• Code: SC402-54
• Description: Development gamma calculation error: Insufficient data (Y). The number of valid data that can be used for development gamma calculation is smaller than 2.
• Causes: • Toner density error • Condensation
• Remedy: • Replace the developer. • If condensation has formed, wait a while and repeat process control.

• Code: SC402-61
• Description: Development gamma calculation error: LD unlit (K). Unable to draw gradation pattern Details: This SC is issued when the potential sensor fails to detect the gradation pattern created during process control.
• Causes: • LD unlit
• Remedy: • Check the LD system and electric components.

• Code: SC402-62
• Description: Development gamma calculation error: LD unlit (C). Unable to draw gradation pattern Details: This SC is issued when the potential sensor fails to detect the gradation pattern created during process control.
• Causes: • LD unlit
• Remedy: • Check the LD system and electric components.

• Code: SC402-63
• Description: Development gamma calculation error: LD unlit (M). Unable to draw gradation pattern Details: This SC is issued when the potential sensor fails to detect the gradation pattern created during process control.
• Causes: • LD unlit
• Remedy: • Check the LD system and electric components.

• Code: SC402-64
• Description: Development gamma calculation error: LD unlit (Y). Unable to draw gradation pattern Details: This SC is issued when the potential sensor fails to detect the gradation pattern created during process control.
• Causes: • LD unlit
• Remedy: • Check the LD system and electric components.

• Code: SC403-01
• Description: Development Start Voltage (Vk) High Error (K). Development Start Voltage (Vk) > 300 [-V] Details: This SC is issued when the development start voltage measured during process control exceeded 300[-V].
• Causes: • Toner density error
• Remedy: • Replace the developer.

• Code: SC403-02
• Description: Development Start Voltage (Vk) High Error (C). Development Start Voltage (Vk) > 300 [-V] Details: This SC is issued when the development start voltage measured during process control exceeded 300[-V].
• Causes: • Toner density error
• Remedy: • Replace the developer.

• Code: SC403-03
• Description: Development Start Voltage (Vk) High Error (M). Development Start Voltage (Vk) > 300 [-V] Details: This SC is issued when the development start voltage measured during process control exceeded 300[-V].
• Causes: • Toner density error
• Remedy: • Replace the developer.
