Abstract
A replaceable inkjet printhead service module is provided for each separate inkjet printhead. When the printhead for a particular color ink such as cyan has reached the end of its life cycle and requires replacement, the corresponding printhead service module can also be replaced. The printhead service module includes a handle to facilitate manual mounting in a service station carriage which includes identical individual spring-loaded slots with datum guides for securely holding the service module. The service station carriage moves from a user-accessible position for mounting/removing the service module, to various other printhead servicing positions in the path of the printhead carriage.
