Abstract
A service station system for cleaning printheads, particularly inkjet printheads is provided. The service station includes a body having a seal attached thereto and at least one pressure operated sprayer attached to the body within an area demarcated by the seal. Each sprayer includes a bent cap, which enables spraying a cleaning agent at a predetermined spray angle. The sprayers are positioned so that substantially all of the nozzle plate will be wetted by the cleaning agent when the seal, the body and the nozzle plate are positioned to form an enclosed volume. The service station also includes a pressure release valve to keep the pressure within the enclosed volume at atmospheric level during spraying.
