I hate to spill secrets, but ...

I picked it up last year at a garage sale! They wanted $35, I offered $30, and they took it. Weighed the cartridge, about 90% life left (and that's a 15,000 page cart, too!)

Cleaned the rollers (it has about 140K pages -- just broken in). Does all my two-sided and "B" size work.

I'm in the process of disposing of all the rest of my laser printers.
