 The lubricant bar has a PM replacement interval of 600k. At
this time, the lubricant bar and roller should both be
replaced.
 If the machine continues to be used without drum
lubrication, the drum will begin to wear out. So, the
following back-up measures are implemented in case a
technician cannot replace the lubricant at the required
time.
 At 600k, the machine can still be used, but a drum rotation
counter begins.
 When either of the lubricant end sensors is triggered, a
"Near End" alert message is displayed. The machine can
still be used.
 After another 10 km (A4 LEF, about 25 kP), a message on
the operation panel alerts the operator that the lubricant
bar is nearly gone. But the machine can still be used.
 At 40 km (A4 LEF, about 100 kP) after the near-end alert,
the machine stops. The lubricant bar must be replaced.
