PURPOSE:To eliminate troubles and mismemory of instructions by discharging a cut paper staying in a conveying path of a recorder when the recorder detects a specific state of a control section. CONSTITUTION:When a key is pressed to generate a power ON reset or remove the abnormal state, a GNRST signal from a controller turns to TRUE. When the power source is switched OFF and GNRST checking routine D and the CPRDY checking routine E detects that the CPRDY signal turns to FALSE, the operation exits the circulation loop and jumps to a routine K. In the routine K, the contents of an RAM memorizing the command previously received from the controller are cancelled by a routine F. In the routines G, H, I, J and L, a CPU provides a signal to a paper conveying motor which is to drive a paper feed roller, a conveying roller and a fixing roller simultaneously for a specified time length. During the driving, a photosensor detects a paper and provides the detection signal to the CPU, which drives a paper delivery roller to discharge the paper staying. |
