CÓPIA NÃO CONTROLADA
Item
Possible Cause/Required Action
• Color development motor slip due to the increase
of the load torque
1. Adjust the load torque properly by replacing or
cleaning the development unit.
2. Replace or repair the development motor if the
load torque is normal.
• Defective connector connection
• Increasing toner density
1. Replace the PCU.
• Defective connector connection
• Decreasing toner density
1. Replace the PCU.
• Defective connector connection
• Defective TD sensor
• The toner density in the developer is different
from the initial condition.
1. Replace the PCU.
