Causes: 100 The AF read sensor adjustment error. 101 AF-EEPROM error. 110 ABC (auto-base-control) timeout. The original does not move from the ABC scanning position on the AF unit. 111 Operation command was made to the AF unit without 24 volts supplied to the AF unit. 130 Timeout error in receiving reply from the AF unit after command signal was sent from the Riso printer to the AF unit. 131 Riso printer received an undefined command from the AF unit. 132 Riso printer detected communication sequence error from the AF unit. 133 Communication error with AF unit (ACK, NAK, or receiving channel error). 134 Riso printer could not send command to the AF unit within the set time. 161 AF unit not connected.
Remedy: Turn the power OFF and ON.
Code: T17
Description: Solenoid counter not connected
Causes: 020 The Solenoid counter is not connected.
Remedy: Connect the Solenoid counter.
Code: T18
Description: Drum-lock solenoid lock
Causes: 531 The Print drum lock sensor is still ON even after 100 milliseconds after the Print drum lock solenoid is activated.
Remedy: Press the <RESET> key.
Code: T19
Description: Thermal-pressure motor lock
Causes: 207 The Thermal pressure sensor does not go OFF within 2 seconds after the Thermal pressure motor activates in the decompressing direction, or during home positioning operation. 208 The Thermal pressure sensor does not go ON within 2 seconds after the Thermal pressure motor activates in the decompressing direction. 216 The Thermal pressure sensor does not go OFF within 2 seconds after the Thermal pressure motor activates in the compressing direction. 217 The Thermal pressure sensor does not go ON within 2 seconds after the Thermal pressure motor activates in the compressing direction.
Remedy: Press the <RESET> key.
Code: T20
Description: Paper-ejection-section motor lock
Causes: 414 The paper ejection wing HP sensor status does not change within set time after the Paper ejection wing motor activated for the wing home position movement. 415 The paper ejection wing HP sensor does not change from OFF to ON even though the Paper ejection wing pulse motor is activated for a given time. 416 Overload current was detected in the Paper ejection motor. 437 The Paper ejection motor FG sensor pulse count dropped to 50% of the set speed. (The detection starts 200 milliseconds after the Paper ejection motor is activated.) 442 Though the Paper ejection wing pulse motor stopped correctly at the sensor stop mode, the stopping position does not correspond with the programmed position. 456 The Paper ejection wing pulse motor does not end its operation within the set period in the pulse count stop mode, or in the sensor stop mode after the actuator is detected by the sensor.
Remedy: Press the <RESET> key.
Code: T24
Description: Inking motor lock
Causes: 539 The Inking motor FG sensor status does not change within 20 milliseconds after the Inking motor is activated.
