Mita DC-4090 Owner's Manual Needed

[Xthe17th]

I bought a Mita (now Kyocera) DC-4090 copy machine at an estate sale auction several weeks ago. It appears to work, but is out of toner. I am seeking the Owner's Manual (or a copy of one) for this machine. In particular, I would like to know how the special management features (access codes) work. Also, it came with a HUGE collator (not the AS-S2120) that connects to it with an inch thick cable, but I cannot figure out how it mechanically connects to the output.

Thanks,

PS: It also came with a large capicity paper deck and collator/sorter for a Minolta of which I cannot use. LMK if anyone is interested in these components.
