[1] With the parameter SYSTEM PARAMETERS > Temp. reduction activated, the driving power of the printhead
– and therefore indirectly the print contrast – are reduced. Reduction starts at a temperature of 26°C.
The maximum value is maintained at 54°C and above.
Readout example The driving power of the printhead is 100% (setable in online mode after press-
ing the Prog button).
The printing layout contains a lot of black areas. For this reason, the temper-
ature reduction is activated with 40%.
« SYSTEM PARAMETERS > Temp. reduction = 40%.
Now, if the printhead temperature rises above 26°C, the driving power will be
reduced automatically.
Reading out the diagram results in: With a given printhead temperature of ap-
prox. 40°C, the driving power is reduced to approx. 80%; with a supposed
printhead temperature of 54°C or above, it is reduced to 60%.
