Abstract
A facsimile apparatus is equipped with an ink jet printer in which the recording head is inspected for ink discharge failure in response to a call signal, then a head recovery process is effected in case of discharge failure, and the normal data reception process is started after the discharge failure is rectified. If the discharge failure is not rectified after repeated recovery processes, the communication is interrupted, so that wasted communication resulting from malfunction of the recording head can be avoided.
