ABSTRACT:
An ink-jet printing apparatus includes a recovery section having a pump for discharging ink from an ink-ejection portion of a printing head by the application of a suction force thereto. In the recovery section, the pump and the waste ink absorber for retaining the waste ink are disposed approximately at the same height so that the printing apparatus becomes thinner and is improved in portability. An interior space having a sealed waste ink flow passage for connecting the recovery section to the waste ink absorber is provided, in which a flow passage absorber is accommodated so that a gap is formed from a connection with the discharging port of the pump to a connection with the waste ink absorber and is further connected to the waste ink absorber. Thereby, the waste ink is effectively and securely guided to the waste ink absorber and securely retained there, without leakage.
