4.2.1 Printhead Alignment Procedure

Depending on the degree of alignment necessary to your Printhead, one or perhaps all of the steps mentioned below may need to be completed.

1. Label Stock Tracking Adjustment

It is critical that the stock feeds straight. This adjustment must be done with a full roll of 4" (102mm) or 4.25" (108mm) wide stock. Complete the following steps:

a.Rotate the Media Guide down and install the stock, keep the Media Guide in the ‘down’ position.

b.Use the Feed Button to feed the labels until the stock begins to track at a stable position.

c.Rotate the Media Guide to the ‘up’ position and slide the Media Guide in or out until the inside edge of the stock is gently resting against the inner Media Guide.

2. Ribbon Feed and Tracking Adjustments

Complete the following steps to complete the Ribbon Feed and Tracking Adjustment.

Turn the Power Switch to the ‘on’ position and use full width paper and ribbon for this adjustment. Install a Thermal-Transfer Ribbon/ Media in the Printer and secure the ribbon to the Ribbon Take-up Hub in a counter-clockwise direction (see Section 1, Figure 1-7).

a.Press the Feed Button several times to normalize the feeding of the ribbon and media. Check for any rippling or bagging of the ribbon as it travels from the Ribbon Supply Hub and goes under the Printhead assembly. If rippling or bagging occurs, follow the procedures outlined in steps b through e.
