Lexmark T63X -- Touchy Cover Interlock

If a machine has a touchy cover interlock giving false 'Close Door or Insert Cartridge Messages', don't try bending the switch's actuating lever to 'adjust' it -- that's asking for trouble. Instead, 'bulk up' the switch's lever with 1/8" diameter heat-shrink tubing. Three 5/16" lengths of Alpha FIT-221 tubing are ideal. It should look like this when you're done installing the tubing lengths.

The third tubing length can just barely be gotten slipped on. Make sure you've fully shrunk the first two tubing lengths, and the third length will go on.
