摘要:
An ink jet recording apparatus comprises a driving circuit for sequentially supplying drive signals according to recording information and an ink jet recording head that deposits ink onto a recording medium in response to the drive signals. The apparatus determines if the supply of drive signals has been interrupted for a predetermined time period. If so, when the supply of drive signals resumes, a recording control circuit increases the energy of a predetermined number of drive signals. With this arrangement, the recording density can be maintained uniform, even if there are gaps in the recording information.
