Abstract
An example apparatus includes a cap to seal a printhead in a printhead assembly, where the cap includes a priming port and a venting port. A vent connected to the venting port is sealed by a cam controlled vent-arm while a vacuum pump connected to the priming port applies a vacuum to prime the printhead. The vent is unsealed by the cam controlled vent-arm and the vacuum pump clears ink from the priming cap.
