# Description
4 Sensor (MPF/pass‑through)

Aligner section

After the paper reaches the sensor (input), or the sensor (MPF/pass‑through), a count is started. The paper is
pushed up against the aligner rollers to align the leading edge of the paper and form a bubble. After a
predetermined count from the sensor (input) is reached, the motor (aligner) turns and moves the paper through
the aligner rollers and the sensor (input). The sensor (input) detects the leading edge of the paper and
determines the timing from the aligner rollers to the second transfer area, ensuring the proper placement of
the image on the paper. Depending on the position of the paper in the paper path, it is fed faster or slower to
ensure that the paper and image are properly aligned. The image is then transferred from the belt to the right
position on the paper in the second transfer area.
