Abstract:
1. A recording apparatus comprising: a transporting mechanism configured to transport a recording medium along a first transporting path; a recording head configured to record an image on the recording medium which is transported by the transporting mechanism; a reading unit which is configured to read the recording medium and which is arranged upstream of the recording head along the first transporting path and on a side opposite to the recording head, with the first transporting path intervened between the reading unit and the recording head; a re-transporting mechanism configured to re-transport the recording medium to return to an upstream portion of the first transporting path located upstream of the reading unit with a rear end, of the recording medium which has been transported by the transporting mechanism to a downstream portion of the first transporting path located downstream of the recording head, as a forward end in the re-transportation, via a second transporting path different from the first transporting path, thereby performing re-transportation of the recording medium to an upstream portion, of the transporting mechanism, located upstream of the reading unit in a state that front and back surfaces of the recording medium are inverted; a sensor arranged upstream of the recording head along the first transporting path and configured to detect a forward end of the recording medium which is transported by the transporting mechanism; and a controller configured to control the recording head, the reading unit, the transporting mechanism and the re-transporting mechanism, wherein the controller is configured to execute: a test pattern recording process in which a test pattern is recorded on a first surface of the recording medium based on a detection timing at which the sensor detects the forward end of the recording medium by controlling the transporting mechanism and the recording head; a first reading process, in which the recording medium having the test pattern recorded on the first surface thereof is re-transported to the reading unit by controlling the re-transporting mechanism and the transporting mechanism and the first surface on which the test pattern has been recorded is read by controlling the reading unit; a re-test pattern recording process, in which a re-test pattern is recorded by controlling the transporting mechanism and the recording head, at a recording corrected based on a reading data read in the first reading process, on a second surface on a side opposite to the first surface of the recording medium based on the detection timing, before the recording medium which has been read in the first reading process completely passes beyond the recording head for a first time after the first reading process; and a second reading process, in which the recording medium having the re-test pattern recorded on the second surface thereof is re-transported by controlling the re-transporting mechanism and the transporting mechanism and the second surface on which the re-test pattern has been recorded is read by controlling the reading unit.
