Abstract
A recovery process starting unit extracts a low print demand period, and sets the extracted low print demand period as the start time for the print head recovery process. When the start time comes, the recovery process starting unit activates the head recovery drive control unit. When the start signal is received from the recovery process starting unit, the head recovery drive control unit operates the ink vacuum mechanism and head wiping mechanism of the recovery process unit by means of a drive, and runs the print head recovery process.
