• Code: SC373-04
• Description: ID Sensor Pattern Density High Error (Y). 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.

• Code: SC374-01
• Description: ID Sensor Pattern Density Low Error (K). K: The density of the Black reading in the ID sensor patterns created between pages (SP3-300-001) was less than the threshold value set by SP3-301-023 three times consecutively. CMY: The density of the Cyan reading in the ID sensor patterns created between pages (SP3-300-002 to 004) is less than the threshold value set by SP3301-24 three times consecutively.
• Causes: • Abnormal development bias (Continuity fault) • Image transfer error
• Remedy: • Check development bias continuity. • Check the image transfer unit.

• Code: SC381-01
• Description: Potential sensor output high error (K). Vd(700) greater than 800[-V] Details: In Vd detection, which is done at the beginning of process control, the measured potential (Vd) is converted to the potential when -700 V is applied to the drum (Vd700) and used to check the potential sensor.
• Causes: Potential sensor dirty (foreign object, such as toner, entering the probe window) / potential sensor probe connector disconnected
• Remedy: • Check if the potential sensor probe is clean. If it is dirty, blow it with air and then check again. If this does not work, replace the potential sensor. • Potential sensor probe connector is disconnected.
