I have a xerox phaser 6125 that has printed less than 2000 pages in its lifetime.
When I moved from Sea Level to about 5000 Ft, I began to notice that some colors, mosty Reds and Yellows seem to flake off the page very easily.
Again this printer has printed less than 2000 pages. This problem seemed to start after moving to a higher altitude.
I see no settings in the printer for high altitude. It seems most ceratinly that the ink needs to "cook" on the page a little hotter or longer just as it takes longer to boil an egg. Oddly enough, I have many printers and all of the others have adjustments for high altitude and once adjusted worked flawlessly in the new location. Some other printers exhibited similar resuults in the higher altitude before making the adjustment.
I thought perhaps one of the resets might force redetection of altitude casing the fuser to behave differently?
