Tips for working with cartridges

Use the following tips to work with cartridges:

To protect the cartridges from drying out, always turn the printer off using the On button, and wait until the On button light goes out.

Do not open or untape cartridges until you are ready to install them. Leaving tape on the cartridges reduces ink evaporation.

Insert the cartridges into the correct slots. Match the color and icon of each cartridge to the color and icon for each slot. Make sure the cartridges snap into place.

Alignment is automatic after new cartridge installation. Alignment can also help later, in cases of blurred or jagged lines. See Fix print quality issues on page 104 for more information.

When the Estimated Ink Levels screen shows one or both cartridges in a low state, consider getting replacement cartridges to avoid possible printing delays. You do not need to replace the cartridges until print quality becomes unacceptable. See Replace the cartridges on page 75 for more information.

If you remove a cartridge from the printer for any reason, try to replace it again as soon as possible. Outside of the printer, if unprotected, cartridges begin to dry out.
