• Code: SC364-00
• Description: Toner End Sensor output count error When the average value of the toner end sensor output count is 0 n times consecutively (n: SP2-931-003)
• Causes: • Connector contact failure/disconnected/broken • Detector element (sensor) does not emit light • Detecting surface inside the developing device is stained
• Remedy: • Turn the main power off/on.

• Code: SC440-00
• Description: High voltage output error: Transfer unit This SC is issued if the engine board detects a short in the power pack 10 times consecutively.
• Causes: Open circuit (+) / Short circuit (-)
• Remedy: • Turn the main power off/on. • Replace the board • Check the connector connection.

• Code: SC460-00
• Description: High voltage output error: Paper separation This SC is issued if the engine board detects a short 10 times consecutively during PWM signal output of the paper separation.
• Causes: Short Circuit
• Remedy: • Turn the main power off/on. • Replace the board. • Check the connector connection.

• Code: SC498-00
• Description: Temp Humid Sensor error • Temperature Sensor output error: Out of range between 076 V and 2.90 V • Humidity Sensor output error: 2.4 V or more
• Causes: • Unmounted Sensor (Unset connector or broken wire) • Failed Sensor
• Remedy: • Check that the connector is set. • Replace the Sensor.

• Code: SC508-00
• Description: By-pass bottom plate operation error The signal from the by-pass bottom plate HP Sensor has not changed (that is, the signal has not changed from ON to OFF or vice versa) for 4 seconds or more after the start of reverse Paper Feed Unit rotation. If the error is detected three times in succession, the appropriate SC number is displayed on the operation panel unit.
• Causes: • By-pass bottom plate HP sensor connector disconnected or other error • By-pass bottom plate HP sensor feeler stuck or other error
• Remedy: • Check and replace the by-pass bottom plate HP sensor connector connection. • Replace the by-pass bottom plate HP sensor feeler. • Replace the harness. • Replace the engine board.

• Code: SC520-00
• Description: Main motor error When the main motor is driven, the lock (state of rotation) signal is checked every 100 milliseconds. If the machine detects the lock signal in the High status 20 times in succession, it reports this error.
• Causes: • The main motor incurs too much load from a defective unit. • The main motor is defective.
• Remedy: • Turn the main power off/on. • Replace the defective unit or the motor.

• Code: SC525-01
• Description: Tray 2 paper feed motor error When the machine has an optional tray, the lock signal from the paper feed motor in the tray 2 is received.
• Causes: • Paper feed motor in the tray defective • Connector broken or disconnected • Board failure • Mechanical, excessive load against tray driving
• Remedy: • Replace the paper feed motor of the tray. • Replace the harness. • Replace the board. • Replace the tray

• Code: SC525-02
• Description: Tray 2 paper feed motor error When the machine has two optional trays, the lock signal from the paper feed motor in the tray 2 is received.
• Causes: • Paper feed motor in the tray defective • Connector broken or disconnected • Board failure • Mechanical, excessive load against tray driving
• Remedy: • Replace the paper feed motor of the tray. • Replace the harness. • Replace the board. • Replace the tray.
