Inspecting the SST Transport
After you clean the SST Transport, you should inspect the various parts to ensure that everything is
in working order. The following instructions describe the steps to inspect the SST Transport.
1. Check the side-to-side movement of the Magnetic Head.
Warning! Do not push down on the magnetic head or it will become misadjusted.
❑
Hold the Magnetic Head between your thumb and forefinger. The magnetic head
should swivel freely but when moved, it should not return to its original position
of its own accord. (Version 12 or older only.)
❑
Make sure the magnetic head is above the ticket channel.
Warning! Do not adjust the magnetic head. Once set at the factory, the adjustment should
not change. If it has been accidentally misadjusted, contact the factory for assis-
tance.
Checking Motor Speed
Note:
After June 2001 SST CPU boards no longer contain motor speed adjustment. Motor speed
is controlled by firmware (Versions 4.0.9 or higher).
Follow these instructions to check the motor speed:
1. Close the SST Transport if it is open.
Warning! Make sure that the gears are aligned properly before you shut the SST Trans-
port. Forcing it to shut when the gears are not aligned properly may bend the
teeth on the large nylon drive gear. Do not slam the SST Transport shut.
2. Carefully reinstall the unit in the device in which it resides. Turn power ON.
Note:
Do not overstress or pinch the cables. Also, ensure that all connections to the CPU Board
are proper.
3. Check the motor speed.
4. Note the current DIP switch settings.
5. Open all of the DIP switches on Switch Bank S1, located on the SST CPU Board.
6. Close DIP switch 7, and then close DIP switch 8.
