Specifications

18. After completing the Power ON Self Test, refer to the Printhead Resistance

value (noted in Step 11 above) and perform the Printhead Voltage

Adjustment on pages 5-12 through 5-14.

19. After adjusting the printhead voltage, activate the PAUSE Key Self Test by

pressing the PAUSE Key while turning the printer power on. Check print

quality.

20. The printer should be ready for operation. If problems arise, refer to

Troubleshooting.

Printhead Adjustments

Print Quality Adjustments

There are five interrelated adjustments that lead to optimum print quality with

increased Printhead life:

• Printhead Parallelism

• Wear Plate (Balance) Position

• Printhead Position

• Printhead Pressure

• Strip Plate Positioning

To achieve optimum print quality, install full-width media and ribbon in the

printer while making the Printhead Adjustments.

1. Prior to performing Printhead Adjustments, activate the PAUSE Key Self

Test by pressing the PAUSE Key while turning the printer power ON.

2. Adjust the Toggle Spring(s) by turning the Knurled Adjusting Nut(s) so that

there is approximately 30 mm (1.2 inches) between the bottom of the

Knurled Adjusting Nut and the top of the black Toggle Button (refer to

Figure 5.3). Be sure the toggle is centered over the media (105S/105Se).

For the 160S, position both toggles so that they are half the distance

between the Printhead Attaching Screw and the outside edges of the

Printhead.

NOTES: The order in which the adjustments are performed depends on the print

quality of the labels printed during the PAUSE Test (see “Sample Labels” in

Troubleshooting).

The first two Printhead Adjustments (Parallelism and Wear Plate) must be

completed prior to attempting to locate the optimum print position. As with the

other adjustments, Parallelism and Wear Plate adjustments are interrelated.

Adjusting one may have an effect on the position of the other.

Excessive printhead pressure will lead to increased printhead wear and

decreased printhead life.

Increased printhead life is possible by combining minimum toggle pressure and

optimum printhead position over the Platen Roller.
