[comp.laser-printers] Does anybody know Carlson densitometers?

A colleague is seeking technical information on a Carlson T/R 400 photographic
densitometer so he can attempt some repairs.  Anything in the way of an
operator's manual, schematic, maintenance manual, etc. would be helpful.

The unit operates well for a few minutes and then fails to indicate properly.
Any information or advice would be appreciated.

Please send any response to me directly as I am not enrolled on this list.
