False Drum Lubricant Near-end Alert

A jammed feeler can cause the machine to issue a false drum lubricant near-end alert.

Cause

The feeler that detects lubricant near-end is stuck and caused the system to constantly issue a false drum lubricant near-end alert. This can be caused by removing the drum lubricant components in the incorrect order. Removing the brush roller before the lubricant bar can cause the lubricant bar to pop up and lock the feeler.

Solution

1. Confirm that the setting of SP3-810-021 is not “0: Normal” (because the system is notifying a near-end status).
2. Remove the lubricant blade with the bracket attached and the two lubricant near-end sensors.
3. Place the bracket bottom-side-up on a table and check if the feeler is visible [A]. The feeler is not visible [B] if it is stuck out of position.
   
   If the feeler is stuck, correct its position.
   
   • The feeler is up at [A]. This is the wrong position because the contact causes the near-end alert.
   • The feeler is down at [B]. This is the correct position because there is no contact.
   
4. Reassemble the unit and confirm that the setting of SP3-810-021 is “0”. If the value is “1” or “2”, repeat step 2.

Clear PM Counters

1. Turn the machine off.
2. Open the front doors.
3. Turn the machine on with the front doors open.
4. Enter the SP mode, open SP4622-008, and then reset the counter for the lubricant bar.
5. Close the front doors. This resets the counter.
6. Open SP3810-021 and confirm that the value is ”0”.
7. Exit the SP mode.
