Abstract
A recording apparatus comprises a recording head for forming an image on a recording medium, a carriage for holding the recording head, capable of scanning in a main scanning direction, and a carrying mechanism for carrying the recording medium in a sub-scanning direction, wherein even with shift of the position of the carriage before scanning, scanning of the carriage is carried out after the carriage is located at a start position, or wherein a difference of the start position of the carriage upon each scanning is arranged to be a distance equal to an integral multiple of one period of phase of motor.
Claims13
A recording apparatus that performs recording using a recording head, said apparatus comprising:
- a carriage for mounting and reciprocally moving the recording head;
- a stepping motor for driving said carriage;
- and
- a control unit for controlling a distance between a first start position of said carriage, where a previous line is recorded, and a second start position of said carriage, where a next line is recorded, to correspond to an integer multiple of one period of a phase of said motor.
A recording method applied to a recording apparatus that performs recording using a recording head, said method comprising the steps of:
- providing a carriage for mounting and reciprocally moving the recording head;
- providing a stepping motor for driving the carriage;
- determining a start position of the carriage for each recording operation corresponding to one scan of the recording head on a recording medium, based on recording data;
- and
- controlling a start position of the carriage for a next scan so that a distance between a start position of the carriage for a previous scan and a start position of the carriage for the next scan corresponds to an integer multiple of one period of a phase of the motor, in accordance with the start position of the carriage for the previous scan.
A recording apparatus the performs recording using a recording head, said apparatus comprising:
- a carriage for mounting and reciprocally moving the recording head;
- a stepping motor for driving said carriage;
- and
- a control unit for controlling said motor so that a phase of said motor at a first start position of said carriage, where a previous line is recorded, and a phase of said motor at a second start position of said carriage, where a next line is recorded, are a same phase.
