ABSTRACT:
An ink jet printer has a recovery system for sucking ink from nozzle orifices together with air bubbles stagnant in orifices so as to recover the normal state in the orifices. The recovery system has a vacuum generating device, a capping device and a valve mechanism for controlling the vacuum generated in the vacuum generating device to the capping device. The recovery system further has a temperature detector for detecting the temperature of the ink. The operation timing of the valve mechanism is controlled in accordance with the temperature of the ink detected by the temperature detecting means, so that the amount of ink sucked by the recovery system is regulated in accordance with the temperature of the ink.
