PURPOSE:To easily decide whether a fault which is generated thereafter is caused by a service life of parts or not by displaying the details of periodical replacement parts on a display part by a replacing signal outputted at the time of replacement of the periodical replacement parts, and printing and recording the details of the periodical replacement parts on a printing form by a printing control part. CONSTITUTION:When periodical replacement parts reach the time of replacement, a replacing signal Vs is outputted from a replacement period managing part 1, and inputted to a display part 2 and a printing control part 3. The display part 2 displays the details of the replacement parts by the replacing signal Vs, and the printing control part 3 prints the details of the replacement parts on a printing form by the replacing signal Vs. Accordingly, when the periodical replacement parts reach the time of replacement, the details of the replacement parts are recorded on the printing form. In such a way, whether a fault generated in the course of the subsequent printing operation is caused by a service life of the periodical replacement parts or not can be decided easily. |
