The interval between sheets of paper in the paper path is determined by the temperature
readings of the thermistors at the center and end of the pressure roller.
This SP sets Step 1 of CPM down mode. If the amount of the difference between the actual
temperature and target temperature falls in the range between this SP and SP1940 012, this
is judged as Step 1.
[0 to 150/50/5]
12 TDiff:Stp2
This SP sets Step 2 of CPM down mode. If the amount of the difference between the actual
temperature and target temperature falls in the range between this SP and SP1940 013, this
is judged as Step 2.
[0 to 150/75/5]
13 TDiff:Stp3
5
This SP sets Step 3 of CPM down mode. If the difference between actual and target temperature
is larger than this SP setting, this is judged as Step 3.
[0 to 150/100/5]
21 PInt:Stp1
When the pressure roller center and end thermistor detect a temperature in the Step 1 range
(SP1940 011), the setting of this SP is activated to set the length of the interval between sheets
in the paper path.
[1.0 to 5.0/1.4/0.1]
The default setting (1.4) is the variable for Step 1 multiplied by the constant set for Step 1 of
the machine:
• G180: 480 mm. The default interval is 672 mm (1.4 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.
22 PInt:Stp2
When the pressure roller center and end thermistor detect a temperature in the Step 2 range
(SP1940 012), the setting of this SP is activated to set the length of the interval between sheets
in the paper path.
[1.0 to 5.0/2.1/0.1]
The default setting (2.1) is the variable for Step 2 multiplied by the constant set for Step 2 of
the machine:
• G180: 480 mm. The default interval is 1008 mm (2.1 x 480 mm).
