Abstract
A cartridge for a printing system comprises a receptacle to receive waste printing material from the printing system, a floater to change its position based on a varying filling level of the waste printing material in the receptacle, and a flag mechanically coupled to the floater, wherein a position of the flag depends on the position of the floater and indicates, outside of the receptacle, the filling level.
Claims20
A cartridge for a printing system, comprising:
- a receptacle to receive waste printing material;
- a floater to change its position based on a varying filling level of the waste printing material in the receptacle;
- a flag mechanically coupled to the floater, wherein a position of the flag depends on the position of the floater and indicates, outside the receptacle, the filling level;
- wherein the flag extends outside a housing of the cartridge and extends further from the cartridge as the floater rises to indicate more waste printing material in the receptacle.

A printhead cleaning system for a printing system, comprising:
- a printing arrangement to receive a replaceable printhead cleaning cartridge and move the cartridge forward and back;
- the printhead cleaning cartridge having:
- a waste volume to collect waste printing material, a floater to change its position based on an amount of the waste printing material in the waste volume, and a flag mechanically coupled to the floater, wherein a position of the flag depends on the position of the floater and indicates, outside the cartridge, the amount of waste printing material;
- a sensor element to detect the flag when extending outside the cartridge;
- and
- a mechanical actuator coupled to the floater, wherein movement of the cartridge actuates the mechanical actuator to lift the floater away from contact with waste printing material collected in the waste volume.
