Depends on whether it's been rehabbed. Think the fuser is rated for 60k. Service manual shows intervals.
The bay shows many units for sale with 200k+. Starting at $200. Think I paid 75$ for a complete consumables kit minus the fuser. (rollers, gears, pads, etc.) Takes 45 minutes to do. (took me an hour prep time to make sure I knew what to do.)
Most well made things run for a long, long time if the prescribed preventative maintenance is done.
This one does a better job with the sub models, including the second test page:
