Monochrome paper print density
This function makes it possible to adjust the energy level of the printhead to darken the printout or adjust for paper
variations. An adjustment should only be made when necessary. The factory setting is 100%.
Warning: Choose an energy level no higher than necessary to achieve a dark printout.Failure to observe this rule may
result in a printer service call or voiding of the printer warranty. Running at a higher energy level will reduce
the printhead life. Consult your TPG representative or TPG technical support if you have any questions.
When the printer prints high-density print lines (text or graphics), it automatically slows down.

To change the print density:

1 Enter the configuration menu (follow directions on page 21).
2 Select “Set Hardware Options” from the main menu.
Printer responds, “Hardware Options Menu,” and when scrolled prompts, “Set Print Density?”
3 Select “Yes”.
A warning is printed, followed by the density adjustment selections.
Enter clicks for selection, then hold button down at least 1 second to validate.
