• Position your thumb on the front end of the corona assembly, and position two fingers in the area where the used OPC drum was
removed from the cartridge frame.
• Using your thumb, gently push the corona assembly rearward until the locating pins release from the cartridge frame. Lift the
front end of the corona assembly out of the cartridge frame. Holding the corona assembly in this position, carefully pull it away
from the white corona pivot at the rear of the cartridge frame. Lift the entire corona assembly out of the cartridge frame.
5. Remove the four screws securing the waste toner compartment lid (F) to the cartridge frame. Using a small flathead screwdriver,
carefully pry the lid from the waste toner compartment. Vacuum out waste toner.

Rebuilding:
NOTE: All used parts should be inspected and cleaned. Worn or damaged parts should be replaced prior to rebuilding the drum
unit/cartridge.
7. To rebuild the corona assembly:
• Remove the screen grid (H) and the two end block covers (J).
• Remove the two corona wire positioning blocks (K).
• Using true flush side cutters (Snap-on
secure the corona wire to the front and rear end blocks. Discard the used press fit pins and used corona wire.
• Using one corona wire anchor screw (three are provided in the Katun rebuilding kit, including one spare screw), secure the
corona wire spring (L) to the rear end block. Using a #0 Phillips screwdriver, insert and partially tighten a second screw in the
front end block. NOTE: DO NOT yet tighten this screw securely.
• Attach the looped end of the precut corona wire to the spring. Firmly pull on the wire and wrap it around the partially tightened
screw in the front end block. Tighten this screw until proper wire tension is achieved. IMPORTANT: Make certain that the spring
in the rear end block does not extend past the guide for the corona wire positioning blocks.
• Cut off excess corona wire as close as possible to the screw in the front end block. Carefully clean the new Katun corona wire
with isopropyl alcohol to remove any contaminants left by handling.

properly distribute Kynar powder and minimize the possibility of "blade flip."
