Make sure the ink cartridges are correctly installed
1. Make sure the printer is turned on.
2. Open the ink cartridge access door by lifting from the front right of the printer, until
the door locks into place.
NOTE: Wait until the print carriage stops moving before proceeding.
3. Make sure the ink cartridges are installed in the correct slots.
Match the shape of the icon and color of the ink cartridge with the slot that has the
same shaped icon and color.
4. Run your finger along the top of the ink cartridges to locate any cartridges that are
not snapped completely down.
5. Press down on any cartridges that are sticking up.
They should snap down into place.
6. If an ink cartridge was sticking up and you were able to snap it back down into place,
close the ink cartridge access door and check if the error has gone away.
•
If the error has gone away, stop troubleshooting here. The error has been
resolved.
• If the error has not gone away, proceed to the next step.

the ink cartridge did not make a snapping noise, the tab might need to be readjusted.
