• To restore the standard nip pressure, place
the spring /Fr [2], /Rr [3].
• Removing/placing the spring with the nip
pressure up tends to stretch the spring. Thus,
remove/place the spring with the standard nip
pressure. If tension of the spring /Fr and /Rr
differs, a transfer misalignment occurs. When
restoring the standard nip pressure, in case
the spring was stretched, do not use it and
replace it with a new one.
• In case the spring /Fr [2], /Rr [3] are not easily
removed from the hook hole /Lw [5], remove it
from the hook hole /Up [4] first. Then, while
holding the spring not to drop, twist counter-
clockwise (nip pressure up) the conveyance
roller /T axis [1] and rotate the cam [6] to
make a gap, thus making it easy to remove
the spring.
• Be careful not to drop the spring. Put a paper
over the ADU section [7] so that the spring
does not fall inside the machine.

Twist clockwise the conveyance roller /T axis [1] to
make the nip pressure standard.
(See P.511)
Remove 2 springs /Fr [2], /Rr [3] from the hook
hole /Up [4], /Lw [5]. (By removing the spring, pre-
transfer roller's own weight becomes the only nip
pressure.)
Reinstall the above parts following the removal
steps in reverse.
