• Code: SC371-02
• Description: ID sensor output error (C). The ID sensor voltage reading of the light reflected directly (Vsg_reg) is below 0.5 V.
• Causes: • ID sensor connector disconnected/loose connection • ID sensor defective
• Remedy: • Check if the ID sensor connector is connected. Connect it if disconnected. • Replace the ID sensor if defective.

• Code: SC371-03
• Description: ID sensor output error (R). The ID sensor voltage reading of the light reflected directly (Vsg_reg) is below 0.5 V.
• Causes: • ID sensor connector disconnected/loose connection • ID sensor defective
• Remedy: • Check if the ID sensor connector is connected. Connect it if disconnected. • Replace the ID sensor if defective.

• Code: SC372-01
• Description: ID sensor LED current upper limit error (F). The ID sensor LED current exceeds the upper limit (SP3-320-015)
• Causes: • ID sensor smudged • ID sensor deteriorated • ITB deteriorated (smudges, filming)
• Remedy: • Check the ID sensor window. Wipe it with a damp cloth if dirty (never use dry cloth). • If the ID sensor is deteriorated, replace it. • If the ITB is smudged, check the ITB unit.

• Code: SC373-01
• Description: ID Sensor Pattern Density High Error (K). K: The density of the Black reading in the ID sensor patterns created between pages (SP3-300-001) is greater than the threshold value set by SP3-301-021. CMY: The density of the Cyan/Magenta/Yellow reading in the ID sensor patterns created between pages (SP3-300-002 to o004) is greater than the threshold value set by SP3-301-022.
• Causes: • Excessive toner supply
• Remedy: • Replace the toner supply unit.
