3 Look downward to print head (2) to locate head alignment plate (4, Figure 6-5b).
4 Ensure the values of alignment scales (A) and (B) are the same.
5 Determine which end of alignment plate (4) should be adjusted and loosen its relative set screw (5) or (6).
6 Adjust alignment plate (4) then retighten relative set screw (5, 6) while maintaining plate position.

NOTE: If the scale values are not the same, this may be the cause of print quality
issues. However, matching scale values does not ensure proper alignement. If the
scales do not match, for this procedure to align the scales, reprint, and then readjust
as deemed necessary.
NOTE: There is a slot at each adjustment scale (A, B) in alignment plate (4) where an
object may be inserted to assist in adjustment. An appropriately sized Standard
screwdriver works best.
