Paper Feed Problems FRU 1 Tractor 2 Action On the printer, make sure the gear that drives Tractor 2 turns freely when the lever is not pressed, but remain still when the lever is pressed. Remove Tractor 2 from the printer and remove all paper. With the paper select lever in the continuous forms position, press Line Feed; the tractors should rotate. Press the sub slider cam lever below the ASF/ Tractor 2 drive gear and press Line Feed again; the tractors should not rotate but the drive gear should. Check the condition of the pin feed belts. With the power off, make sure the slider does not bind. Verify: • When the slider is to the rear, the white gear drives the tractors; • When the slider is to the front the gear and tractors are not connected. Remove the Tractor 2 cover and reinstall Tractor 2 in the printer (if necessary remove the printer covers also). Note that the small idler gear just below the slider is held in place by the cover; with the cover removed it will tend to move off the stud. Also note that when operating the Tractor 2 with the printer cover removed, the Tractor 2 in-place sensor must be held open. Turn the printer on and look for mechanical problems. For information on the Tractor 2 cable connectors, see "Tractor 2 Cable Connectors" on page 5-4. Diagnostic Information 2-43
