PRINT HEAD ALIGNMENT

Print head position has a direct impact on print quality. The print head must be parallel with the platen roller for the printed image to be consistent across the label.

1Open the right housing cover to access print assembly (1, Figure 6-5a).

2 Ensure print head (2) is latched (3).

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.

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.

5Determine which end of alignment plate (4) should be adjusted and loosen its relative set screw (5) or (6).

6Adjust alignment plate (4) then retighten relative set screw (5, 6) while maintaining plate position.

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.

7Test print a label to determine if print head (2, Figure 6-5a) is properly aligned.

8Repeat this procedure until proper alignment is achieved.
