• Code: SC348-01
• Description: Toner supply error (K). K: Amount of toner on the ID sensor pattern printed and read between sheets (SP3-300-001) is less than the lower threshold (SP3-301-023) and accumulated toner clutch ON time (SP3-301-041) is greater than the upper threshold (SP3-301-031). CMY: Amount of toner on the ID sensor pattern printed and read between sheets (SP3-300-002 to 004) is less than the lower threshold (SP3-301-024) and accumulated toner clutch ON time (SP3-301-042 to 044) is greater than the upper threshold (SP3-301-031). Details: This SC is issued when the toner end sensor continues detecting the presence of toner falsely.
• Causes: • Toner end sensor cleaner spring broken • Toner end sensor cleaner spring not set correctly • Toner end sensor defective
• Remedy: • Replace the toner supply unit.

• Code: SC351-01
• Description: Development sleeve home position signal detection error (K). Cannot detect the home position signal within specified time.
• Causes: • Home position sensor defective/loose connection/harness damaged/Connecter disconnected • Home position sensor smudged
• Remedy: • Check if the home position sensor connector is connected correctly. • Check the home position sensor for abnormality. • Replace the home position sensor if it is abnormal. • Check the sensor for smudges. Blow it with air and check again.

• Code: SC351-02
• Description: Development sleeve home position signal detection error (C). Cannot detect the home position signal within specified time.
• Causes: • Home position sensor defective/loose connection/harness damaged/Connecter disconnected • Home position sensor smudged
• Remedy: • Check if the home position sensor connector is connected correctly. • Check the home position sensor for abnormality. • Replace the home position sensor if it is abnormal. • Check the sensor for smudges. Blow it with air and check again.

• Code: SC351-03
