When the recording start position of the recording medium 202 or 205 reaches below the black recording head 309K while transporting the 205 (cut paper), the ejection of black ink is started.
[0054]
Similarly, when the recording medium 202 or 205 reaches the recording start position in the order of the recording heads 309C, 309LC, 309M, 309LM, and 309Y, ink of each color is ejected to perform color recording.
[0055]
Below the recording medium transport mechanism 201, an ink cartridge 203 storing ink to be supplied to the recording heads 309K to 309K is provided.
[0056]
The operation of the mechanism described above and the control described above are executed by a control circuit (FIG. 3) having a CPU and the like.
[0057]
FIG. 3 is an electrical block diagram of the recording apparatus 100 embodying the present invention.

The paper replacement is detected, for example, when the user finishes the paper replacement and presses an ONLINE key or the like on the operation panel (not shown).
[0094]
Further, the operation proceeds again after the paper is replaced in step s517, and the flag indicating that the remaining number is insufficient is cleared in s509.
[0095]
Next, the case where communication is not possible in step 501 will be described. After turning on an error flag to check whether it is an accidental error (s519), retry is performed. When the number of retries reaches the predetermined nth time, desired recording is performed. It is determined that the medium is not set correctly, and an alarm is transmitted (s521).
[0096]
After the retry, if the communication can be normally performed, the error flag is released in s502.
[0097]
