3. Remove the wiper blade from the waste hopper by unscrewing the two screws

4. Next, lift out the corona wiper assembly (fig. 5). Note that the corona wire

5. To remove the OPC, pry the two spacers off of the metal axle rod (fig 7).

Then grasp the drum axle and gently lift the OPC from the toner hopper
(fig. 8).

a. The OPC contains a full axle rod with a fixed magnet. The magnet aids

in the transfer of toner to the OPC. At the D shaped end of the axle
there is a coder pin. The coder pin and the flat side of the axle hold the
magnet in the correct position for proper toner development (fig. 9).

b. In order to replace the old OPC with a new one (P/N PBDR10) the helical

gear needs to be removed so the magnet can be removed and inserted

into the new OPC.

6. The air gap rollers (P/N PBCP10) act as a replacement for mag roller bushing

(fig. 10). They provide the gap between the OPC and the mag roller and need
to be inspected carefully and replaced if necessary.

Figure 10

The mag roller assembly can be removed with 4 screws. There is a screw on

both ends of the mag housing (fig. 11), and two on the back side of the toner
hopper for a total of 4 screws. This will expose the area where the seal is
installed (fig. 12).

7. To install the seal start by removing the old seal material, clean surface with

alcohol and apply new seal (P/N PBSL40 fig. 13)). Slide the pull tab end of
the seal under the felt covered wedge and replace the wedge.

8. To clean the mag roller remove the toner scraper blade, 2 screws (fig. 14).

Use compressed air to remove excess toner from the mag roller, followed by
a clean cloth saturated with 99% IPA.

9. Do not remove the gear assembly on the side of the cartridge (fig. 15). It is

next to impossible to reassemble.

Figure 15

10. The cartridge can be refilled by removing the hopper plug using a flat head

screwdriver (fig. 16). Fill with toner and replace plug.

11. Reassemble the cartridge in reverse order to insure proper assembly.
