How to install compatible ink cartridges in the HP OfficeJet Pro 8640
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 printer 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 printer life.
- Turn on the printer and open the cartridge access door. wait until the carriage stops moving before you continue. This should take only a few seconds.
- Take off the yellow tape.
- Do not remove the protective seal covering the ink port.
- Match the label color with the color on the carriage. Then install the cartridge into the corresponding slot.
