Change Both UV Lamp Bulbs

Introduction

The printer uses two UV lamps, one on each side of the carriage, to cure the UV ink during printing. The bulbs in these UV lamps have a limited lifetime and must be replaced by the operator if they fail or when they can no longer cure the ink at maximum available power.

About this task

Although the expected life of the UV lamp bulbs is 500 hours, there are factors that can reduce that time. Operational practices, such as turning the lamps off and on frequently, using them at high intensity all of the time, or touching the bulbs with your fingers, can shorten their life. Océ recommends that both UV Lamp bulbs be replaced at the same time to ensure that the curing effect is balanced when printing in both directions. In the case of a premature failure or accidental breakage of one lamp, the operator can decide to replace only one lamp but should confirm image consistency after the replacement. Uneven curing can cause gloss banding in the printed image.

NOTE

The Flatbed Settings icon on the printer interface allows the operator to control the power output of each UV lamp independently. To extend lamp life, use the lowest setting that provides adequate curing for a particular media. However, avoid handling media with insufficient curing as partially cured UV ink on your skin can cause irritation and sensitization.

Replace both lamp bulbs after 500 hours of use to help ensure that the UV ink is fully and evenly cured.

Note Attention Caution

CAUTION

The UV lamps and the carriage may be hot if the printer has been active. Avoid touching the lamp assembly until it is cool.

These UV lamp bulbs contain mercury, and if they are broken the vapor is toxic if inhaled. The lamp bulbs must be disposed of according to local environmental regulations.

How to Access the Lamp Housings

The housings for the two UV lamps are located on each side of the carriage. When you view the printer from the end where the Start button is located, the Right lamp is located on the Home side where the carriage parks when it is not printing. The Left lamp is located on the other (Away) side of the carriage. To access the Right lamp, make sure the carriage is in its parked position and follow the instructions below to remove a bulb.

How to Remove the UV Lamp Bulb

It is not necessary to shut the printer power off the while replacing the UV lamp bulbs. However, make sure you turn them off by de-selecting the lamp icon in the user interface before you start and allow a few minutes for the bulbs to cool down.

NOTE

Wear cotton or nitrile gloves when handling UV lamp bulbs. Avoid bare skin contact with the UV lamp bulbs. When heated, compounds from the skin can form permanent etching on the surface of the UV bulb. A contaminated bulb may fail prematurely.

Procedure

  1. From the User Interface, deselect the lamp icon to turn the lamps off and allow to cool for 5 minutes.
  2. Click on the Maintenance Tab and then select UV Bulb Replacement from the Maintenance Tools in the upper right side of the display.
    NOTE

    Accessing the Replace UV Bulb window will open the lamp assembly shutters so that the bulbs will be easily accessible later in this procedure.

  3. Lift and remove the safety guard from the carriage.
    NOTE

    When the carriage guard is removed, the carriage will raise and the green beacon will go off.

  4. Lift the magnetic lamp filter cover off of the lamp housing.

  5. Lift the lamp filter off of the lamp assembly and set aside.
  6. Open the lamp assembly by lifting on the hinged cover and rotating toward the carriage.
  7. Disconnect the UV lamp bulb connectors by pressing in the two side tabs and pulling up.
  8. Hold the wire attached to each end of the bulb and using index fingers, lift up on the ceramic bulb ends.

  9. Dispose of the old bulb per local regulations.
  10. Clean the lamp shutter and bulb with the alcohol wipe included in the kit.
  11. Pick up the new bulb by its ceramic ends and power wires, and then insert the bulb into the retainer clips.
  12. Reconnect the bulb power connectors at both ends.
  13. Close the lamp assembly by rotating the top down.
  14. Reinstall the lamp filter on top of the lamp housing.
  15. Reinstall the magnetic lamp top cover to secure the filter.
  16. Repeat this procedure if necessary to change the bulb on the other side of the carriage.
  17. Replace the safety fence.
  18. From the User Interface, reset the lamp bulb hours for the bulb replaced, then click on Back to exit.
