If the alignment screw is a large screw

First, using the 4mm Allen wrench, turn the large screw clock- wise a small amount, no more than a 1/4 turn. (Figure 19a)

Now, with the 2.5mm Allen wrench turn the two adjacent small screws (Figure 19b) counterclockwise no more than 1/4 turn.

Locate the small screw that is 180° opposite the first screw (Figure 19c) and turn it clockwise no more than 1/4 turn.

Turn the two large screws adjacent to the small screw (Figure 19d) counterclockwise no more than 1/4 turn.

Repeat the above steps until the front opening is centered in the direction you wanted it to go. You may need to repeat this (or the small screw adjustment process) with other screws in order to align it in other directions.
