HP OfficeJet 6812 ink cartridges

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 6812 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 6812 printers’ life. 

1. Turn on your HP OfficeJet 6812 and open the cartridge access door. Wait until the carriage stops moving before you continue. This should take only a few seconds. 
2. Hold the ink cartridge for HP OfficeJet 6812 upside down for 1-2 minutes. Then remove orange protective cap carefully. 
3. Match the label color with the color on the carriage. Then install the cartridge into the corresponding slot. 
4. 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.
