An indexing wiper scraper cleaning system for cleaning a scraper, which has removed ink residue from a wiper following an inkjet printhead wiping routine where the residue was first removed from the printhead in an inkjet printing mechanism, has a reservoir filled with an ink solvent. Rotary scraper member having a series of scraper bars projecting radially from a cylindrical body is supported to periodically soak at least one of the scraper bars in the ink solvent bath. Following this soaking, the scraper bars are rotated through an indexing motion into a scraping position to scrape the ink residue from the wiper where the wiper is scraped across a positioned one of the scraper batrs, thereby leaving he remaining scraper bars untouched. After the scraping operation, the scraper bars are returned to the solvent bath to ready them for the next scraping operation. A method of cleaning an inkjet printhead, along with an inkjet printing mechanism having such a indexing wiper scraper cleaning system are also provided.
