2.5.5 Print density and density of receipt print lines
This function makes it possible to adjust the energy level of the print head to darken the printout. 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.
Consult your Axiohm technical support specialist if you have any questions.
When printing lines at high dot coverage (text or graphics), the printer automatically slows down to limit
power consumption below power supply setting (60W, 75W, 90W).
To change the Print Density:
a) Enter the Configuration Menu.
b) Select “Set Hardware Options” from Main Menu.
“Hardware Options Menu” is printed on the receipt and the question “Set Print Density?” asked.
c) Answer YES (Long click).
A warning is printed, followed by:
Print Density
80% 1 Click
90% 2 Clicks
100% 3 Clicks
110% 4 Clicks
120% 5 Clicks
Enter code, then hold Button DOWN at least 1 second to validate.
2.5.6 Printing duty cycle (printing solid blocks)
In order to guarantee the lifetime of the printer and meet safety standards, receipt printing should not
exceed a 40 % of the duty cycle (for example 2 sec print, 3 sec pause)
