5.10 Print Density (Menu Option)
In service mode the density of the printing on the thermal paper can be
adjusted. There are 13 density settings (0 to 12) to choose from on all
machines, the default being 7. Both print heads, Rohm and Axiohm, have their
recommended print density settings printed on them in the form of head
resistance (Ohms) and resistance class respectively, which have to be
converted to density settings (see Tables 5.1 and 5.2).
NOTE: The following recommended print density settings must only be used
as a guide.
