Changing the Oil Belt

Attention!

You may leave printer power on while you perform this task, but the printer should not be printing.

This is an image that illustrates how to change the oil belt

Do this task when you see the following message: CHANGE OILER BELT 0793

Note:
You do not have to replace the oil belt the first time you see the CHANGE OILER BELT message. To bypass the message, SELECT the Ready push-button on the main Display/Touch Screen. The message reappears each time end-of-forms is reached or every 4 000 feet of forms thereafter. When 10 000 additional feet of forms have been processed since the message originally appeared, you must change the oil belt before you can return the printer to Ready status.

You need the following items when you change the oil belt:

    Operator Tip

    The oil-belt roll with the unused belt material is the upper roll. The end of the roll with the tab in the core is the right side (nearest the printer).

    Important

    When you install the oil-belt rolls, you must line up the tab in the roll with a slot on the sprocket. If you do not do this, the oil belt does not advance correctly. This causes reduced print quality.

  14. While you hold the upper roll with the unused oil belt against the lower roll, do the following:
    1. Place the right end of the upper roll on the sprocket, lining up the tab in the roll to a slot on the sprocket. Press the upper roll to the right, against the spring.
    2. Place the left end of the upper roll on the sprocket, and let the right spring-loaded sprocket hold the roll in place.

    Note:
    The oil belt must be under the tab (1).
  16. Rotate the upper oil-belt roll to remove slack in the belt.
  17. If you are changing the oil belt and you removed the oil pan that is shown above in step 6, reinstall the pan now.
  18. Raise the hot roll shield.
  19. Close the oil-belt gate.
  20. Turn the wing nut clockwise to latch the gate. Ensure that the gate is firmly latched.
  21. Close the stacker end cover.
