When the injector is not operating, open the injector tower door.

The injector goes through the following steps:
• The turret rotates to verify that the needle support assembly was
removed, then rotates to determine what type of turret is installed
• The syringe carriage moves all the way down, then moves back up
again and clears the turret
• The syringe carriage steps down until it touches the turret. This sets
its position relative to the turret.
• The plunger moves to calibrate stops
When the alignment is complete, the Ready light turns on and the sampler
returns to the ready state. Install the needle support assembly and syringe.
If the injector fails alignment, see
