2.4.07 Release Lever Operation

The release lever (on the power switch side of the printer) sets the unit for continuous or cut-sheet
feeding.
Cut-Sheet
The release lever is pushed back (towards the rear of the printer).
When the release lever is set for cut-sheet feeding, the change gear moves out (in the direction of arrow
A). The pin tractor becomes inoperative, because power is not transmitted from the platen gear (through
the idler and change gears) to the tractor gear.
Cut-sheets are fed by the rotation of the platen.
Continuous
The release lever is pushed forward (towards the front of the printer).
When the release lever is set for continuous feeding, the reset spring presses the change gear in (in the
direction of arrow B). The pin tractor operates, because power is transmitted from the platen gear (through
the idler and change gears) to the tractor gear.
Continuous feeding is due to the rotation of the pin feeds, not the rotation of the platen.
