Based on the info coming through on the list a "cold" fuser would produce
toner that would wipe off/flake off of the printed sheet. This is not
happening in my case so I am guessing the fuser is getting hot "enough". The
current hive thinking seems to be toward the corona wire - specifically
failing caps in HV needing time to warm up to specs before working properly.
