Roland PNC-1600 Flatbed cutter

Does anybody have any knowledge of a "Roland" Flatbed cutter/plotter (PNC-1600 CAMM-1) and do they have a copy of the schematics that they could e-mail me a copy.

This is an older machine and Roland doesn't have them under warranty and can'tgive me any information on it.

I have had this machine for over 18 years and it has been a workhorse but the other day when I turned it on I got a "motor error" and I would like to get it running again.

Is they anyone out there that ever owned that model or a "Roland PNC-1900 Camm-1" which was a little larger.

Please help if you can.

Thanking you in advance
