locate the printhead assembly.
Elevate the gray-colored lever upwards and the printhead moves from its position. Hold the printhead on both sides and take it out without touching the electrical wiring. Spread a white towel and place the printhead on it.
Take a bowl and create a cleaning mixture that contains 50% distilled water and 50% Isopropyl alcohol in it.
Stir the mixture until the abrasive effect of the alcohol reduces. Take the printhead with the color-codes facing up and place it in the mixture until it completely dissolves.
Some HP printer models use cartridges with an inbuilt printhead. In that case, place the cartridge in the mixture. Keep the setup aside and do not disturb it for five minutes.
The mixture removes the dried ink on the printhead. After five minutes, take the printhead out, wrap it in a lint-free cloth, and let it dry for a few minutes.
Unwrap the printhead and remove the excess moisture using the dry wipes. Reinsert the printhead into the assembly and the cartridges into the designated slots. Close the cartridge access panel.
