The invention provides for a dispensing assembly (100, 100', 100", 200, 300, 500, 600, 700, 900) comprising a cartridge holder (102). The cartridge holder is operable for receiving a cartridge (108, 108', 108") operable for dispensing a fluid (206). The cartridge comprises a reservoir (114, 804, 908) operable for receiving the fluid. The reservoir comprises an outlet (115, 806). The reservoir has an adjustable volume for forcing the fluid through the outlet. The cartridge further comprises a nozzle (116, 912) for dispensing the fluid. The nozzle is connected to the outlet. The dispensing assembly further comprises an actuator (104) for actuating the adjustable volume. The dispensing assembly further comprises an impulse generator (106) for imparting an impulse to the nozzle. The impulse generator comprises an actor (118) for contacting the nozzle. The dispenser assembly further comprises a controller (202, 420) for controlling the actor and the impulse generator.
