Abstract
When a disconnection detecting circuit detects failure, a controller of a temperature controller manipulates a duty ratio to distribute the duty ratio to normal heating rollers. Since the amount of heat decreased by failure of a heating roller can be compensated for by the other heating rollers, no defective drying will occur. It is not necessary to stop a printing process immediately when the disconnection detecting circuit detects failure, but a maintenance operation can be carried out after fully securing a preparation time for maintenance. The quick maintenance can be performed to restrain downtime of the printing apparatus.
