Abstract
The suction and covering device (4, 4a, 4b) described has flexible rubber insert caps (41, 41a) with a fluid-absorbing lining (42, 42a), for suctioning ink from the print heads (80) and for sealing the print heads hermetically. Each rubber insert cap (41, 41a) is associated with a duct (403, 415, 463) for pressure compensation in the rubber insert cap and with an aspiration duct (401, 400) for removing ink. In order to ensure controlled removal of ink from each rubber insert cap (41, 41a), each suction duct (401, 400) has a valve device (48, 420), wherein the valve device may be a slit-type valve or a capillary filter. A controllable closure or a diaphragm in the pressure-compensation duct prevents air from being forced into the jet nozzle apertures when coupling up.
