The carriage 2 is returned to the standby position (S109), and is in a command standby state.
Return. If the value of ID2 is 0, ie,
If nothing is mounted on ridge 2, the same as before
As described above, the carriage 2 is returned to the standby position as it is (S10).
9) Return to the command waiting state. If the value of ID2 is 2, ie,
When the one mounted on the ridge 2 is the scanner 6
Is the initial scan required for image reading as in the conventional example.
The carriage correction operation is performed (S110), and the carriage 2 is moved to the standby position.
(S109), and enters the command waiting state to end the operation.
Complete. Recording with the image reading function of this embodiment
The device is mounted on the carriage 2 as described above.
Is changed from the scanner 6 to the recording head 1,
Suction recovery operation of quality maintenance operation that is not always necessary
Is not performed, so that the reading process by the scanner 6 is not performed.
Without wasting time, and for suction recovery
Consumption of extra ink due to
You. Although the present invention has been described in detail, the gist of the present invention is as follows.
Various improvements and modifications can be made without departing from the scope
Needless to say. For example, in the above embodiment,
Only the suction recovery operation was omitted from the work, but other product holding operations
Is omitted when the scanner 6 is replaced with the recording head 1.
It is also possible. Specifically, in addition to the suction recovery operation,
In addition, omitting the wiping operation and the preliminary ejection operation
It is easy to do this just before the recording (printing) starts.
In the case of (1), a further time reduction effect can be achieved. The present invention is particularly applicable to an ink jet recording system.
Above all, flying droplets are formed using thermal energy,
Inkjet recording heads and recording devices
It has an excellent effect. For the representative configuration and principle, for example,
