• Code: SC505-04
• Description: LCT Tray Error (Paper Overload Error): D709 During tray initialization, the upper limit sensor and the lower limit sensor were both on for 5 times consecutively.
• Causes: • Paper overloaded. • Upper limit sensor defective/connecter disconnected • Lower limit sensor defective/connecter disconnected • Related harness broken • PCB defective
• Remedy: • Reduce loaded paper. • Replace or reconnect the upper limit sensor. • Replace or reconnect the lower limit sensor. • Replace the corresponding harness. • Replace the PCB.

• Code: SC505-11
• Description: LCT Tray Error (Upper Limit Detection Error): D710 At the start of tray initialization, the upper limit sensor was detected as being off for 5 times before the pick-up solenoid was on.
• Causes: • Pick-up solenoid defective/connecter disconnected • Upper limit sensor defective/connecter disconnected • Related harness broken • PCB defective
• Remedy: • Replace or reconnect the pick-up solenoid. • Replace or reconnect the upper limit sensor. • Replace the corresponding harness. • Replace the PCB.

• Code: SC505-12
• Description: LCT Tray Error (Lift timeout): D710 During Tray initialization, the tray bottom plate was lifted but the upper limit sensor did not detect it after a specified time (27 seconds).
• Causes: • Lift motor defective/connecter disconnected • Upper limit sensor defective/connecter disconnected • Related harness broken • PCB defective
• Remedy: • Replace or reconnect the lift motor. • Replace or reconnect the upper limit sensor. • Replace the corresponding harness. • Replace the PCB.

• Code: SC505-16
• Description: LCT Tray Error (front blower fan error): D710 Started LD signal check one second after LCT front blower fan became on and detected H level (abnormal) for 700 ms consecutively.
• Causes: • Front blower fan defective/connecter disconnected • Related harness broken • PCB defective
• Remedy: • Replace or reconnect the front blower fan. • Replace the corresponding harness. • Replace the PCB.

• Code: SC505-17
• Description: LCT Tray Error (rear blower fan error): D710 Started LD signal check one second after LCT rear blower fan became on and detected H level (abnormal) for 700 ms consecutively.
• Causes: • Rear blower fan defective/connecter disconnected • Related harness broken • PCB defective
• Remedy: • Replace or reconnect the rear blower fan. • Replace the corresponding harness. • Replace the PCB.

• Code: SC509-01
• Description: Bypass tray lift error The bottom plate started CW but the tray upper limit sensor did not become blocked within 3 seconds. If detected for the first or second time: User is instructed to set paper again. If detected for the third time: SC displayed The count of detections is reset when successful operation is detected and at power off/on.
• Causes: • Bypass tray upper limit sensor defective/disconnected/harness broken • Bypass tray bottom plate lift motor defective/disconnected/harness broken • Circuit board (PFB) error • Bypass tray bottom plate/bottom plate drive unit does not move e.g. because physical obstacle (broken piece of the unit, etc.) is blocking operation.
• Remedy: • Bypass tray bottom plate lift motor and bypass tray bottom plate upper limit sensor check/cleaning/replacement/harness reconnection/harness replacement • Check or replace the circuit board (PFB). • Check and/or replace the bypass tray bottom plate and bottom plate lift drive unit.

• Code: SC509-02
• Description: Bypass tray lowering error The bottom plate started CCW but the tray upper limit sensor did not become non-blocked within 1.5 seconds. If detected for the first or second time: User is instructed to set paper again. If detected for the third time: SC displayed The count of detections is reset when successful operation is detected and at power off/on.
• Causes: • Bypass tray upper limit sensor defective/disconnected/harness broken • Bypass tray bottom plate lift motor defective/disconnected/harness broken • Circuit board (PFB) error • Bypass tray bottom plate/bottom plate drive unit does not move e.g. because physical obstacle (broken piece of the unit, etc.) is blocking operation.
• Remedy: • Bypass tray bottom plate lift motor and bypass tray bottom plate upper limit sensor check/cleaning/replacement/harness reconnection/harness replacement • Check or replace the circuit board (PFB). • Check and/or replace the bypass tray bottom plate and bottom plate lift drive unit.

• Code: SC509-03
• Description: Bypass tray lower limit error The bottom plate started CCW but the tray lower limit sensor did not become blocked within 3 seconds. If detected for the first or second time: User is instructed to set paper again. If detected for the third time: SC displayed The count of detections is reset when successful operation is detected and at power off/on.
• Causes: • Bypass tray lower limit sensor defective/disconnected/harness broken • Bypass tray bottom plate lift motor defective/disconnected/harness broken • Circuit board (PFB) error • Bypass tray bottom plate/bottom plate drive unit does not move e.g. because physical obstacle (broken piece of the unit, etc.) is blocking operation.
• Remedy: • Bypass tray bottom plate lift motor and bypass tray bottom plate lower limit sensor check/cleaning/replacement/harness reconnection/harness replacement • Check or replace the circuit board (PFB). • Check and/or replace the bypass tray bottom plate and bottom plate lift drive unit.
