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.
When to do
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.
