Abstract
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.
Claims14
A recording apparatus comprising:
- dot formation means being divided into a plurality of groups, each of the groups for forming a dot in accordance with a predetermined dot formation condition assigned thereto, the dot formation condition related to monochrome recording or color recording;
- drive means for driving the respective groups in the dot formation means in accordance with record data;
- control means for expanding record information into an image in storage means and for transferring record data from the storage means to the drive means;
- fixing signal output means for outputting a mode fixing signal determining whether the dot is formed or not, and for transmitting the mode fixing signal to the drive means associated with a group in the dot formation means in which whether the dot is formed or not is predetermined as the dot formation condition, instead of the record data;
- mode fixing means for fixing the dot formation condition of the group in the dot formation means, to which the mode fixing signal is transmitted, as determined by the mode fixing signal.
A method of controlling data, comprising the steps of:
- providing a recording apparatus comprising dot formation means being divided into a plurality of groups, each of the groups for forming a dot in accordance with a predetermined dot formation condition assigned thereto, the dot formation condition related to monochrome recording or color recording;
- drive means for driving the respective groups in the dot formation means in accordance with record data;
- and control means for expanding record information into an image in storage means and for transferring record data from the storage means to the drive means;
- judging whether there is a group of the dot formation means in which whether the dot is formed or not is predetermined as the predetermined dot formation condition, when the record data is expanded in the storage means and is transmitted from the storage means to the drive means;
- outputting a mode fixing signal determining whether the dot is formed or not, and transmitting the mode fixing signal to the drive means associated with the group in which whether the dot is formed or not is predetermined, instead of the record data;
- and
- fixing the dot formation condition of the group in the dot formation means, to which the mode fixing signal is transmitted, as determined by the mode fixing signal.
