Abstract
A print material cartridge (215) that includes a reservoir to maintain an amount of print material (Toner) therein; an agitator (230) formed within the reservoir to fragment clumps of print material present in the reservoir; and a tab (235) mechanically coupled to the agitator via a gear system (240), the tab extending out of a housing of the print material cartridge to activate the agitator as the print material cartridge is being interfaced with a printing device (205, 410).

A print material cartridge, comprising:
- a housing;
- a reservoir to contain a print material;
- an agitator within the reservoir to fragment clumps of the print material present in the reservoir;
- a gear system;
- and
- a tab mechanically coupled to the agitator via the gear system, the tab protruding from outside the housing of the print material cartridge to activate the agitator as the print material cartridge is being interfaced with a printing device, the tab to cause a sliding motion of the agitator inside the reservoir, the agitator comprising a shovel member to shovel an amount of the print material as the agitator slides inside the reservoir.
