Abstract

PURPOSE: To remarkably shorten the recording time of a recorder for recording a plurality of sheets by detecting whether a plurality of recording units are in usable state or not and selecting the recording units to be used according to the detection and the set number of recording.
CONSTITUTION: No sheet detectors 21W23 are provided in sheet feeding cassettes of respective recording units. Jam detectors 24W26 for detecting the sheet jam are provided in the respective conveying systems 15W17. No ink detectors 27W29 are provided in the respective ink tanks. Trouble signals form these detectors are inputted to a control circuit 18' and are indicated on a trouble indicator 20. A picture data read by a COD circuit 1 is stored in a memory 4 through a digital circuit 2 and a buffer circuit 3. The data are in turn inputted to buffer circuit 6W8 usable by a memory controller 5 controlled by the circuit 18'. The data are then fed to usable recording heads 12W14 via drive circuits 9W11 controlled in ON or OFF by the circuit 18' for recording.
