Cause
If there is a difference in height at the front and at the rear of the Fixing Unit, paper proceeds unevenly when it passes through

If the front side is lower, paper on the front side proceeds less smoothly than the rear side, and the image on the front side shrinks

If the front side is higher, paper on the front side proceeds more smoothly than the rear side, and the image on the front side
enlarges [b].
Execute fixing alignment adjustment so that the height at the front and the height at the rear of the Fixing Unit become the same.
