Yeah it does click when in standby / low power mode. I do the same and just power it down when its not in use. These days its only used once in a blue moon so its not really a bother to me. But yeah if someone was going to have it on 24/7 so its ready to go at a moments notice, I would recommend rigging up some kind of remote power management for the power supply (Not that I recommend any buying a 17 year old printer model).
