Push Tractor Method
I When
the push tractor is selected, the SPUR GEAR, 16 engages the SPUR GEAR, 17 (Tractor gear) on
the TRACTOR ASSY. COMBINATION GEAR, 8.5, 30 is driven by the paper-feed gear, which in turn is
driven by the paper-feed motor pinion gear. The paper-feed pinion gear, when turning in the direction
of the black arrow, results in pushing the paper through the mechanism.
I During tractor feeding, the LEVER, G, ADJUST is set to the tractor position to disengage the friction
drive. This releases the pressure between the paper advance roller and the platen. Figure 2-5 illustrates
push tractor operation.
