Re: [hylafax-users] continuous user DCN errors w/ Canon ImageRunner 1670F copier w/ fax

Lee-

Thanks for the reply - this particular model seems to be the only
trouble-maker. Faxes from any number of other machines cause no problems
whatsoever. Sending from this same machine to various models/brands of
fax machines seem to complete without issues, but of course, physical
machines don't produce such detailed logs to help with debugging. I'll
keep testing and see if I can find something else that might be going on.

Cheers,
-Alan
