Abstract:
An inkjet recording apparatus includes a droplet ejection head, a head tank, a tube, an ink cartridge, and a liquid-feed pump. The droplet ejection head has a plurality of nozzles for ejecting ink. The head tank is mounted on the droplet ejection head, temporarily stores a certain amount of ink, and creates negative pressure in the droplet ejection head. The tube is connected to the head tank. The ink cartridge is connected via the tube to the head tank, the ink cartridge storing ink. The liquid-feed pump is disposed at the tube between the ink cartridge and the head tank to feed ink from the ink cartridge to the head tank through the tube. The liquid-feed pump is operable in reverse to feed ink from the head tank through the tube to the ink cartridge and create negative pressure in the head tank.
