• Code: SC403-04
• Description: Development Start Voltage (Vk) High Error (Y). 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: SC404-01
• Description: Development Start Voltage (Vk) Low Error (K). Development Start Voltage (Vk) < 300 [-V] Details: This SC is issued when the development start voltage measured during process control was smaller than 300[-V].
• Causes: • Toner density error • Condensation
• Remedy: • Replace the developer. • If condensation has formed, wait a while and repeat process control.

• Code: SC404-02
• Description: Development Start Voltage (Vk) Low Error (C). Development Start Voltage (Vk) < 300 [-V] Details: This SC is issued when the development start voltage measured during process control was smaller than 300[-V].
• Causes: • Toner density error • Condensation
• Remedy: • Replace the developer. • If condensation has formed, wait a while and repeat process control.

• Code: SC404-03
• Description: Development Start Voltage (Vk) Low Error (M). Development Start Voltage (Vk) < 300 [-V] Details: This SC is issued when the development start voltage measured during process control was smaller than 300[-V].
• Causes: • Toner density error • Condensation
• Remedy: • Replace the developer. • If condensation has formed, wait a while and repeat process control.

• Code: SC404-04
• Description: Residual Voltage (Vr) Detection Error (K). Development Start Voltage (Vk) Low Error (Y). Development Start Voltage (Vk) < 300 [-V] Details: This SC is issued when the development start voltage measured during process control was smaller than 300[-V].
• Causes: • Toner density error • Condensation
• Remedy: • Replace the developer. • If condensation has formed, wait a while and repeat process control.
