NOTE: At this time, some portions of the HP Web site are available in English
only.
NOTE: Not all cartridges are available in all countries/regions.
CAUTION: Wait until you have a new ink cartridge available before removing the
old ink cartridge. Do not leave the ink cartridge outside of the printer for an
extended period of time. This can result in damage to both the printer and the ink
cartridge.
Use these steps to replace the ink cartridges.
To replace the ink cartridges
1. Make sure the printer is turned on.
2. Open the ink cartridge access door.
WARNING! Wait until the print carriage stops moving before proceeding.
3. Press the tab on the front of the ink cartridge to release it, and then remove it from
the slot.
4. Remove the new ink cartridge from its packaging by pulling the orange pull-tab
straight back to remove the plastic wrap from the ink cartridge.
NOTE: Make sure you remove the orange pull-tab completely and the label is
slightly torn before you remove the orange cap in the next step, or ink can leak.
