Oil End Detection and Recovery

If the oil tank at the bottom of the machine has no oil in it, the following occurs:
1) The oil pump operates for 50 milliseconds and waits for 150 milliseconds. If
the oil end condition still exists, this step is repeated. If the sensor still does
not detect oil, this step can be repeated up to 150 times (total maximum time
taken: 30 seconds).
2) If oil is still not detected, the pump stops for 30 seconds.
3) The oil pump repeats steps 1 and 2 until oil is detected. The pump can
repeat these steps up to 9 times. So, the machine can pump for up to 9
minutes if oil is not detected ([30 seconds + 30 seconds] x 9).
4) If oil is still not detected, the oil end counter starts. This counts the pages fed
through the fusing unit. Every 100 pages, the oil pump operates again for 50
seconds to try to get oil into the fusing unit.
5) When the counter goes up to 50, the operation panel indicates oil near end
(the counter is not reset).
6) When the counter goes up to 500, the code "SC 570" appears on the display,
and printing stops.
7) To clear the oil end condition, a technician adds some oil to the oil tank in
the bottom of the machine and clears the SC code (this is a Level A code).
Then, the oil pump resumes steps 1 through 3.
NOTE: Do not switch the machine on with the fusing unit out of the machine
if an oil end condition exists. This will clear the oil end counter, and
the machine incorrectly detects oil.
8) If the oil end condition is cleared, the procedure ends. If not, the code "SC
570" appears again.
