Update on the LaserWriter. I bought a genuine toner (NOS, never opened) on eBay and installed it. I was able to print a test page and found that the printer only had 3050 pages printed! The printouts are pretty dirty however, with toner lines on the right side of the page.

Well hopefully yours works out better than mine. I did the same thing a few years back (bought a NOS toner for my Select 360 off eBay) and the wiper blade was dried out and broken leaving streaks on all my pages. I gave up on it and got a reconditioned one for $45 and its worked great ever since. When I got my 12/640PS I skipped eBay entirely and bought a toner from the same site. I have a feeling those NOS toners on eBay are just too old by now.
