Abstract
An ink jet recording apparatus detects loading of an ink cartridge into a loading portion based on information allocated to the cartridge. The cartridge carries characteristic information including information about manufacturing time of the cartridge. A recovery operation is executed by a discharge recovery device with the recovery operation being determined based on a time difference between the manufacturing time of the cartridge and the loading time when the cartridge is loaded into the loading portion.
