• The syringe carriage motor has a problem.
• The syringe carriage cannot find its home position.

Suggested actions
1. Ensure the syringe is installed correctly. For more information, see
“Selecting and installing syringes” on page 49.
2. Ensure the syringe meets specifications.
3. Check the on-column injection mode parameter. If the parameter was set
incorrectly for on-column injection, check for damage to the inlet liner and
column.

5. Press the STOP button on the injector to clear the fault indicators. Restart
the sequence.
