Abstract
A facsimile apparatus employs an ink jet printer in which the ink discharge recovery operation by idle ink discharge from all the discharge openings of the recording head is conducted at a suitable timing instructed by a central processing unit. The timing of the idle ink discharge is determined not by a timer interruption procedure, which imposes an additional burden on the processing capacity of the central processing unit, but from the image data receiving rate and the amount of actually received data. In this manner the central processing unit can provide increased processing capacity, and the control program can be simplified and made less expensive.
