System Overview
3.3.3.6 Temperature in the Stand-By mode
At the stand-by mode, the engine controls the temperature of the fixing unit for maintaining a specified temperature
for reducing printing time of the first page.
Moreover, the temperature depends on an environment condition. For example, normally the temperature in low
temperature and low marshy place is maintained higher than that in normal temperature and normal marshy place.
3.3.3.7 Temperature in the Warm-Up mode
When the engine operates the warm-up processing, it controls the temperature of the fixing unit for raising the
temperature to the stand-by temperature.
3.3.3.8 Environmental Index
The engine checks the present environment when it performs the printing job or the warm-up process and then
with the checked result, the temperature of fixing unit is assigned with a different temperature for each mode.
It is very important to control the temperature of the fixing unit in the printing process and there are many require-
ments for it. Therefore, a Temperature Table is defined and given by the fixing unit team. See the attachment.
