Robots that were manufactured before the 5th of September, 2019 will need to have the Pipette-Mount connection ribbon for each mount adjusted to attach to the GEN2 pipettes. The connection ribbon will not be able to reach the connector pins of the GEN2 pipettes without making this adjustment. 

How to determine the OT-2 robot manufacturing date:

The manufacturing date of the OT-2 robot can be identified via the robot’s serial number. The robot’s serial number is located on the back of the robot under the barcode. It may also be the robot name displayed in the Opentrons App when the robot is connected. The robot serial number should start with “OT2P” or “OT2CEP”. The numbers that follow “OT2P” or “OT2CEP” are the manufacturing date of the robot in the Year-Month-Day (with no separators) date format (YYMMDD). 

For example, if the serial number starts with: 

OT2CEP20190618...

That would mean the robot was manufactured on the 18th of June, 2019. This robot would need to adjust the Pipette-Mount connection ribbons in order to attach GEN2 pipettes. Any robots that have “2018” as the manufacturing year will need to adjust the Pipette-Mount connection ribbons. 

If a robot has a manufacturing date of 2019, it may be best to attempt to attach a GEN2 pipette first to confirm that the Pipette-Mount connection ribbons need to be adjusted. 

If you are having trouble identifying whether an OT-2 robot needs to adjust the Pipette-Mount connection ribbons, please contact the Opentrons Support team for further assistance.

Before starting:

  1. Remove all pipettes from the robot mounts.
  2. In the app, select “Pipettes & Modules” underneath the connected robot’s name. Click “attach” on the left pipette mount (this process will need to be repeated for the right mount as well). The left mount will lower at the front of the robot. 
  3. Power the robot off via the switch on the side of the robot.
  4. With the left mount lowered, pull it down to make sure that the Pipette-Mount connection ribbons are exposed

Adjusting the Pipette-Mount Connection Ribbon

Step 1.)

Remove the pipette connector from the plastic enclosure. It helps to pull down on the bottom "tooth" of the enclosure with one hand while removing the connector with the other.

Step 2.) 

Remove the connector ribbon from the plastic casing. It may help to use a screwdriver to assist in removing the ribbon from its casing. 

Step 3.) 

Place the pipette connector back in the plastic enclosure so that there is enough slack for the ribbon to reach the GEN2 pipette. Rewire the connector ribbon through the plastic casing.

Step 4.) 

Attach the GEN2 pipette to ensure the pipette connector reaches the pins of the pipette. If the connector does not reach the pins, redo the previous 3 steps above so that there is enough slack for the ribbon to reach the pins. 

Once you have confirmed that the GEN2 pipette can be attached, the process above will need to be repeated for the right mount.
