Your car probably WOULD overheat or malfunction if you put the pedal to the floor for 20 straight minutes...that's what 8k 30/4k 120/4k 60/4k 30 HQ represent. Powerful computers without cooling do, as well. Copiers have a "duty cycle" that represents an approx. number of pages per month they can handle, and if you repeatedly and significantly exceed that, it increases the likelihood that it will break down (and can make you ineligible for a warranty replacement of the consumables).
Actually it wouldn't...want to know why, because modern cars have rev limiters and speed limiters to make sure they are reliable and they do not overheat. If you drive any modern car at top speed for 20 min and it overheats then you need to get a new car because it means either the rev limiter or speed limiter are not doing their job.
I get all modern equipment has well documented constraints on use....specifically though....thermal shutdown concerns are unique because many factors can make the actual time of shutdown vary widely. You can predict a copier will break down because you printed too much, you can predict a car will break down because you ran over a pothole, you cannot predict how close you will come to a thermal shutdown prior to a video shoot.
In fact, if you drove any modern car at top speed for every single day of its existence right up until the warranty expired....if it overheated even once you would still be covered by the warranty. That's because you were still driving it within the specifications set forth by the manufacturer and those parameters are enforced by the speed limiter and rev limiter.
