Transfer Corona Assembly
2) Detach the gut wire from the transfer co-
rona assembly; see p. 4-22.
3) Free about 40 mm from the corona wire
reel (0.06 mm dia.), and form a loop at its
end about 2 mm in diameter.
Note:
Wind the corona wire around a hex key
once, and turn the hex key four to five
times; then, twist it to form a loop.
4) Cut the twisted end of the corona wire to
about 1 mm or less using a nipper.
5) Hook the loop of the corona wire as shown
in Figure 4-811, and lead the wire along the
V-groove of the height adjusting roll.
Hook the corona wire tension spring on
the corona wire, and twist the spring three
to four times as shown.
6) Cut the excess corona wire to about 1 mm
or less using a nipper.
7) Pick the end of the corona wire tension
spring using tweezers, and hook it on the
corona terminal.
Note:
i. Make sure that the corona wire is free
of breaks or twists and its gold plat-
ing has not peeled.
ii. Make sure that the corona wire is not
slack; normal, if the length of the co-
rona wire tension spring is 12 mm.
iii. Make sure that the corona wire is in
the V-groove of the height adjusting
roll.
