• Code: E017-0003
• Description: ETB HP error
  Engagement of the ETB was not completed at initialization.
• Remedy: If this error occurs at installation, the ETB Disengage Member (Transfer Frame Stopper) may be left unremoved. Refer to the troubleshooting "Remedy to be implemented when the ETB Disengage Member (Transfer Frame Stopper) is left unremoved" in the Service Manual, and check whether the ETB Disengage Member is left unremoved or not and implement appropriate procedure. If this error occurs at times other than installation, follow the following steps to implement check and remedy. 1. Check the connection of the ETB Disengage Sensor (PS56). Sensor side: J2101, J3270, PCB side: J343 (Duplex Driver PCB (PCB4)) 2. Check the connection of the Duplex Feed Left Motor (M19).
