Abstract
An ink jet recording apparatus modifies backlash correction data in accordance with changes in weight of a carriage, and reduces the printing disturbance due to the backlash by controlling the recording timing on the basis of the modified correction data. Also, a user is notified of the reduced ink remains in the ink jet recording apparatus by the reduced density of a printed image, and at the same time, the apparatus maximizes the number of sheets that can be recorded with the remaining ink in order to prevent any unrecorded data from being lost. Further, an ink jet recording apparatus according to the present invention makes it possible to curtail any ink consumption more than necessary by setting the amount of exhausted ink as required for the execution of a discharge recovery process by counting the number of dischargings at the time of recording a given amount. Also, when controlling power for a recording apparatus, the temperature rise is predicted from the number of drivings at the time of recording on a given area, and when the temperature rise is conspicuous, the driving frequency is reduced in order to suppress the heat generation of the apparatus.
