• Code: SC720-24
• Description: Paper Exit Open/Close Guide Plate Motor Error (2K/3K sheet finisher) • Motor driver detects an error (short-circuit/ overheating) (1st time, SC). • During movement to home, the home position could not be detected within a predetermined pulse (p0 pulse) (1st time is jam notification, 2nd time is SC notification). • During movement from home, the home position was detected for longer than a predetermined pulse (p1 pulse) (1st time is jam notification, 2nd time is SC notification). The return pulse to home and pulse coming from home during normal operation are calculated and measured. The pulses which are 1.5-2 times the normal operation pulse are taken as p0 and p1.
• Causes: • Motor defective • Connector disconnected • Overload • Encoder defective (*SC720-25 only) • Home position sensor defective
• Remedy: • Check the motor • Check the home position sensor connection • Replace the motor • Replace the home position sensor • Replace the main board of the finisher
