Logic board
Remove Tractor 2 from the printer, but leave
the cable connected. Be sure the slider (the
black plastic piece just above the right cover)
moves after turning the printer off and then
back on.
If the slider does not move after turning the
printer off and then back on:
• Be sure the slider and gear train are properly
connected and move freely with the power
off.
• Be sure the Tractor 2 board is receiving:
+40 V dc on CN1-1 and +5 V dc on CN1-5.
If the slider does move, check the cable
connection and the voltages at logic board
CN10-1. The upper right pin at CN10 is pin 1
(+40 V dc) and the pin just beneath it is pin 5
(+5 V dc).
If these voltages are not present, replace the
logic board.

Tractor 2 motor
board/cable
assembly
Check the resistances of the Tractor 2 motor
windings at CN5 on the Tractor 2 board. There
should be 101 ± 5 ohms between pins:
CN5 -1 and CN5 - 4
CN5 -1 and CN5 - 6
CN5 -2 and CN5 - 3
CN5 -2 and CN5 - 5
If the motor is good, replace the board/cable
assembly.

connectors, see
