Changing the oiler belt

Figure 107. Oiler belt
Oiler belt

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

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 touchscreen 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.

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

CAUTION:
<70> The oiler belt, oiler wick roll, and their environments are high temperature areas. Be very careful when working in these areas.
  1. Open the stacker end cover.
    Note:
    When the oiler-belt gate is opened, the fuser begins to cool down immediately, and the printer operator panel message changes to OILER GATE OPEN.
  2. Turn the wing nut counterclockwise to release the oiler-belt gate.
  3. Place several layers of absorbent material, such as paper towels, on the floor beneath the oiler-belt gate.
  4. Open the oiler-belt gate. Ensure that the gate is securely latched in the open position.
  5. Allow the printer to cool for at least 30 minutes.
  6. Lower the hot roll shield.
  7. If you are changing the oiler belt and the oil pan shown above is present, do the following. Otherwise, go to step 8.
    1. Remove the oil pan. To do this, lift the pan until the hooked portion is disengaged from the lower oiler belt support shaft.
    2. Check to see if the absorbent pad is saturated with oil. If the pad is saturated, continue with the next step. If it is not saturated, go to step 8.
    3. Remove the new absorbent pad (part number 30H6594) from the plastic shipping bag.
    4. Remove the saturated absorbent pad from the oil pan.
    5. Place the saturated pad in the plastic shipping bag and discard the bag in an approved waste container.
    6. Install the new absorbent pad in the oil pan.
  8. Grasp both ends of the upper oiler-belt roll, and move it to the right, against the spring.
  9. Pull out the upper oiler-belt roll, left end first.
  10. Roll the upper roll down against the lower roll.
  11. Holding both rolls, press the lower oiler-belt roll to the right, against the spring.
  12. Remove the lower oiler-belt roll, left end first.
  13. Place the old oiler belt on several thicknesses of absorbent material, such as paper towels.
  14. Remove the new oiler belt from its carton, and save the plastic bag for the old oiler belt.
    Operator 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.

  15. 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.
  16. Working with the lower roll, repeat step 15.
  17. Rotate the upper oiler-belt roll to remove slack in the belt.
  18. If you are changing the oiler belt, and you removed the oil pan shown above in step 7, reinstall the pan now.
  19. Raise the hot roll shield.
  20. Close the oiler-belt gate.
  21. Turn the wing nut clockwise to latch the gate. Ensure that the gate is firmly latched.
  22. Close the stacker end cover.
  23. The printer operator panel message may change to WARMING UP or PLEASE STAND BY.
  24. To resume processing, select Start on the printer operator panel or the Main touchscreen panel.
    CAUTION:
    <85>For printers with microcode levels, version 11.6.128 and higher, both printers and attached pre and postprocessing equipment can be started from the main panel of the printer console and the printer operator panels. Visually assure that no other personnel are working on the system before starting the system.
  25. Place the old oiler belt inside the plastic bag and discard it.
