Recording apparatus and data control method therein

摘要

In an ink jet recording apparatus 1, a fixing signal output section 461 outputs a signal indicating that no ink drop is jetted as a mode fixing signal SP to a head driver circuit 50 for nozzle orifices 111 belonging to the group not used for recording, and a mode fixing circuit 18 of the head driver circuit 50 fixes the nozzle orifices belonging to the corresponding group to a condition of jetting no ink drops based on the mode fixing signal SP. Therefore, serial conversion and serial transfer of the data indicating that no ink is jetted ("0" data) as record data SI need not be executed for the group of jetting no ink drops, so that fruitless processing time can be eliminated.
