4512-220, -230 Service error codes Service error codes are generally non-recoverable except in an intermittent condition when POR is performed and the printer can temporarily recover from the error condition. Service error codes (9xx) Error Description Engine software service errors 902.xx Engine software error Transfer service errors 917.00 Transfer service error 917.01 Transfer servo result too low. Fuser service errors 920.00 Under temperature during steady state control. 920.01 Fuser took too long to heat up after transitioning to new enhanced mode. 920.02 Fuser fell too far below desired temperature while printing. 920.03 Fuser too cool while checking for slope change. 920.04 Fuser too cool when heating to desired temperature after slope change. 920.05 Fuser under temperature while printing 920.06 Fuser under temperature while printing 920.07 Fuser under temperature while printing 920.08 Fuser temperature did not increase after IR recovery. 920.20 Belt fuser under temperature during steady state control. This can occur in printing or standby modes. 921.00 Under temperature during standby control. 921.01 Fuser temperature did not reach standby temperature after two attempts 922.00 Fuser failed to ramp to target temperature 922.01 Fuser did not reach standby temperature in time (standby control) 922.06 Fuser did not reach ioerating temperature in time (new enhanced control). 922.07 Media reached fuser nip and fuser is under temperature 922.08 Fuser warm-up failure (motor start condition) 922.09 Fuser warm-up failure (compression set) 922.20 Belt fuser failed to reach the preheat temperature for the motor to start during warm-up. 922.21 Belt fuser was under temperature when the media reached the fuser nip. 923.00 Fuser is over temperature. 923.01 Fuser is over temperature. This applies to the fuser and belt fusers. 924.00 Open thermistor check. Diagnostic information 2-33
