17. Apply gentle forward pressure with the Head Open Lever against the Printhead Assembly and

adjust the Position Adjustment Screws clockwise, until the darkest printing is observed on the test

labels.

18. Insure the printed lines are parallel to the top of the test labels, by making minor adjustments to

the left or right screw then press the PAUSE Key to stop printing.

19.

While still applying pressure with the Head Open Lever, tighten the two (2) Printhead Position

Locking Screws at the rear of the Printhead Assembly.

20. Install the Printhead Support Bracket over the Outboard Platen Bearing and install the two

mounting screws.

21. Press the PAUSE Key and observe the test labels for consistent print quality and proper parallelism

across the top of the labels. Repeat steps 13 through 21 if necessary.

22. Remove the adjustment screws and return them to their storage position. Once again, observe the

test labels for parallelism and consistent print quality.

23. If, after adjusting printhead position, one side of the label is printing lighter than the other, refer to the

Toggle Pressure Adjustment information on the following page and slowly increase the Toggle Pressure

on that side until the print darkness is balanced.

24. Observe the print darkness, and repeatedly press the UP (FEED) Key to make the printing

DARKER, until optimum darkness is achieved.

25. NOTE: If the optimum print darkness can not be achieved through the darkness adjustment, it may be

necessary to increase the Printhead Toggle Pressure. However, adjusting the Toggle Pressure to

increase the print darkness is a very last resort.

The Printhead life can be extended by using the lowest Toggle Pressure that produces the desired print

quality. Do not increase overall head pressure to increase darkness unless the continued increase of Print

Darkness does not provide satisfactory results.

26. While labels continue to print, position the Ribbon Strip Plate so the ribbon remains flat and

smooth while moving and tracks properly across the Ribbon Guide onto the Ribbon Take-Up

Spindle.

27. Tighten the two Strip Plate mounting screws and print 40 to 50 labels to insure consistent print

quality.

28. If labels are printing properly, press the PAUSE Key to stop printing.

29. Press the MODE Key three (3) times (all MODE lights OFF) and the Darkness setting will be

saved in Memory.

30. Complete the process by turning the AC Power OFF.

CAUTION: The printer electronics are susceptible to static discharge.

Wear an anti-static wrist strap and attach it to the printer chassis.

1. Turn printer power OFF and use proper static precautions before proceeding.

2. Remove the media and the ribbon if installed.

3. Close and latch the Printhead then use a pencil to outline the wings of the

Head Bracket “C” on the top surface of the Head Mounting Bracket “B”.

See Figure 5.11. These marks will be used to identify the original position

when reinstalling the Head Mounting Bracket “B”.
