Old LaserJets
Old HP LaserJets will just keep going and going in the main.
4Si had a duty cycle of 75,000 pages per month, of course the feed rollers would need replaced and occasional fuser unit but they weren't that expensive proportionately.
I also remember servicing 3Si's (for feed rollers again) which were on 1.5 million pages plus.
More problematical were the smaller office / personal ones where you'd get people using non-laser acetate sheets or labels (remember those) which would melt onto the fuser. Kept me in a job I suppose.
