Abstract
A transport monitoring control device includes a transport unit configured to transport a recording medium while nipping the recording medium, a driving unit configured to drive the transport unit, a detector configured to detect a waveform related to a load of the driving unit when the recording medium enters the transport unit or is discharged from the transport unit, and a determining unit configured to determine whether the recording medium is skewed with respect to the transport unit, based on a waveform width at a height obtained by multiplying a peak value of the waveform by a predetermined coefficient.
