Using the adjustment knobs, align the springs with the sheet. Verify that the springs

Move the front paper guide to the stack, so that the springs press gently against it.
Allow the spring tongues to press against the left edge of the stack so they are
deflected slightly by 2 to 3 mm (0.08 to 0.12 inch).
Using the adjustment knob, adjust the trailing edge guide. Allow the guide to press
gently against the middle of the stack.
On the control panel, click the Consumables menu, and then select Substrate,

The next sheet to be picked up should stay below the sheet separators.
