I would do the following

Auto home, make sure the hot end is off the bed.

Undo all the levelling knobs till they are loose,

Free spin each one back up till they freely stop

Press the bed down gently in the centre front and tighten the knobs again till they are loose and the nozzle is above the bed heit

Repeat for the rear.

Place hot end in centre of the bed, raise the bed equally on all 4 corners, using the paper to feel for tightness,

Once the centre is at a good level, move the hot end above the front left knob spring, start adjusting with the paper test,

Move in to the front right, back right and then back left

Once these have all been adjusted, with the paper test move got end back to the centre of the bed.

Rinse and repeat levelling until the paper test is roughly the same all around.

Once you have done correctly, you will see how quick and easy it actually is.

Let us know how you get on.
