of the head. The gel string is held in tension and may roll back after being

the back of the Scroller Cartridge and slide the cartridge back onto the tabs.

Gel Strings
You can change the gel string in your fixture. Replacement strings must have a minimum
of 2 frames or a maximum of 20 frames of gel media. If you are going to make or purchase
your own gel strings, follow the specifications in the Source Four Revolution User Manual
to ensure proper performance.
Replace the gel string:
Step 1: Remove the scroller cartridge from the fixture by pulling the latch forward and
pulling the cartridge up out of the head. The gel string is held in tension and may
roll back after being released from the head.
Step 2: Place the cartridge on a flat surface and, if necessary, wind the gel string back
onto the right spool.
Step 3: When the attachment tab on the left spool is revealed at the end of the leader,
release the tab from the attachment point.
Step 4: Carefully roll up the gel string. When the gel string is rolled up, you will see the
trailer attachment point on the right spool.
Step 5: Detach trailer from the right spool and remove the gel string.
Step 6: Attach the replacement gel string’s trailer to the right spool by feeding the
attachment tab down through the bar/slot and around onto the attachment point.
Step 7: Roll the gel string tightly onto the right spool. Leave enough of the scroll unrolled
to allow you to attach the leader to the left spool. Keep tension on the scroll.
Step 8: With your other hand, placing yourthumb on the bar/slot portion of the left spool,
spin the spool away from the center of the cartridge until the attachment point is
facing up, then refer tothe sticker on the left spool for the propernumber of turns
to spin the spool to generate the proper tension in the spring. Continue spinning
the spool about 1/4 turn until the bar/slot is visible and facing the center of the
scroller cartridge, as shown above.
Step 9: Feed the end of the leader up through the bar/slot and over onto the attachment
point.
Step 10: When the leader is attached to the left spool, let go of the spools. The gel scroll
should spool a number of frames onto the left spool and then settle.
Step 11: Reset the fixture to calibrate and ensure proper performance of the scroller.
