Tubeless printhead-priming cap and system for ink-jet printers are described. The system is preferably implemented, using the existing printer carriage drive motor, by the use of a printhead-sealing cap having a rolling diaphragm in a lower region thereof that defines a chamber within the priming cap, with the diaphragm being reciprocated, by a spring-returned lever having a piston on one end thereof, in synchronism with lateral and differential vertical movement of a cap-carrying sled. Priming is performed uni-directionally to avoid reverse priming of the printhead. The chamber may be emptied by reversing the operation of the priming cap to pump accumulated ink into a blotter by positioning the priming cap against an ink blotter provided in a rotatable member defining a multi-service station.
