Setting a smaller or larger number decreases or increases the length of the interval with this
simple calculation. This standard interval can be modified slightly with SP1923.
23 PInt:Stp3
When the pressure roller center and end thermistor detect a temperature in the Step 3 range
(SP1940 013), the setting of this SP is activated to set the length of the interval between sheets
in the paper path.
[1.0 to 5.0/3.5/0.1]
The default setting (3.5) is the variable for Step 3 multiplied by the constant set for Step 2 of
the machine:
• G180: 480 mm. The default interval is 1680 mm (3.5 x 480 mm).
Setting a smaller or larger number decreases or increases the length of the interval with this
simple calculation. This standard interval can be modified slightly with SP1923.
1941 PreFB:TDiff
This SP sets the temperature differential that determines when the machine adjusts for pressure
roller feedback control when the difference between the temperatures of the center and end of
the pressure roller is greater than 20°C (Default: 20).
[0 to 50/20/5]
Example
If this SP is set to "50": and there is a difference between the temperatures at the center and
end of the pressure roller after more than 50 readings, then pressure roller feedback control
shifts to the supplement mode.
1942 PreFB:THI:NP
This SP sets the interval between temperature samplings for pressure roller feedback control.
