Title: Recorder
Inventor: TAKAHASHI KAZUYOSHI
IPC: G03G15/20
Filed: 1990-09-27
Abstract: PURPOSE:To perform recording on a recording material other than a normal sheet regardless of presence of a fixing device by a method wherein recording is performed regardless of provision of the fixing device even in the case the recording material is not normal sheet. CONSTITUTION:When a fixing device 20 is mounted and an OHP sheet is used, recording action takes place after a tension roller 17 is released. When a sheet of normal paper is used, recording action is started as it is. On the other hand, when the fixing device 20 is not mounted, absence of the fixing device 20 is indicated. When the OHP sheet is used, recording action takes place after the tension roller 17 is released, and when the normal paper is used, recording action takes place as it is. Therefore, recording can be performed on the OHP sheet regardless of presence of the fixing device 20. When the fixing device 20 is provided, it becomes unnecessary to wait for ink to dry after recording is finished.
