Re: IBM 4019
Large format LED (they don't generally use lasers any more because the beam emitter has to be too far away from the drum and lenses are expensive) printers and all toner based copiers are boring now. At least 2 thermal cutouts (wax expansion / replacement required) and several thermistors, the good ones have expensive non contact ones the crap ones contact the belt or rollers increasing wear.
At least they don't catch on fire though ;)
Also damp paper is the leading cause of our service calls (next to user failure)... excessive paper curl / jams. I have seen fuser exits convered in condensation and one rusted to destruction after 6 months use.
We all also had one call where a user was adamant that the copier had flooded their office with water ? One Courtesy call later to inspect the machine we decided that the office dog was more likely to be at fault.
