SP1-917-1 specifies the constant
T
in the
following process:
1. When the main switch is turned on, the
controller checks the temperature of the
pressure roller, and resumes or restarts a
timer (see step 3).
2. When the timer reaches
T
, the controller
checks the temperature of the pressure roller.
•
If the temperature is 60
°
C or higher, the
controller does not execute the machine
temperature corrections to be conducted
under the low temperature conditions (
☛
SP1-912). The controller clears the timer to
zero, then restarts it.
•
If the temperature is less than 60
°
C, the
controller executes the corrections above.
The controller clears the timer to zero, then
restarts it.
•
If the main switch is turned off, the
controller stops the timer, but does not
clear it.
3. When the main switch is turned on, the
controller checks the temperature of the
pressure roller.
•
If the temperature is 60
°
C or higher, the
controller resume the timer (the timer is not
cleared to zero).
•
If the temperature is less than 60
°
C, the
controller clears the timer to zero, then
restarts it.
Summary: At 1 hour after switching on, if the
pressure roller temperature is more than 60
°
C,
then SP 1-912 is not effective.
