Abstract:
An image recording apparatus includes a liquid chamber, a first path having a flow resistance R, a second path, a recording head configured such that a predetermined operation of the recording head causes liquid to flow to the recording head at a flow rate greater than or equal to a minimum flow rate I, a pressure responsive portion including a membrane configured to move in response to the internal pressure of the second path and configured to move when a pressure differential between inside and outside of the membrane is greater than or equal to a minimum pressure differential ΔP, a detector configured to detect a position of the membrane, and a controller configured to determine presence of the liquid in the liquid chamber based on detection by the detector. The following condition is satisfied: flow resistance R≧(minimum pressure differential ΔP/minimum flow rate I).
