3.5 Parts Camera UV Lamp Replacement

Point

The UV lamp will grow dim over time, and should be replaced periodically (after 2000

hours of machine operation). The jig (DFPJ0060) is necessary to measure the UV-lamp

bracket height.

Procedure

Caution

Ensure the nozzle station is lowered before carrying out

inching. The XY-robot will be damaged if it interferes with

the nozzle station.

WARNING

Always be sure to cut the main power before carrying out

any work.

1. Use the inching operation to move XY robots 1 and 2 to “side 2” of the machine.

Note: The procedure for replacing the UV lamp at XY robot 1 is explained here. When

replacing the UV lamp at XY robot 2, move XY robots 1 and 2 to “side 1” of the

machine.

2. Detach the cover from the end of the camera unit.

3. Remove the UV lamp holder together with its bracket.

4. Extract the UV lamp from the UV lamp holder, and install a new UV lamp.

Note: Handle the UV lamp with care. The glass portion of the lamp may break if excessive

force is applied.

5. Reattach the UV-lamp holder bracket and cover after replacing the lamp. Next,

remove the nozzle station shutter plate, and place the jig (DFPJ0060) on the top of

the nozzle station which is at the uppermost position. Slide the jig back and forth

ensuring there is no interference with the UV-lamp bracket.
