Control panel access on the earlier T models was a breeze. On the T64X it's an awkward chore.
- - -
Proceed as follows:
1) Paper Support
- Tip it up to about a 45 degree angle and tug it off its hinge pins.
2) Control Panel Cover & Window
- Two M2x8mm washerhead screws from in behind (they're No.1 Phillips recess).
- Tug forcefully at the upper rear lip and the cover will come away.
- The window is free to be removed once the cover is off.
3) Toner Cartridge Access Door Cover w/Control Panel
- One M3x10mm washerhead threading screw at the centre.
- Two M3.5x 9mm threading screws w/captive washers at the lower left and right.
- NOTE that the screw at the extreme lower left can remain in place.
- The cover has four 'hooks' near its upper edge that retain it quite securely. Tug the cover's lower edge upward and toward you to free them.
- Two cable connections.[1]
- NOTE the 'hook' arrangement for the cable at the left.
4) Control Panel
- NOTE: If you 'bridge' the Toner Cartridge Access Door Door Cover assembly across an open cardboard carton, the buttons won't get dislodged when you take away the Control Panel.
- Seven M3x8mm washerhead threading screws.
- NOTE that there's a roughly 'central' screw location that isn't used.
- - -
To fully dismantle the door cover for washing or whatever:
1) Latchbar w/Spring
- One M3.5x 9mm threading screw w/captive washer.
2) USB Connection PCA
- One M3x8mm washerhead threading screw.
- One claw.
3) Two Keypad Membranes
4) One Key Array
5) Three Individual Buttons
- NOTE how they're 'keyed' for correct reassembly.
6) One 'Lens'
The five buttons at the centre can remain in place, even for washing.

Note[1] The cable at the right for the USB connection usually has a big ferrite bead on it that can be awkward to deal with when the cover is being reinstalled. Machines without the ferrite bead are probably from early production.
