Abstract
It is known that White ink requires to be in continuous movement to avoid pigment deposition.
Sometimes, customer needs to keep the White printheads out of the carriage. As they cannot be just
stored in a shelf, a PH wheel has been created to keep the Printheads in constant movement and,
therefore, the pigment properly dispersed.
The printer needs to know that the Printheads are in the Wheel while they are not in the carriage, so a
sensor in the wheel is required to check it. As the Wheel is constantly rotating, this invention proposes
to use the change on the capping position that happens once the Printhead has been installed in the Wheel.
