4227-300 Tractor 2 service check The Tractor 2 sensor opens during installation, when its actuator touches the printer cover. The home sensor detects the position of the slider. • When Tractor 2 is selected, the motor-driven Tractor 2 slider pushes the printer sub slider cam lever to engage the printer gear train, which drives the Tractor 2 tractors. • When the Tractor 2 is deselected, the motor retracts the slider, disengaging the Tractor 2 gear drive and reengaging the printer tractors. 63D Tractor 2 HP error The Tractor 2 Home sensor was never initialized after turning the printer off and then on, or made at the wrong time. (The same error indication is used for carrier home failure.) FRU 1 Tractor 2 Home Sensor Action Remove the Tractor 2 and turn the printer off and then back on again to determine whether the fault is in the printer or in Tractor 2. If the gear teeth chatter just before the error is displayed, replace the home sensor. Diagnostic information 2-31
