Installing the Tractor Unit

To install the removable tractor unit, first pull the printer’s friction lever toward the front of the printer. Open the dust cover to provide better access.

Then hold the tractor with the gears to the right as shown in Figure E-3. Slip the tractor into the two slots on the printer.

In each tractor slot are two pegs that fit into the notches on the tractor fittings. Tilt the tractor back so that the rear notches fit over the rear pegs. Then tilt the unit forward until it clicks into place. That’s all there is to it.
