The PTR [9] has the function to deliver the paper from the paper transfer timing roller [7].
Since the paper transport speed is controlled by the PTR, if the PTR rotation speed is slower than the target the image will shrink, if faster the target the image will stretch.
Since the paper is simultaneously gripped by the PTR and the paper transfer timing roller, uneven density and banding problems may occur, if the speed differs between these rollers. PTR rotation speed (and paper transfer timing roller speed) is made adjustable for this reason.
