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.
