How to Clean the UV Lamp Filter

Introduction

The top of the housings for the left and right UV lamps contain a filter that keeps dust and other airborne particles from entering the lamp housings. If the filter becomes clogged with dust and debris it can cause overheating of the lamps.

About this task

Check the condition of the filters weekly and clean them as needed. If dust accumulates, this can lead to overheated lamps and results in an error message. Clean the filters at least once every three months to avoid overheating. If you receive a lamp overheat error, check for dust or debris. If you get a lamp overheat error and there is no dust on the filter, call for service immediately.

NOTE

When you change a UV lamp bulb, replace the filter.

Before you begin

  1. Turn off the ink temperature.

  2. Turn off UV lamps.

Required tools

small hand vacuum cleaner

NOTE

Always wear cotton gloves and protective safety glases when handling UV lamps and the reflecting shutters.

IMPORTANT

Failure to clean the filters can lead to overheating of the lamps and result in a shorter lamp life.

Procedure

  1. Wait for the lamp fans to stop to ensure the housing has cooled down.
  2. Remove the lamp filter by first lifting one corner, then bend it in the center by placing your finger under the filter and lift it away from the power connector and off the lamp housing.

  3. Move away from the printer and use a vacuum cleaner to remove any debris or dust.
  4. Replace the lamp filter by inserting one long edge into the channel on top of the lamp housing, and then squeeze the filter so that the middle bulges and allow the other edge to slide into the other channel.
  5. Repeat steps 2 to 4 for the filter in the other UV lamp assembly.
