indicated by the arrow shown here, until it clicks into place.
If you have difficulty, see I cannot insert a printhead cleaner on page 168.
NOTE: The front panel will not show the new printhead cleaner until the right-hand door is closed.
3. When you have inserted the printhead cleaner(s) into the printer, close the door.
NOTE: The printer needs all the ink cartridges, printheads and printhead cleaners to be installed
before it can continue.
4. If no paper is loaded, the front panel will instruct you to load some.
Whenever you insert a new printhead and cleaner, the printer will normally perform a printhead alignment
and color calibration. Both are recommended for best print quality. In some cases, you may decide to
postpone printhead alignment until after some further printing has been done.
