Unacceptable Print Patterns

If the gap between the print pad and the print jet nozzles is too small, the

Print Pad Level calibration lines will press in and scrape the baseline. If

all four corner calibration points appear like the pressed prole illustration

(A), turn the three (3) print pad adjuster knobs clockwise (right) 1-step to

increase the gap. Reprint the Print Pad Level calibration print again.

If there is a gap between the Print Pad Level calibration lines and the

baselines like the illustration (B), turn the three (3) print pad adjuster knobs

counter-clockwise (left) 1-step to decrease the gap. Reprint the Level Gap

calibration print.

NOTE: Once all four corner Print Pad Level calibration points are correct, verify the Z-Gap to ensure that it is still correct.

Reading The Z-Gap Calibration Print

Adjusting the Z-Gap

The Z-Gap should be within specications before adjusting the Level Gap. If

adjustments to the Z-Gap are necessary, perform the adjustments and then

print the calibration le again to verify the correct Z-Gap. A correct Z-Gap is

indicated when there is no gap in the Closed Z-Gap measurement and there

is a gap in the Open Z-Gap measurement.

NOTE: The Closed Z-Gap (A) and the Open Z-Gap (B) are two

different measurements but should be read together.

Correct Closed Z-Gap

Referring to the illustration, the Closed Z-Gap bars (B) should touch the

baseline (A).
