You notice the machine is processing mail but producing an unusually high number of errors or rejects. What is the BEST action?

A spike in errors or rejects signals a malfunction that, if ignored, will mishandle large volumes of mail. The best response is to stop or flag the issue according to procedure, check for an obvious, trained-for cause, and report the malfunction so it can be properly fixed before more mail is affected. Continuing to run a malfunctioning machine, tampering with internal parts you are not trained to service, or concealing the rejected mail all worsen the problem. The exam rewards vigilance and prompt, procedure-based reporting that protects mail quality and prevents larger downstream problems.
