For best focus, custom gobos for the RoboScan Pro 918 should be made with the artwork reversed on the coated side.
See page 31 for gobo specifications.
Chrome-coated glass gobos are not recommended: they absorb more heat than enhanced aluminum gobos and are
likely to break or oxidize. The lifetime of chrome gobos is extremely short in the Pro 918; but, if used, their lifetime
can be extended somewhat by inserting the gobos with the coated side towards the lamp.

1. Remove the effects section cover.
2. Turn the gobo wheel so you can reach the desired gobo. Turn the color wheel until the open position is over
the gobo.
3. Push the gobo and retaining spring out of the back of the holder. Avoid letting the spring and gobo fall into
the effects compartment.
4. Insert the new gobo. See below for proper orientation.
5. Insert the retaining spring with the bend facing out, away from the gobo. Working through the open position
in the color wheel, push the gobo and spring all the way down into the gobo holder.

1. Remove the effects section cover as described above.
2. Turn the gobo wheel until the easiest access to the desired gobo position is obtained. Turn the color wheel
until the open position is over the gobo position.
3. Turn the gobo holder until you can see the tab on the holder retaining spring.
4. Grip the tab on the retaining spring with a pair of small (needlenose) pliers. Place your index finger over the
spring to prevent it from falling into the fixture. Open the spring and remove it from the gobo holder.
5. Remove the gobo holder from the bearing by pulling it forwards towards the mirror.
6. Push the gobo and gobo retaining spring out of the holder.
7. Insert the new gobo. See below for proper gobo orientation.
8. Insert the retaining spring with the bend facing out, away from the gobo. Push the gobo and spring all the
way down into the gobo holder.
9. Replace the gobo holder in the bearing. Do not force the holder into the bearing: it will go in easily if it is
installed straight.
10. Grip the retaining ring by the tab with the pliers. Place your thumb on the back of the gobo holder to press it
all the way down in the bearing and use your index finger to hold the other end of the spring on the holder.
Open the spring and place it in the groove.
