Abstract: In some examples, velocity and torque based media motor control may include ascertaining a velocity and torque for a feed roller motor associated with a feed roller, and ascertaining a velocity and torque for a drive roller motor associated with a drive roller that is to receive media from the feed roller. Further, velocity and torque based media motor control may include determining whether the torque for the drive roller motor is greater than a torque target. In response to a determination that the torque for the drive roller motor is greater than the torque target, the torque for the drive roller motor may be reduced to the torque target, and the torque for the drive roller motor may be maintained at the torque target.

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.

Abstract: An apparatus may include a processor that may be caused to access a plurality of measurements of a device. The processor may provide the plurality of measurements as an input to an autoencoder, the autoencoder being trained based on measurements of devices in working condition and access an output of the autoencoder, the output comprising a reconstruction of the input based on decoding an encoded version of the input. The processor may further be caused to determine whether the device will fail based on the output.

Abstract: In some examples, printing device performance analysis may include actuating a motor to operate a first separation tire of a printing device in a first rotary direction. The first separation tire may be operable adjacent to a second separation tire rotatable in a second rotary direction that is opposite to the first rotary direction to separate physical media. Printing device performance analysis may further include actuating the motor to operate the first separation tire in the second rotary direction, and determining whether a motor torque difference of the motor between the first and second rotary directions is greater than a predetermined threshold.
