The LaserJet II II and Laserwriter II III were discussed with interest, 
here in this list, last month. My LJ III has a failed "laser scanner" 
module; does anyone have a likely working unit available? Also the AC 
power controller, that's useful if you don't need one yourself.

I'm not talking about the HP LaserJet IIP or IIIP or 4P or other HP 
printer models. I'm not sure if the original Apple Laserwriter uses 
these parts; if you have one of those, good luck, want some more parts? ;)

The scanner is the big black thing under the lid of the printer. It has 
a laser and a motorized scanner mirror, that mechanically sweeps the 
laser across the toner-cartridge drum. When the printer is about to 
print, you hear that scanner-motor wind up to speed before the paper is 
fed (whir-r-rr-R-RR-RRR!) when it works. These rarely fail, so I haven't 
kept spares around. Don't disassemble the unit for the motor, just offer 
the whole thing.

I'd not mind getting an AC power supply/controller. That's the cubical 
thing in the back that the AC power cord plugs into. Don't need the air 
filter (those tend to be fragile with age), they have a small fan (you 
can supply that or not). These things fail pretty often, I don't need a 
nonworking unit, have plenty of those.

Shipping to NJ 08618. Contact me privately. Thank you.
