Abstract
A hardcopy device such as an ink-jet printer comprises a printhead, a spittoon for receiving waste ink from the printheads, and a heater for quickly drying the ink waste products in the spittoon. A drum platen having a print media supporting area also has an elongate spittoon region extending across its circumferential surface, the contents of the spittoon region being arranged to be removed intermittently by an elongate scraper which, in one position of the drum, can be moved radially towards the drum to contact the spittoon region.
