Calvin Du, the tech, contacted me within minutes of the service request ticket being sent. After explaining the issue (unusual noise?!?), Calvin had me record the printer running and send it to him. Shortly thereafter, he arrived with the replacement part needed, after diagnosing the issue from the recording! Printer was fixed and up and running within 90 minutes of the original service request. Highly recommend!
