Procedure:

Do this procedure when you see the 0793 CHANGE OILER BELT message.

Note:
You do not have to replace the oiler belt the first time you see the CHANGE OILER BELT message. To bypass the message, select Start on the printer operator panel of the Main touch panel. The message reappears each time end-of-forms is reached, or every 4 000 feet of forms thereafter if you are using a roll-feed preprocessing device. When certain additional feet of forms have been processed since the message originally appeared, you must change the oiler belt before you can return the printer to Ready status.
caution statement <70> The oiler belt, oiler wick roll, and their environments are high temperature areas. Be very careful when working in these areas.

  12. Place the old oiler belt on several thicknesses of absorbent material, such as paper towels.
  13. Remove the new oiler belt from its carton, and save the plastic bag for the old oiler belt.
    Tip:
    The oiler-belt roll with the most material is the upper roll. The notched end of the roll is the right side (nearest the printer).
    Important:
    When you install the oiler-belt rolls, you must line up the notches in the rolls with the tabs on the sprocket. If you do not do this, the oiler belt does not advance correctly and causes reduced print quality.
  14. With the upper (larger) roll held against the lower roll, do the following:
    1. Place the right end of the upper roll on the sprocket, lining up the notches in the roll to the tabs on the sprocket. Press the 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.
  15. Working with the lower roll, repeat the previous step.
  16. Rotate the upper oiler-belt roll to remove slack in the belt.
  17. Raise the hot roll shield.
  18. Close the oiler-belt gate.
  19. Turn the wing nut clockwise to latch the gate. Ensure that the gate is firmly latched.
  20. Close the end cover.
  21. The printer operator panel message may change to WARMING UP or PLEASE STAND BY.
