CLEANING AND MAINTENANCE

4.1 INTRODUCTION

This section provides information on user maintenance for the XL Series printers. The
following information is covered here:
• Adjusting the Print Quality
• Cleaning the Print Head, Platen and Rollers

4.2 PROCEDURES

Adjusting the Print Quality
Print quality on the XL printers can be adjusted in two different ways: print darkness and speed.
When adjusting the printer for optimum print quality, a bar code verifier system should be used.
The human eye is a poor judge of the relative widths of the bars in a symbol, a characteristic that
is extremely important for good bar code quality.
4.2.1 Darkness (Print)
This adjustment allows the user to control (within a specified range) the amount of power applied
to the individual print head heat elements. It is important to find a proper print darkness level
based on your particular label and ribbon combination. The printed images should not be too light
nor should the ink from the ribbon "bleed." The edges of each image should be crisp and well
defined.
LCD Panel - The Print Darkness can be set using the front panel LCD panel (see page 3-8) or by
downloading the setting using the Print Darkness software command (see page 5-49). There are
three ranges, 1 (Low), 2 (Medium) and 3 (High). Once the range has been selected, the
Darkness Potentiometer on the Control panel can be used to make finer adjustments.
Darkness Potentiometer - The fine adjustment for Print Darkness is the Darkness
Potentiometer on the operator panel. It provides a continuous range of adjustment, allowing you
to make precise changes. Use a small cross-point screwdriver, turning clockwise for darker print
and counterclockwise for lighter print. See Section 3: Configuration for instructions on performing
potentiometer adjustments.
Note
The PRINT potentiometer adjustment will affect the darkness in all of the command code speed
ranges, i.e. if the PRINT potentiometer is adjusted for lighter print, the darkness will be lighter in
all speed ranges selected by the command code.
