Especially for jobs with many sets, it is useful to check the first printed set, before all remaining sets are printed in one run.
The [Check first set] setting is available when the active workflow profile allows this setting.
For that, the [Check first set] setting of the workflow profile has to be set to [As in job].
Touch the job.
Press [Edit].
In the [Job] function, touch [Number of sets].
Ensure the [Check first set] checkbox is ticked.
Touch [OK].
