T/H energy control
2-43
The default is 7%. This means that during normal printing mode, the thermal
head energy is 93% of the maximum possible (100 – 7).
T/H energy control - eco
The default is 10%. This means that in economy printing mode, the thermal
2-44
head energy is reduced by another 10%. With the default settings, this means
that the thermal head energy is 83% of maximum power (100-7-10).
T/H control by temp: A4
2-45
Set the ink temperature correction in the A4 drum.
OFF: Temperature inside the drum takes a constant value irrespective.
T/H energy control: A4 drum
2-46
Initial value is 12%.In this case, that means thermal head energy can be up to
88% in printing mode (100-12=88%).
T/H energy control: A4 eco
Initial value is 15%.In this case, in economy printing mode (A4) means that an
2-47
additional 15% reduction will be thermal head energy. Thermal head energy in
78% maximum. (100-7-15=78%)
