Jon,
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".
OK, sounds right.
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.
First, since you have not checked with another cartridge, is
to examine the corona wires and/or "combs" on the cart.
Sometimes the wires break at one end. Also, toner spills
could short it out, I've had that before. Bent contacts on
the cart where it connects the HV to the printer could also
be making bad/no contact.
But, the caps could be it, the symptom where it starts
working after warming up does indicate weak caps.
