1-5. Paper Suction Action

This action applies suction to paper in the printing section.
Because there is only a head gap of about 1.5 mm, paper that lifts up as it is transferred may damage the head.
Suction is required when paper is transferred under the head. Additionally, because suction is difficult to apply if the
edges of a sheet are bent, there is a detector built into the paper path to the printing section to determine if the
paper is not flat. If paper lift is detected, paper transfer is stopped before the sheet reaches the printing section.
(For more information about paper lift detection, refer to Chapter 6, on the registration section.)
