What Ink Does the HP OfficeJet 4620 Use?

Quick answer: The HP OfficeJet 4620 uses HP 564 ink in four separate cartridges: black, cyan, magenta and yellow. The high-yield HP 564XL Black prints about 550 pages and the 564XL colors about 750 pages each.

HP OfficeJet 4620 Ink Cartridges at a Glance

The same HP 564 / 564XL cartridges fit the OfficeJet 4610 and 4620 series, the DeskJet 3520 and 3510 series, and the Photosmart 5510 and 5520-era HP 564 printers such as the Photosmart 6520 and 7520. The OfficeJet 4620 uses four colors only; it has no photo black slot.

The OfficeJet 4620 is a wireless all-in-one with print, scan, copy and fax plus a document feeder. Its separate ink tanks mean you only replace the color that runs out.

Do not confuse HP 564 with HP 920 or HP 950/951. They are used in other OfficeJet models and will not fit the 4620.

How to Replace the Ink in the HP OfficeJet 4620

1. Turn the printer on and open the ink cartridge access door. Wait for the carriage to stop.
2. Press the tab on the front of the cartridge you are replacing and lift it out of its slot. Each color sits in its own labeled slot.
3. Unwrap the new cartridge and twist off the orange cap. Do not touch the copper contacts.
4. Push the cartridge into its matching color slot until the tab clicks.
5. Close the door and let the printer finish initializing before you print.

Troubleshooting Tips

"Cartridge problem" or "incompatible cartridge": Take the cartridge out, check that the orange cap is off, wipe the copper contacts with a dry lint-free cloth and push it back in until it clicks. Our HP cartridge not recognized guide covers every other HP message.

"Printhead problem" or faded color: HP 564 printers use a separate printhead that the cartridges plug into. Run "Clean Printhead" from the Tools menu, and if a color stays faded after two cleanings, power the printer off, wait a minute and try again.

Replacing one color at a time: Each color is a separate cartridge, so you only replace the one that runs out. The printer will not print until every slot has a cartridge in it.
