This will probably work for other laser printers as well though the details
may vary. Use at your own risk!

If your Sharp JX-9460 laser printer has decided it is time to give you
the "REPL.DRUM" message on the LCD screen, but the print quality is
still fine, then all you need to do is fool the page counter to think a
new drum has been put in. Here's how:
- Open the cover and remove the photo-drum.
- Look down into the area under where the drum was. On the right hand
side, you will see two circular metal contacts. You will also see two
"slots" on the far right side. These slots mesh with plastic tabs on the
- At this point you will need two paper clips. Use the first one (unbent) to
insert into the FORWARD-MOST slot. You don't have to push it very far. You
will hear a click and the LCD panel will probably go from saying "COVER
OPEN" to saying "REPL.DRUM." Keep holding the paper clip in the slot while
- Touch the 2 ends of another paper clip BRIEFLY to the two circular metal
contacts. (you will have to unbend the paper clip a little.) It will spark
a little. Don't worry, it is only 4 volts. But I wouldn't hold it there
for too long.
Anyway, the theory behind this is that the new cartridge comes with a fuse in
it which is blown by the 4 volts the first time you insert the cartridge.
That is what resets the counter. Better than spending $190 on a new drum,
