Abstract
A recording apparatus includes a recording head which is scanned, a supply system containing an amount of ink and a detector for the residual ink quantity in the supply system. The residual ink quantity is detected by detecting deviation of a deviation member; this deviation occurs upon a change in pressure in an ink supply path in the ink supply system. The detection is performed after a predetermined time delay with respect to a signal relating to a change of scan direction or with respect to operation of a pump.
