Recovering from a head collision

About this topic

This topic describes what to do in the event that a pipette head collides with an object, such as an accessory, labware, or shelf. A head collision can occur for various reasons, for example, if the wrong profile is initialized, the teachpoints are not correct, or the wrong labware is placed on the shelves. A head collision can result in a bent shelf, bent pipette tips, and other problems.

Procedure

To recover from a head collision:

1	Follow the procedure Recovering from a power outage.

2	Clean up any spills that might have occurred as a result of the collision.

3	Carefully inspect the impacted parts for signs of damage:

•	Pipette barrel or tip. Compare the affected area to the surrounding barrels or tips. Look for bent barrels and damaged seals.

•	Shelves. Inspect the shelves for flatness. Verify the teachpoints.

•	Alignment Shelf. Verify the rollers and springs are not damaged and still allow plates to be easily picked and placed.

Make sure the specific functionality of shelves has not been compromised.

4	For each axis, jog the pipette head in both directions while listening for any new noise. If new noises are present or if any axis movement is impaired, contact Automation Solutions Technical Support.

5	Move to the teachpoints and verify the alignment in the x‑, y‑, and z-axes.

If the x‑ or y‑axis are misaligned, contact Automation Solutions Technical Support.
