1.3.5 Replacing the ink cartridge
When a color BJ cartridge is used, the ink cartridge must be replaced. Use the
following procedure to replace the ink cartridge.
1) When to replace the ink cartridge
When the ink runs out or more than 6 months have elapsed since the cartridge was
removed from the package, or if the print quality does not improve even after
cleaning the head five times or more, replace the ink cartridge with a new one. Since
the three color inks are integrated, the entire color ink cartridge must be replaced
when one color ink runs out.
If the print quality does not improve following replacement of the ink cartridge and
after cleaning the head five times or more, replace the color BJ cartridge.
2) Removing an ink cartridge
Open the front cover to move the carriage to the cartridge replacement position. Flip
up the cartridge lock lever as described in 1.3.4-3), “Replacing the BJ cartridge” (page 3-
6) . Then, pull out the upper portion of the ink cartridge to be replaced to remove it
as shown in the figure below. There will be ink on and around the ink outlets of the
ink cartridge. Remove the ink cartridge carefully to avoid smears on hand and
machine.
3) Installing an ink cartridge
Take out the new ink cartridge (option) from its package and remove the cap
covering the ink outlets as shown in the figure below. Install the ink cartridge by
following the removal procedure in reverse. After installing the ink cartridge, close
the
front cover to return the carriage to the capping position.
