Abstract
A printer has a press frame and a roll rotatable in the frame about an axis and having a radially outwardly directed roll surface. An ink cartridge has a housing having a pair of support plates juxtaposed with and angularly spaced along the roll surface. Doctor blades supported on the support plates have outer edges resiliently engageable with the surface. One of the doctor blades is shiftable on the housing between an open position and a closed position with the outer edges engaging each other. Interengageable formations on the housing and on the press frame are movable between a use position retaining the housing on the press frame with the outer edges engaging the surface and a removal position. An actuating element is shiftable to move the one doctor blade from the open position to the closed position and shift the formations from the use position into the removal position.
