This chapter explains how to optimize and maintain print quality, use printer memory
more efficiently, and maximize throughput.
Optimizing and Maintaining Print Quality
Intermec designed and configured your printer to provide the best possible
print quality for both direct thermal and thermal transfer media. The 4420 and
4440 printers use Precision Print technology to perform high registration
printing, which means that the printer can control the placement of the label
image as it prints. Precision Print technology tracks the media through the
media path and automatically makes adjustments to keep the label image
printing in the same horizontal position from the leading edge of each label.
You can also manually adjust the printer to perform registration tasks such as
correcting uneven print quality.
The following sections contain information on:
•
Correcting uneven print quality
•
Adjusting the print darkness
•
Fine-tuning the top of form position
•
Adjusting the label gap sensor
•
Adjusting the label mark sensor
•
Using the printer memory efficiently
•
Increasing throughput
Correcting Uneven Print Quality
You may experience problems in print quality (ribbon wrinkling or light print
on one side of your label) if the printhead is not making even contact with the
label stock. This condition can happen with any size label stock, but is most
common when using narrow label stock. You need a straight-slot screwdriver
to turn the bias adjust screw.
To achieve the best print quality, adjust the bias adjust screw each time you use
media of a different width.
Note: You must properly adjust the bias adjust screw to prevent premature printhead
failure and excessive platen wear.
