III. Adjust the printhead position.

1. If the Cutter Module is used, remove it.

Remove the two Phillips head mounting screws that fasten the Tear-Off Plate,

then remove the Tear-Off Plate by pressing it IN then UP to disengage the

mounting bracket.

2. Use a #2 Phillips screwdriver to remove the Printhead Support Bracket and the

two mounting screws.

3. Use a #2 Phillips screwdriver to loosen (do not remove) the two screws holding

the Strip Plate in position.

4. Also use the #2 Phillips screwdriver to loosen (do not remove) the two (2)

Printhead Position Locking Screws two (2) full turns. Then re-tighten

finger-tight to remove looseness.

5. Use the Head Open Lever to push the Printhead and its Mounting Bracket all the

way forward.

6. Prepare to adjust the printhead position. See Figure 5.8. Place a flathead

screwdriver in one of the Printhead Adjustment Slots.

7. Press the PAUSE key to start printing test labels.

8. While applying forward pressure against the printhead with the Head Open

Lever, adjust the Position Adjustment Slots, first one, then the other, until the

darkest printing is observed on the test labels.

9. Insure that the lines printed on the test labels are parallel to the top of the label

by making minor adjustments to the left or right Slot.

10. While still holding the Head Open Lever against the Printhead Bracket, tighten

the two (2) Printhead Position Locking Screws.

11. Re-install the Printhead Support Bracket using the two mounting screws.

12. Press PAUSE and observe the test labels to insure consistent print quality and

proper parallelism across the top of the labels. Repeat procedure if required.

13. Once again, observe the test labels for parallelism and for consistent print

darkness across the complete width of the label.

14. If, after adjusting printhead position, one side of the label is printing lighter than

the other, refer to the Toggle Pressure Adjustment section and slowly increase the

Toggle Pressure on that side until the print darkness is balanced.

15. Press the PAUSE key to stop printing. Reinstall the Tear-Off Plate and press the

PAUSE key again to continue printing test labels.

16. While observing the print darkness, repeatedly press the UP (FEED) key to make

the printing DARKER until the optimum darkness is achieved.

NOTE: If the optimum print darkness cannot be achieved through the darkness

adjustment, it may be necessary to increase the Printhead Toggle Pressure.

To extend the life of your printhead, use the lowest Toggle Pressure that produces the

desired print quality. Increasing Toggle Pressure to improve print quality is only

recommended when the continued increase of print darkness does not provide

satisfactory results.

17. While labels continue to print, position the Ribbon Strip Plate so the ribbon

remains flat and smooth and tracks properly across the Ribbon Guide onto the

Ribbon Takeup Spindle.
