If no problem is found, replace the STM PWB. (PL 10.6)

• Code: 072-105
• Description: Regi Sensor On Jam (Tray 2) During paper feed from Tray 2, the Regi Sensor did not turn ON within the specified time after the Feed Out Sensor 2 On.
• Remedy: Check the following: • The Regi Sensor (Input Check [071-105]) for operation failure. (PL 15.1) • The STM Take Away Motor (Output Check [072-007] for operation failure. (PL 10.6) • The STM Take Away Roll Clutch (Output Check [072-005] for operation failure. (PL 10.6) • The T/A Roll 2, Feed Roll, and Pinch Roll for transportation failure due to contamination, wear, and deterioration. • The Drive Gear for wear and damage. • A paper transportation failure due to foreign substances on the paper path. • Usage of out of spec paper. If no problem is found, replace the following parts in sequence: • ESS/MCU PWB (PL 18.3) • STM PWB (PL 10.6)

• Code: 072-210
• Description: Tray 2 Lift Up Fail Any of the following was detected: • A Tray 2 Lifter error. • A Tray 2 Paper Size detector component malfunction
• Remedy: Check the following: • The Tray 2 Nudger Level Sensor (Input Check [072-105] for operation failure. (PL 10.3) • The Tray 2 Feed/Lift Motor (Output Check [072-009] (Lift Up) for operation failure. (PL 10.3) • The drive system between the Bottom Plate and the Tray 2 Feed/Lift Motor for operation failure. • The Tray for Paper misload • The Tray for existence of objects other than Paper. If no problem is found, replace the STM PWB. (PL 10.6)

• Code: 072-212
• Description: Tray 2 Size Sensor Broken Abnormal output AD value from Tray 2 Paper Size Switch was detected.
• Remedy: Check the following: • Broken link and damage at the bottom of the Tray • The Actuator at the rear of the Tray for operation failure • The Tray 2 Paper Size Switch (Analog Monitor [072-051], Output Check [072-107] for operation failure. (PL 10.1) • The Tray for Paper misload • The Tray for existence of objects other than Paper. If no problem is found, replace the STM PWB. (PL 10.6)

• Code: 072-215
• Description: MCU-STM Communication Fail Communication failure between the ESS/MCU PWB and the STM PWB was detected.
• Remedy: 1. Turn the power OFF and ON. 2. Turn OFF the power and check the connection between the ESS/MCU PWB J413 and the STM PWB J541C for open circuit, short circuit, and poor contact. 3. If no problem is found, replace the following parts in sequence: • STM PWB (PL 10.6) • ESS/MCU PWB (PL 18.3)
