Lexmark T430 Fuser Replacement

You'll want to keep the toner cartridge access door closed while you're inserting a fuser. There's a linkage in the machine between the door and and a crank rod on the fuser. With the door closed, the linkage is sure to re-engage correctly when you put a fuser in.

Some of the screws involved are in fairly deep wells; you have to look for them.

1) Cartridge


2) Tray 1

3) Top Cover -- Loosen its Rear End
- Two M3x10mm washerhead threading screws; the two highest screws at the rear. (They're in deep wells.)

3) Left Side Cover
- Two finger-operable claws at the front.
- Swing the cover out enough that you can move it rearward to unhook it at the back.

4) Right Side Cover
- One M3x10mm washerhead threading screw under the toner cartridge access door.
- One M3x10mm washerhead threading screw in a deep well at the upper rear.
- One claw at the front by the tray 1 opening.

5) Rear Cover/Door Assembly
- One in-line cable connection at the left side, lower rear.
- Three M3x10mm washerhead threading screws.
- NOTE that one of the screws is very low down by the tray 1 cavity at the right.

6) Fuser
- Toner cartridge access door closed.
- AC power cable -- unplug it and free it from its hook-restraint.
- Exit sensor cable (three-conductor).
- Thermistor cable (two-conductor).
- Four M3x10mm washerhead threading screws -- two are high up and easily seen; the two lower ones are quite far forward inside the machine.
- Pull the fuser out the rear of the machine.
