Omega PS150: “Object reference not set to an instance of an object” When Copy is Selected

Overview

Use this article when an Omega PS150 displays the error “Object reference not set to an instance of an object” after a user selects Copy on the attached MFD.

Printing may continue to work normally while copying fails.

Applies to

• All Omega terminal versions attached to an MFD or copier.

• Blueprint or Uniprint environments that use Omega copy control.

• Environments where Copy Lines are configured in Pharos Administrator or Uniprint Output Management.

Before you start

1. Record the Omega terminal name and the attached MFD or copier model.

2. Confirm whether the issue occurs only when Copy is selected and whether printing still works.

3. Confirm that you have administrator access to the device configuration.

4. Do not change Copy Lines based only on the error message. The entries must match the signals returned by the attached copier.

Steps

1. Open the appropriate device configuration:

   1. In Pharos 7.2, open Pharos Administrator and go to the Pharos Managed Copier context.

   2. In later versions of Uniprint, go to Output management > Devices, choose the device, and then select Copier > Copy Line Configuration.

2. Review every configured copy-line entry.

3. If any entry is set to N/A, remove it or replace it with the correct copy-line value for the attached MFD.

4. Confirm that the copy-line names and values match the copier configuration.

5. Put Copy Line 0 at the top of the list in the Copy Control Configuration page.

6. Save the configuration.

7. If the environment requires terminal configuration propagation, update the relevant Collector or server configuration before testing again.

8. On the Omega PS150, select Copy and test a representative copy workflow.

Validation

1. The Copy screen opens without the “Object reference not set to an instance of an object” error.

2. A copy can be completed successfully.

3. The copy is recorded and charged with the expected attributes.

4. Printing from the Omega PS150 continues to work.

5. Confirm that no Copy Lines entries remain set to N/A.

Notes

• The Copy Lines configuration tells Omega how to interpret signals returned by the copier. It does not configure the copier itself.

• If the error continues after the Copy Lines are corrected, collect the Omega terminal name, product and version, MFD model, Copy Lines configuration, and relevant logs, then escalate to Technical Support.
