Important Ink Information

After the printheads are installed and primed with ink, do not open the printhead latch unless you are installing 

new printheads or moving the printer outside your home or office.  In addition, you should maintain proper ink 

levels in the ink tanks when printing. 

Maintain proper ink levels

Use the ink level lines on the ink tanks to determine when to fill the tanks and how much ink should be added. 

Never print when any of the ink tanks has less than the minimum amount of ink. Printing with too little ink or filling 

tanks with too much ink can damage the printer and affect print quality. Make sure you match the color of the ink to 

the color on the ink tank when you refill an ink tank. See the Start here booklet for instructions on how to fill the ink 

tanks.

  

 

Minimum ink level 

Ink level should never go below the minimum ink line. 

Printing with ink level below the minimum line may cause 

damage to your printer.

  

 

Maximum ink level 

Do not fill ink above the maximum ink line. Overfilling 

might cause ink leakage. When you refill, some ink might 

be left in the ink bottle. You can save the remaining ink by 

storing the ink bottle in a dry cool place for future refilling.

NOTE

: Product service or repairs required as a result of filling the ink tanks improperly and/or using non-HP ink will 

not be covered under warranty.

 Moving printer after setup

To prevent damage to the printer or ink leakage, follow these instructions.

If you are moving the printer within your home or office, keep the printhead latch closed, and keep the printer level.
If you are moving the printer outside your home or office, follow the instructions in the relevant section of the Start 

here booklet provided in the printer box or the user guide available at 

www.support.hp.com
