Figure 2

4. Remove the upper shutter spring (small one) and the hopper spring (Fig. 1).

5. Remove the two pins holding the waste bin in place (Fig. 1): first remove the

screw that holds the drum axle in place, then the drum axle itself. To do this,

you must hold the upper shutterbar flat to get the axle out, then remove the large

pin holding the hopper in place.

6. Rotate the cartridge to the other end and remove the two pins holding the

waste bin in place and the one pin holding the hopper in place (Fig. 2).

7. Remove the waste bin from the cartridge shell (Fig. 3). Lift the waste bin by

Figure 3

the right side using a flat head screwdriver and jockey it out by lifting up and

to the right. Clean the waste bin:

a. Remove the cleaning blade (2 screws). Clean, inspect, and lubricate

the cleaning blade. Replace if necessary.

b. Dump the waste bin toner. Use a vacuum to remove any remaining

toner dust. Note: Be careful not to bend, crimp, tear or damage the

clear plastic strip (collection/scavenger blade).

c. Install the cleaning blade.

8. Remove the OPC drum (Fig. 4). Move the drum cover towards you to expose

the drum and slide the drum to the left and lift out. Clean, inspect, and

lubricate the drum and store in a dark place. Replace if necessary, if replace-

ment is required, then perform the following to remove the OEM gears:

a. Grasp the large gear and wiggle it off of the shaft.

b. Drill a hole in the end of the metal plug (where the gear was) large

enough for a 1/4 metal dowel to fit through.

c. Slide the metal dowel into the hole and up until it contacts the edge

of the drum plug.

d. Rap the rod down onto a hard surface to pop the plug out.

e. Install the gear and plug onto the new drum.

9. Remove the toner hopper from the cartridge shell (Fig. 5). Clean the hopper of

all old toner.

screws), insert the gapping strip between the magnetic roller and

doctor blade

and tighten the doctor blade (2 screws).

d. Recheck the gap to make sure nothing shifted during tightening.

e. Insert a toner hoper seal.

f. Fill the toner hopper with toner. Insert toner hopper plug.

10. Remove and clean the corona assembly. Remove the corona assembly by

removing its screw (Fig. 2). Pry the corona assembly to the left and lift it out.

There are two industry methods of cleaning this assembly, manual and ultra-

sonic. The manual method requires using a Scotchbrite® pad. Use a small

piece of the pad and gently move the pad up and down the length of the wire.

The ultrasonic method requires placing the entire corona assembly in an ultra-

sonic cleaner. Note: After removing the corona assembly two or three times,

you need to insure that the contact plate teeth for the corona assembly screw

(Fig. 6) have not been spread too far.

11. Clean the shell of the cartridge to remove any toner dust.

12. Install the toner hopper into the cartridge shell (2 plastic pins).

13. Install the OPC drum.

14. Install the toner waste bin (4 plastic pins).

15. Install the smaller spring on the steel shutter and attach the larger toner hop-

18. Install the color wheel. Note: Make sure to reset the color wheel. Remove

color wheel cover (4 clasps). Lift the gear adjacent to the color wheel, and turn

the color wheel clockwise. Install the adjacent gear and replace cover.
