Lexmark T-Series 500-Sheet Tray Teardown

This procedure gets you access to the electronics and the pinch roller drive/tensioning mechanism.

1) Upper Front Paper Guide
- One M3.5x8mm pan head threading screw.

2) Light-Coloured Upper Front Face (T64X Only)
- Four M3.5x8mm pan head threading screws from underneath.

3) Autocompensator Assembly
- NOTE the relationship of the paper out sensor flag to the actuating stud on the arm of the autocompensator. The stud goes under the curved ramp on the flag.
- Two cable connections.
- Three M3.5x8mm pan head threading screws.
- Unhook the retraction spring.
- Lift the item away.

4) Paper Out Sensor Flag
- Rotate it back a bit and it can be lifted out.

5) Electronics/Mechanism Box
- Two M3.5x8mm pan head threading screws at upper front and rear (not present on later units).
- Four M3x15mm pan head screws w/captive washer (T10 Torx recess).
- Two M3 nut plates.
- NOTE: At reassembly, don't bother putting back the two lower screws -- they're just a needless nuisance.
- Pass-Through Sensor -- dismount it and free its cable from its restraint slot.
- Two claws -- one high up in front; one low at the rear. The front one is easily accessible. Free the rear one by inserting a 1/4" slot screwdriver and rolling it to push the claw forward.
- The box is now free to be lifted out.
