Abstract
A facsimile apparatus which prints a received image using ink, and which can perform residual-ink detection and verification of detection result with simple construction. The apparatus judges whether or not the ink is exhausted, based on a detected pulse width from a photosensor for determining existence/absence of the ink. If the result of the residual-ink detection is not reliable, the apparatus examines again the detected pulse from the photosensor when actual ink discharge operation is not performed. If the result of the re-examination is different from an expected result, the apparatus notifies a message indicating an occurrence of abnormality on an LCD.
