Abstract
In one example in accordance with the present disclosure, a sheet transport device is described. The sheet transport device includes a pickup roller to insert a sheet into a sheet path. A pair of separation rollers of the sheet transportation device form a nip that advances the sheet along the sheet path. A first separation shaft on which a first separation roller is disposed rotates in a first direction as the sheet is advanced and a second separation shaft on which a second separation roller is disposed also rotates in the first direction as the sheet is advanced. The second separation roller is driven in a second direction via a torque limiter. A motor rotates the shafts. A one-way clutch is disposed on the second separation shaft to disengage the second separation shaft from the motor when the motor is operating in a reverse mode.
