NOTE: If print quality has not improved, try cleaning the printhead with the Save-a-Printhead cleaning film. This specially coated material removes contamina- tion buildup without damaging the printhead. Call your authorized Zebra distributor to order the Save-a-Printhead cleaning kit for the 170PAX2 printer (part # 38902M).

Toggle Positioning

Proper Toggle positioning is important for proper print quality. The toggles should be positioned 1/4 of the width in from the media edges (see Figure 15 inset).

To position the toggles, loosen the set screws (T) with a 1.5 mm Allen wrench and slide them to the desired position on the toggle pivot shaft (U); then, tighten the set screws ½ turn past contact.

NOTE: Perform the Printhead Pressure Adjustment which follows, and make sure the toggle pressure is even, otherwise the media may drift or the ribbon may wrinkle.

Printhead Pressure Adjustment

If printing is too light, or if thick or thin media is used, printhead pressure may need to be adjusted. During this adjustment procedure, refer to Figure 15. (Use the lowest pressure possible that provides the desired print quality.)

1.Refer to the Configuration process starting on page 11 and lower the darkness setting (burn duration) to a value of “2” or “3”.

2.Refer to the PAUSE Key Self Test on page 43 and print test labels at 2” (50.8 mm) per second.

3.Loosen the locking nuts (R) on the threaded shafts of both toggle assemblies.
