Claims7
A recording apparatus comprising:
- first sheet feeding means for feeding a large size of recording sheet;
- first detection means for detecting the presence or absence of a sheet in said first sheet feeding means;
- second sheet feeding means for feeding a small size of recording sheet;
- second detection means for detecting the presence or absence of a sheet in said second sheet feeding means;
- communication means for data communication;
- recording means for recording image data received from said communication means or communication monitoring data;
- and
- selection means for selecting either one of said first and second sheet feeding means, in the recording of the received image data, in accordance with size data transmitted to said communication means prior to said image data, and for selecting said second sheet feeding means in the recording of said communication monitoring data, said selection means selecting said first sheet feeding means in the recording of said communication monitoring data when said second detection means detects the absence of a sheet and said first detection means detects the presence of a sheet.
