An ink solvent application system applies an inkjet ink solvent with a wiper to clean ink residue from an inkjet printhead. The solvent is stored in a porous applicator and extracted using capillary forces generated when the wiper is rubbed across the applicator. To retain sufficient amounts of ink solvent on the wiper, the wiper moves away from the applicator in a coordinated motion having both rotational and translational components. This coordinated motion for picking solvent from the applicator is superior to a purely rotational stroke of the wiper, which picks very little solvent. The wiper then wipes the solvent across the printhead to dissolve accumulated ink residue. The wiper then moves across a blotter to remove dissolved ink residue and dirty solvent from the wiper. A method of cleaning ink residue from an inkjet printhead, along with an inkjet printing mechanism having such a solvent application system, are also provided.
