Frequently Asked Questions

I remove and reinstall the same ink cartridge—do I have to align the print cartridges again on my HP Officejet J3640?

No. The HP Officejet J3640 remembers the alignment values for that reinstalled ink cartridge, so you don't have to realign the cartridges.

Where do I position the black and the tri-color ink cartridges inside the Officejet J3640?

The black and the tri-color ink cartridges have designated slots inside the Officejet J3640. So, when installing them, make sure to insert the tri-color ink cartridge into the left slot and the black ink cartridge into the right slot.

What will happen if I accidentally touched the copper-colored contacts or ink nozzles on the new cartridge?

Touching the nozzles or copper-colored contacts can lead to bad electrical connections, ink failure, and clogs, so take extra caution when handling the new ink cartridge.
