Abstract
A driving condition setting method of an ink jet recording head enables stable discharge of an ink drop irrespective of a difference in a channel volume. In a thermal ink jet recording head, the displacement of a distance (channel volume) from a heating element to a nozzle surface is stored as data into a memory. The ink jet recording head is mounted on an ink jet recording device. A control unit of the ink jet recording device reads the data so as to set a driving condition (the number of pre-pulses) of the heating element based on the data. Therefore, even when the channel volume is displaced by a production error, an ink discharge state can be almost constant, and stable printing performance can be ensured.
Claims12
A driving condition setting method of an ink jet recording head having an individual channel in which a heating element is placed for heating ink to produce a bubble and an ink discharge portion at an edge of the individual channel, the method comprising:
- setting a driving condition of the heating element corresponding to a difference in a channel volume of the individual channel from the heating element to the discharge portion due to a production error.
An ink jet recording head comprising:
- an individual channel in which a heating element is placed for heating ink to produce a bubble;
- an ink discharge portion at an edge of the individual channel;
- and
- a data holding unit that stores channel volume data based on a channel volume of the individual channel from the heating element to the ink discharge portion.
An ink jet recording device comprising:
- a driving condition setting part which reads, when an ink jet recording head is mounted to the device, channel volume data of the ink jet recording head to set a driving condition of a heating element of the ink jet recording head, wherein the ink jet recording head comprises:
- an individual channel in which the heating element is placed for heating ink to produce a bubble;
- an ink discharge portion at an edge of the individual channel;
- and
- a data holding unit that stores the channel volume data based on a channel volume of the individual channel from the heating element to the ink discharge portion.
