    -or-
    For A3 paper, watch the scale above the front exit roller.

    • If you see the edge of the paper at the center mark on the scale, the paper is aligned correctly.
    • If you see the edge of the paper at any mark to the right of center, the paper is shifting toward the front of the machine.
    • If you see the paper at a mark to the left of center, the paper is shifting toward the rear of the machine.
  4. If side-to-side registration is still shifting to either the rear or front of the machine, correct it. (Skew and Side-to-Side Registration)
  5. Print out some sheets with center-folding and make sure that the sheets are folded evenly into equal halves.
  6. If the center folding is not aligned, correct it. (Booklet Finisher Center Fold Correction)
