An example image forming apparatus includes a main body, a driving motor, a developing cartridge, and a clutch. The developing cartridge includes a toner container, a mounting portion to receive a toner refill cartridge, a toner inlet portion to connect the mounting portion to the toner container, and a toner inlet shutter to be switched between a blocking location for blocking the toner inlet portion and an inlet location for opening the toner inlet portion. The clutch is to selectively transmit a driving force of the driving motor to the toner inlet shutter.

A system for servicing a printhead having a plurality of orifices formed in a face thereof includes a cap configured to mate with the face of the printhead; a porous material provided in the cap, wherein the porous material has a first side arranged to face the face of the printhead and a second side opposite the first side; and a vacuum communicated with the cap, wherein the vacuum is configured to draw fluid from the orifices of the printhead through the porous material provided in the cap. The second side of the porous material has a recess formed therein such that the vacuum is communicated with the recess.

Printhead servicing system and method

An embodiment of the invention provides a mechanism for controlling at least one ink transmission module, which controls a supply of ink using received control rotation. The mechanism includes an input, to receive control rotation. The mechanism also includes an output, to selectively transfer the control rotation to the ink transmission module. A control system is also provided to control the selective transfer of the output. The mechanism is moveable into a disengaged configuration by the control system, in which the output does not transfer rotation of the input to the ink transmission module, by a first predetermined sequence of rotations of the input, and into an engaged configuration, in which the output transfers rotation of the input to the ink transmission module, by a second predetermined sequence of rotations of the input.
