Lucky you. I tried to track down a fuser - got a quote of £97 + VAT (total of
about £120, or roughly $200) for a Laserjet III fuser. Second-hand from a
scrapped printer, too...
(either I'm looking in the wrong place or fusers are seriously expensive)
I've got a Panasonic KX-P4400 here that seems to need a new developer unit.
Only problem is, the fuser takes paper from the bottom and ejects it out one
side IIRC (unless it just feeds straight through and uses a roller to
realign the paper.. can't remember offhand).
The biggest problem I found was finding data on the thermistors. You need to
keep track of the temperature of the fuser and switch the power based on
that, otherwise you end up frying the thermal fuse or blowing the heater.
The other problem is the motor drive, but that's not too difficult - steal
the motor and drive gears from the printer and use them :)
I've got the LaserJet service manual here - if someone wants to sell me a
cheap LJ/LJ2/LJ3 fuser (or point me to somewhere in the UK that sells them
cheaply), I'd be happy to design something to drive it. Obviously I can't do
that without a fuser :-/
Later.
