62 Paper Interval Step 3 II
When the temperature of the hot roller drops during continuous printing, the
machine enters the CPM down mode to increase the distance between sheets of
paper going through the fusing unit. This SP adjusts the size of the interval
between sheets in the paper path after CPM Down Control II has been switched
on with SP1940-51 (Enable 2).
[1 to 10 / 8.5 / 0.1]
Note : The size of the interval is adjusted with either SP1940-16, or SP1940-62.
71 Enable III
[0 to 1 / 0 / 1]
When this SP is set to "1":
ƒ The thermistors at the center and end of the pressure roller measure the
temperatures.
ƒ
The temperature at the center of the pressure roller is subtracted from the
temperature at the end of the pressure roller.
ƒ If the difference is greater than the setting of SP1940-081, the interval
between sheets of translucent paper is calculated by multiplying the normal
length of the paper and the setting for SP1940-091.
CPM down control compares the settings from among these three SP codes and
selects the largest value for the paper interval:
ƒ SP1940-001 I
ƒ SP1940-051 II
ƒ SP1940-071 III
81 Temp Differential: Step 1
[0 to 150 / 30 / 5]
When SP1940-1 is set to "1":
ƒ
The thermistors at the center and end of the pressure roller measure the
temperatures.
ƒ The temperature at the center of the pressure roller is subtracted from the
temperature at the end of the pressure roller.
ƒ If the difference is greater than the setting of SP1940-081, the interval
between sheets of translucent paper is calculated by multiplying the normal
length of the paper and the setting for SP1940-091.
