content: What's the amusing part? The red light? That's quite standard for anything used in an assembly line.

content: We use a Linx inkjet printer at work with the same red light. Flashes when it is stopped, or when you are doing an edit of the print, or when it has low solvent, ink or a fault. I never buy the ink for it, the solvent use is around 40 bottles per year though, the ink tank holding 1.5l of ink being enough to run it easily between services, when the tank is cleaned to get to the pickup and coarse filter in it. All internal piping for ink and the MEK solvent is PTFE, along with all the fittings and wetted parts of the valves and pump.

content: The light is important when there is a lot of printing going on. At my work, there are several printers that print an average of 10K double sided pages per day each. So when the printer if out of paper or toner, or it jammed, it's easy to notice by the red light. Without the light, it might take an hour or so for someone to notice it stopped printing. One hour means a huge backlog.

As others have suggested, much/most equipment used in industrial production has warning lights like that to attract the attention of the support people, and to identify which equipment needs attention. There could be a dozen identical printers and you need something like that to signal WHICH printer is down.Frequenty you will see multi-color lights which indicate equipment up/down, working/waiting, etc.

content: Also, a clean room breach is something you definitely want a big, big siren for, no human will notice it and it can be devastating. A fab clean room can cost tens to hundreds of millions to restart production after even a small unscheduled delay. A whole batch of wafers ruined due to particulates can bankrupt a place.There are certainly many places where that red siren is humorously inadequate and undersized for what it is measuring.
