How to Replace the Lamp Housing
Place the lamp housing back into the carriage bucket.
1.
Replace the old filter that was removed from the top of the housing with a new one.
2.
Rotate the interlock safety bracket back into position to lock the lamp housing in place.
3.
Reconnect the UV power cable connector to the top of the UV lamp housing.
4.
Repeat the above two sets of procedures to change the bulb in the other lamp housing.
5.
Note:
We recommend that both UV Lamp bulbs be replaced at the same time to ensure that
the curing effect is balanced when printing in both directions.
Replace the carriage guard onto the carriage base.
6.
Slide the maintenance station drawer gently to close it.
7.
Note:
A hard bump can break the meniscus vacuum in the ink lines and thus allow air into the
lines, which blocks the printhead nozzle until a purge is performed.
Unlock the AC power switch and power on the printer.
