Abstract
A recording head having a plurality of recording elements arranged thereon is moved in a different direction than a direction of arrangement to make record scan and a recording sheet is fed by a distance corresponding to a recording width of the recording head for each scan. The record scan (main scan) and the sheet feed (sub-scan) are repeated to record received image data on the recording sheet. The feed amount of the recording sheet is counted, and the data is sent to a recording unit until the count reaches a predetermined count, that is, the data a predetermined amount before a trailing edge of the recording sheet is sent, without synchronization with the operation of the recording unit. Thereafter, when the recording of the sent-out data is completed, the remaining data is sent for each record scan in synchronism with the operation of the recording unit During the period other than the recording operation period, the detection of the trailing edge of the recording sheet is monitored by a sensor provided before a recording position. When the trailing edge of the recording sheet is detected, whether the remaining data is recordable or not is determined bases on the count, and if it is recordable, the process is continued and if it is not recordable the renewal of page is made.
