Tractor 2 Paper Feed Problems
FRU Action
1 Tractor 2 Be sure the gear on the printer that drives
Tractor 2 turns freely when the lever is not
pressed, but remains still when the lever is
pressed.
Remove the Tractor 2 unit from the printer and
remove all paper. With the paper select lever in
the continuous forms position, press
FormFeed; the tractors should rotate. Press
the sub slider cam lever below the ASF/Tractor
2 drive gear and press FormFeed again; the
tractors should not rotate but the drive gear
should.
Check the condition of the pin feed belts. With
the printer off and be 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.
2 Tractor 2 Cover Remove the Tractor 2 cover and reinstall the
Tractor 2 unit 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
tends 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.

connectors, go to “Signal Connections” on
page 5-2.
