CHAPTER 8: PRINT DRUM SECTION
< Precautions in Reassembly >
(1) On the outskirts of the tail end of the drum body, close to the drum flanges are marked with arrow marks
and F & R imprints. The F imprint should face the flange-F, and R imprint should face the flange-R. With
the drum body in this direction, hook the potbelly shaped holes of the drum body onto the two loosened
existing screws on the drum flanges F and R.
(2) Tentatively place one screw each on the screw holes which the arrow marks point to.

(3) Hook the screen jigs into the holes on the drum body located at the inner edge of the top of the drum
body, and hook the loop ends of the jig on the pillars on the drum flanges F and R.
(4) Push the flange-F and flange-R tightly against the drum body, and tighten the two screws at the arrow
mark which was previously tentatively mounted.
(5) Likewise, push the flange-F and flange-R tightly against the drum body and tighten the two loose screws
at the potbelly holes of the drum body, and then mount and tighten all the remaining screws around the
drum body while pushing the flanges tightly against the drum body.
