• Description: Duplex Controller Hardware Error
  The error indicates a problem with the duplex (DUP P.W.B.) and main engine (MCTL P.W.B.) hardware control. Reset the printer power switch. Ensure the harness between the DUP P.W.B. board and the main engine (MCTL P.W.B.) board are connected. If the problem still exists, replace the duplex (DUP P.W.B.) board.
• Remedy: The error indicates a problem with the duplex (DUP P.W.B.) and main engine (MCTL P.W.B.) hardware control. Reset the printer power switch. Ensure the harness between the DUP P.W.B. board and the main engine (MCTL P.W.B.) board are connected. If the problem still exists, replace the duplex (DUP P.W.B.) board.

• Code: 981
• Description: Duplex Motor (DPM1, DPM2) Error
  The error indicates a problem with the duplex motors, DPM1, and DPM2.
• Remedy: 1 Gears, Belts, Rollers Check the duplex drive train for binds or broken gears, belts or rollers. Replace any damaged parts.
  2 • Duplex Motor (DPM1) • Duplex P.W.B. Board Check the resistance of the duplex motors (DPM1). If the resistance is approximately 7 ohms between: • The duplex motor 1 (DPM1) connector CN5-1 and – CN5-2 – CN5-3 – CN5-4 • Replace the duplex (DUP P.W.B.) board. If the resistance is not approximately 7 ohms, replace the duplex motor 1 (DUP1).
  3 • Duplex Motor 2 (DPM2) • Duplex P.W.B. Board Check the resistance for duplex motor 2 (DPM2). If the resistance is approximately 7 ohms between: • The duplex motor 2 (DPM2) connector CN7-1 and – CN7-2 – CN7-3 – CN7-4 • Replace the duplex (DUP P.W.B.) board. If the resistance is not approximately 7 ohms, replace the duplex motor 2 (DPM2).

• Code: 982
• Description: Upper Solenoid (DSOL-U) Error
  This error indicates a problem with the duplex upper solenoid (DSOL-U).
• Remedy: 1 Check Connector Ensure connector, CN8, is connected properly between the duplex upper solenoid DSOL and duplex relay P.W.B. board. Ensure connector, CN1, on the relay P.W.B. board is connected properly with DPCN2 on the duplex P.W.B. board.
  2 • Duplex Upper Solenoid (DSOL-U) • Duplex P.W.B. Board If the problem still exists, replace the duplex upper solenoid DSOU. If this does not correct the problem, replace the duplex P.W.B. board.
