<p>A serial recording apparatus is disclosed which is capable of continuously printing even if a dot-forming element (or elements) of the element array of the recording head is defective, by substituting for the defective dot-forming element, a substitution dot-forming element. The serial recording apparatus also automatically detects a defective dot-forming element of the element array of the recording head. In operation, print data of the defective dot-forming element, which loses its dot-forming function, is saved in a second print-data storing device, and a first printing pass is carried out. In the second printing pass, a normal dot-forming element is moved to a location on a recording sheet which would otherwise be subjected to printing by the defective dot-forming element, and reads out the print data from the second print-data storing device to print it on that location. <IMAGE></p> |
