How to install compatible ink cartridges in the HP OfficeJet Pro 6978
What you need to know before the installation:
- Do not touch the chip or the ink port, which can result in clogs, ink failure and poor electrical connections.
- Avoid mixing cartridges from different suppliers simultaneously – the printer may not recognize them properly.
- If the HP OfficeJet Pro 6978 has not been used for a long period of time, we recommend running the printhead cleaning cycle up to 3 times to remove ink residue (refer to the printer manual).
- The Smart Ink team strongly recommends using only high-quality ink from one producer to extend HP OfficeJet Pro 6978 printers’ life.
- Turn on your HP OfficeJet Pro 6978 and open the cartridge access door. Wait until the carriage stops moving before you continue. This should take only a few seconds.
- Hold the ink cartridge for HP OfficeJet Pro 6978 upside down for 1-2 minutes. Then remove orange protective cap carefully.
- Match the label color with the color on the carriage. Then install the cartridge into the corresponding slot.
- If the ink cartridge does not seat properly, remove it from the carriage. Gently bend the tab away from the cartridge, and reinsert it into the carriage.
NOTE: There are several sizes of the black cartridge that can be used in the cartridge slot for black, Smart Ink 902L/903L should be installed in the middle of the black cartridge slot.
