Replace the UV LED unit Filter
Introduction
The printer has two UV LED units, one on each side of the carriage, to cure the UV ink during
printing. The filters in these UV LED units have a limited lifetime and must be replaced by the
operator to prolong the life of the unit and maximize curing efficiency.
When to do
These filters should be changed every two weeks.
Before you begin
It is recommended to wear gloves when handling dirty UV LED unit filters due to the possibility of
partially cured ink deposits.
Failure to replace dirty filters will result in lamps operating at a higher temperature causing
premature failures of internal components and UV LED units.
How to Replace the UV Lamp Filters
It is not necessary to shut the printer power off the while replacing the UV LED unit filters.
However, allow a few minutes after printing for the UV LED units to cool down.
NOTE
Wear cotton or nitrile gloves when handling UV LED unit. Avoid bare skin contact with filters that
are contaminated with partially cured ink.
Procedure
1.
Remove the UV lamp filter.
2.
Place a new filter in the lamp assembly.
