(Note) The nip width should be measured both on the operation
and non operation sides after transferring it onto a sheet of
paper. Adjust so that both sides nip widths are the same
and equal the standard value.
(Note) When adjusting the pressure between the water form roller and water oscillating roller, the pressure with
the plate will change. (However even when adjusting the pressure with the plate, the pressure with the
water oscillating roller will not change.) Therefore adjust the pressure with the water oscillating roller
first, and after that, adjust the pressure with the plate.
